+<p>Bar Chart, is a chart that presents the comparisons among discrete data. The length of the bars is proportionally related to the categorical data.</p>
+<p>To set the bar chart, you need to set the <code>type</code> of <code>series</code> as <code>'bar'</code>.</p>
+<p><a href="https://echarts.apache.org/option.html#series-bar" rel="nofollow noopener noreferrer" target="_blank">[Option]</a></p>
+<h2 id="simple-example"><a href="#simple-example" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Simple Example</h2>
+<p>Let's begin with a basic bar chart:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this case, the x-axis is under the category type. Therefore, you should define some corresponding values for <code>'xAxis'</code>. Meanwhile, the data type of the y-axis is numerical. The range of the y-axis will be generated automatically by the <code>data</code> in <code>'series'</code>.</p>
+<h2 id="multi-series-bar-chart"><a href="#multi-series-bar-chart" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Multi-series Bar Chart</h2>
+<p>You may use a series to represent a group of related data. To show multiple series in the same chart, you need to add one more array under the <code>series</code>.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="customized-bar-chart"><a href="#customized-bar-chart" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Customized Bar Chart</h2>
+<h3 id="styles"><a href="#styles" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Styles</h3>
+<p>It is a good idea to install the style of Bar Chart by using <a href="https://echarts.apache.org/option.html#series-bar.itemStyle" rel="nofollow noopener noreferrer" target="_blank">'series.itemStyle'</a>. Description of the SCI:</p>
+<ul>
+<li>Color of column(<code>'color'</code>);</li>
+<li>Outline color(<code>'borderColor'</code>), width(<code>'borderWidth'</code>), type(<code>'borderType'</code>) of column;</li>
+<li>Border radius of column(<code>'barBorderRadius'</code>);</li>
+<li>Transparency(<code>'opacity'</code>);</li>
+<li>Shadow type(<code>'shadowBlur'</code>, <code>'shadowColor'</code>, <code>'shadowOffsetX'</code>, <code>'shadowOffsetY'</code>)</li>
+</ul>
+<p>Here is a example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this case, we defined the style of the bar chart by <code>'itemStyle'</code> of corresponding <code>series</code>. For complete configuration items and their usage, please check the configuration item manual: <a href="https://echarts.apache.org/option.html#series-bar.itemStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.itemStyle</code></a>。</p>
+<h3 id="width-and-height-of-column"><a href="#width-and-height-of-column" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Width and Height of Column</h3>
+<p>You can use <a href="https://echarts.apache.org/option.html##series-bar.barWidth" rel="nofollow noopener noreferrer" target="_blank"><code>barWidth</code></a> to change the width of the bar. For instance, the <code>'barWidth'</code> in the following case was set to <code>'20%'</code>. It indicates that width of each bar is 20% of the category width. As there are 5 data in every series, 20% <code>'barWidth'</code> means 4% for the entire x-axis.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In addition, <a href="https://echarts.apache.org/option.html#series-bar.barMaxWidth" rel="nofollow noopener noreferrer" target="_blank"><code>barMaxWidth</code></a> has limited the maximum width of the bar. For some small value, you can declare a minimum height for the bar: <a href="https://echarts.apache.org/option.html#series-bar.barMinHeight" rel="nofollow noopener noreferrer" target="_blank"><code>barMinHeight</code></a>. When the corresponding height of data is smaller than the l [...]
+<h3 id="column-spacing"><a href="#column-spacing" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Column Spacing</h3>
+<p>There are two kinds of column spacing. One is the spacing between different series under the same category: <a href="https://echarts.apache.org/option.html#series-bar.barWidth" rel="nofollow noopener noreferrer" target="_blank"><code>barWidth</code></a>. The other is the spacing between categories: <a href="https://echarts.apache.org/option.html#series-bar.barCategoryGap" rel="nofollow noopener noreferrer" target="_blank"><code>barCategoryGap</code></a>.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this case, the <code>barGap</code> is <code>'20%'</code>. That means the distance between bars under the same category is 20% of the bar width. For instance, if we set the <code>barCategoryGap</code> to <code>'40%'</code>, the gap on each side of the bar will take 40% place in categories (compared with the width of the column).</p>
+<p>Usually, <code>barWidth</code> is not necessary to be clarified if <code>'barGap'</code> and <code>barCategoryGap</code> was set. If you need to make sure the bar is not too wide while the graph is large, try to use <code>barMaxWidth</code> to limit the maximum width of bars.</p>
+<blockquote>
+<p>In the same cartesian coordinate system, the property will be shared by several column series. To make sure it takes effect on the graph, please set the property on the last bar chart series of the system.</p>
+</blockquote>
+<h3 id="add-background-color-for-bars"><a href="#add-background-color-for-bars" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Add Background Color for Bars</h3>
+<p>You might want to change the background color of bars sometimes. After ECharts v4.7.0, this function can be enabled by <a href="https://echarts.apache.org/option.html#series-bar.showBackground" rel="nofollow noopener noreferrer" target="_blank">'showBackground'</a> and configured by <a href="https://echarts.apache.org/option.html#series-bar.backgroundStyle" rel="nofollow noopener noreferrer" target="_blank">'backgroundStyle'</a>.</p>

+<p>Sometimes, we hope to not only figure series separately but also the trend of the sum. It's a good choice to implement it by using the stacked bar chart. As the name suggests, in the stacked bar chart, data in the same category will be stacked up in one column. The overall height of the bar explained the change of total.</p>
+<p>There is a simple way to implement a stacked bar chart by ECharts. You need to set the same string type value for a group of series in <code>stack</code>. The series with the same <code>stack</code> value will be in the same category.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this case, the position of the second series is based on the position of the first series, the height increased is corresponding to the first series' height. Therefore, from the position of the second series, you can find the changing trend of the sum of the two.</p>
+<blockquote>
+<p>The value of <code>stack</code> explained what series will be stacked up together. Theoretically, the specific value of 'stack' is meaningless. However, we prefer some suggestive strings for the convenience of reading.</p>
+<p>For instance, here is a chart with 4 series that counted the amount of male and female. "adult male" and "boy" need to be stacked while "adult female" and "girl" need to be stacked. In this case, the suggestive value of <code>stack</code> is <code>'male'</code> and <code>'female'</code>. Although meaningless strings like <code>'a'</code> and <code>'b'</code> can achieve the same effect but the code will have worse readability.</p>

+<p>We can use the following code to build a line chart which has x-axis as <code>category</code>, y-axis as <code>value</code>:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this case, we set the type of axis to <code>category</code> and <code>value</code> under <code>xAxis</code> and <code>yAxis</code>. We also clarified the content on the x-axis through <code>data</code>. In <code>series</code>, we set the type to <code>line</code>, and specify the values of three points through <code>data</code>. In this way, we got a simple line chart.</p>
+<blockquote>
+<p>The <code>type</code> here can be omitted because the defaults of the axis are <code>value</code> while <code>xAxis</code> has specified the category's <code>data</code>. In this case, <code>ECharts</code> can recognize that this is a category axis.</p>

+<p>How to implement if we want the line chart to be continuous? The answer is simple, as long as every value in <code>data</code> of the <code>series</code> is represented by an array containing two elements.</p>

+<p>Line style can be changed by <code>lineStyle</code> setting. You can specify color, line width, polyline type and opacity etc.. For details, please see the handbook <a href="https://echarts.apache.org/option.html#series-line.lineStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.lineStyle</code></a> to figure out.</p>
+<p>Here is an example of setting color, line width and type.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>When we set the line width here, the line width of items will not change. The line style of items needs to be set separately.</p>
+<h3 id="item-style"><a href="#item-style" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Item Style</h3>
+<p>Item style can be change by <a href="https://echarts.apache.org/option.html#series-line.itemStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.itemStyle</code></a>. It included <code>color</code>, <code>borderColor</code>, <code>borderStyle</code>, <code>borderWidth</code>, <code>borderType</code>, <code>shadowColor</code>, <code>opacity</code> and so on. It works the same as the <code>lineType</code>, so we will not do further discuss.</p>

+<p>Pie charts are mainly used to show the proportion of several categories compared with the total. The radians represent the proportion of each category.</p>
+<h2 id="simple-example"><a href="#simple-example" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Simple Example</h2>
+<p>The config of the pie chart is not completely the same as the line chart and bar chart. There is no need to configure the axis. The name and value of data need to be defined in the series. Let's begin with a basic pie chart:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>To be mentioned, the <code>value</code> here does not need to be percentage data. ECharts will proportionately distribute their corresponding radians in the pie chart depending on all the data.</p>

+<h3 id="radius-of-pie-chart"><a href="#radius-of-pie-chart" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Radius of Pie Chart</h3>
+<p>The radius of pie chart can be defined by <a href="https://echarts.apache.org/option.html#series-pie.radius" rel="nofollow noopener noreferrer" target="_blank"><code>series.radius</code></a>. Both percent string(<code>'60%'</code>) and absolute pixel string(<code>'200'</code>) are available.

+<p>By default, if the data sum is 0, the series will divide the shape equally.

+<p>Doughnut charts are also used to show the proportion of values compared with the total. Different from the pie chart, the blank in the middle of the chart can be used to provide some extra info. It makes a doughnut chart commonly used chart type.</p>
+<h2 id="basic-doughnut-chart"><a aria-hidden="true" href="#basic-doughnut-chart" tabindex="-1"><span class="icon icon-link"></span></a>Basic Doughnut Chart</h2>
+<p>In ECharts, the radius of the pie chart could also be an array with 2 elements. Every element in the array could be string or value. The first element represents the inner radius while the second one is the outer radius.</p>
+<p>The bar chart, from this perspective, is a subset of the doughnut chart that has inner radius equals to 0.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>If we set one radius to string of a percentage value, while the other to a value, the inner radius will be smaller than the outer radius in some resolution. ECharts will choose the smaller element for the inner radius automatically. However, it will still cause not an unexpected outcome.</p>

+<p>The previous case gives you a way to show fixed text in the middle of doughnut chart. The next case will show you how to display the corresponding text of the sector highlighted by the mouse. The general idea is to fix <code>label</code> in the middle of the chart while hiding <code>label</code> in default.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this case, <code>avoidLabelOverlap</code> is used to control whether ECharts adjust the position of label to avoid overlaps. Default value of <code>avoidLabelOverlap</code> is <code>true</code>. We want the label to be fixed in the middle so that we need to define it as <code>false</code>.</p>
+<p>Therefore, the middle of doughnut chart will show the <code>name</code> of the highlighted sector.</p></div> <div class="table-of-contents"><h4 class="toc-container-header">In This Page</h4> <ul><li class="toc2"><a href="/echarts-handbook/en/application/chart-types/pie/doughnut#basic-doughnut-chart">Basic Doughnut Chart</a></li><li class="toc2"><a href="/echarts-handbook/en/application/chart-types/pie/doughnut#show-text-in-middle-of-doughnut-from-highlighted-sector">Show Text In Middl [...]

+<p>Scatter Chart, a frequently used chart type, was constructed with several "points". These points sometimes represent the position of the value in the coordinate system (cartesian coordinate system, geo coordinate system, etc.), sometimes the size and color of items can be mapped to the value, represent high-dimensional data.</p>
+<h2 id="simple-example"><a href="#simple-example" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Simple Example</h2>
+<p>The following example is a basic scatter chart configuration with the x-axis as category and the y-axis as value:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="scatter-chart-in-cartesian-coordinate-system"><a href="#scatter-chart-in-cartesian-coordinate-system" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Scatter Chart in Cartesian Coordinate System</h2>
+<p>In the previous case, the x-axis of the scatter chart is a discrete category axis and the y-axis is a continuous value axis. However, the normal scene for the scatter chart is to have 2 continuous value axis (also called the cartesian coordinate system). The series type is different in that both x-axis and y-axis value are included in <code>data</code>, but not in <code>xAxis</code> and <code>yAxis</code>.</p>

+<h3 id="symbol-style"><a href="#symbol-style" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Symbol Style</h3>
+<p>Symbol refers to the item shape in a scatter chart. There are three types of config available. The first is ECharts built-in shape, the second is image, the last is the SVG path.</p>
+<p>The built-in shape in ECharts included: <code>'circle'</code>, <code>'rect'</code>(rectangle), <code>'roundRect'</code>(rounded rectangle), <code>'triangle'</code>, <code>'diamond'</code>, <code>'pin'</code> and <code>'arrow'</code>. To use built-in shapes, you need to state the <code>symbol</code> to the corresponding string.</p>
+<p>If you want to define the shape as any image, try to use <code>'image'</code> following by the path, eg. <code>'image://http://example.com/xxx.png'</code> or <code>'image://./xxx.png'</code>.</p>
+<p>ECharts <code>symbol</code> also supports SVG vector graphics. You can define <code>symbol</code> as an SVG file path that starts with <code>'path://'</code> to locate the vector graphics. The advantages of vector graphics are smaller size and no jagged or blurred.</p>
+<p>Method to find the SVG path: Open an <code>SVG</code> path; Find the path similar as <code><path d="M… L…"></path></code>; Add <code>d</code>'s value after <code>'path://'</code>. Let's check how to define an item to vector shape of heart.</p>
+<p>Firstly, we need an <code>SVG</code> file of a heart. You can draw one by vector editing software, or download one from the internet. Here is the content:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-xml line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" [...]
+<p>In ECharts, define config <code>symbol</code> as a path of d:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>In this way, we have a heart vector of the item.</p>
+<h3 id="symbol-size"><a href="#symbol-size" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Symbol Size</h3>
+<p>The size of symbol is defined by <a href="https://echarts.apache.org/option.html#series-scatter.symbolSize" rel="nofollow noopener noreferrer" target="_blank"><code>series.symbolSize</code></a>. It can be s pixel value of the item size, or an array included two numbers, to define the width and height.</p>
+<p>Besides, it can be defined as a call back function. Here is an example of the format:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-ts line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>The first argument is the data value, and the second argument included other arguments of the data item. In the following instance, we define the size of the item proportional related to the data value.</p>

+<p>Data in <a href="en/get-started">Getting Started Example</a> is directly updated by using <code>setOption</code>. But in many cases, data need to be filled by asynchronous loading frequently. <code>ECharts</code> can implement asynchronous loading in a simple way. You can get data asynchronously through a function such as jQuery and use <code>setOption</code> to fill in data and configs after the chart initialized.</p>

+<p>You need to use <code>name</code> to "navigate" ECharts when updating data. In the previous example, the chart can update normally depending on the order of series, but we recommend you to add the <code>name</code> data while updating data.</p>
+<h2 id="loading-animation"><a href="#loading-animation" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>loading Animation</h2>
+<p>When it takes a long time to load the data, the user is facing the empty chart with only axes will wonder if there are bugs appear.</p>
+<p>ECharts have a simple loading animation by default. You can call <a href="api.html#echartsInstance.showLoading">showLoading</a> to display. When the data loading was completed, call <a href="api.html#echartsInstance.hideLoading">hideLoading</a> to hide the animation.</p>

+<p>This is a tiny example, introducing how to implement dragging of graphic elements in Apache ECharts<sup>TM</sup>. From this example, we will see how to make an application with rich intractivity based on echarts API.</p>
+<iframe width="100%" height="400" src="https://echarts.apache.org/examples/en/view.html?c=line-draggable"></iframe>
+<p>This example mainly implements that dragging points of a curve and by which the curve is modified. Although it is simple example, but we can do more based on that, like edit charts viually. So let's get started from this simple example.</p>
+<h2 id="implement-basic-dragging"><a href="#implement-basic-dragging" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Implement basic dragging</h2>
+<p>First of all, we create a basic <a href="https://echarts.apache.org/option.html#series-line" rel="nofollow noopener noreferrer" target="_blank">line chart (line series)</a>:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>Since the symbols in line is not draggable, we make them draggable by using <a href="https://echarts.apache.org/option.html#graphic" rel="nofollow noopener noreferrer" target="_blank">graphic component</a> to add draggable circular elements to symbols respectively.</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>In the code above, API <a href="api.html#echartsInstance.convertToPixel">convertToPixel</a> is used to convert data to its "pixel coodinate", based on which each graphic elements can be rendered on canvas. The term "pixel coodinate" means the coordinate is in canvas pixel, whose origin is the top-left of the canvas. In the sentence <code>myChart.convertToPixel('grid', dataItem)</code>, the first parameter <code>'grid'</code> indicates that <code>dataItem</code> should be converted in [...]
+<p><strong>Notice:</strong> <code>convertToPixel</code> should not be called before the first time that <code>setOption</code> called. Namely, it can only be used after coordinate systems (grid/polar/...) initialized.</p>
+<p>Now points have been made draggable. Then we will bind event listeners on dragging to those points.</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>In the code above, API <a href="api.html#echartsInstance.convertFromPixel">convertFromPixel</a> is used, which is the reversed process of <a href="api.html#echartsInstance.convertToPixel">convertToPixel</a>. <code>myChart.convertFromPixel('grid', this.position)</code> converts a pixel coordinate to data item in <a href="https://echarts.apache.org/option.html#grid" rel="nofollow noopener noreferrer" target="_blank">grid (cartesian)</a>.</p>
+<p>Finally, add those code to make graphic elements responsive to change of canvas size.</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="add-tooltip-component"><a href="#add-tooltip-component" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Add tooltip component</h2>
+<p>Now basic functionality have been implemented by parte 1. If we need the data can be displayed realtime when dragging, we can use <a href="https://echarts.apache.org/option.html#tooltip" rel="nofollow noopener noreferrer" target="_blank">tooltip component</a> to do that. Nevertheless, tooltip component has its default "show/hide rule", which is not applicable in this case. So we need to customize the "show/hide rule" for our case.</p>

+<p>Rich text can be used in Apache ECharts<sup>TM</sup> labels of series, axis or other components since v3.7. Which supports:</p>
+<ul>
+<li>Box styles (background, border, shadow, etc.), rotation, position of a text block can be specified.</li>
+<li>Styles (color, font, width/height, background, shadow, etc.) and alignment can be customzied on fragments of text.</li>
+<li>Image can be used in text as icon or background.</li>
+<li>Combine these configurations, some special effects can be made, such as simple table, horizontal rule (hr).</li>
+</ul>
+<p>At the beginning, the meanings of two terms that will be used below should be clarified:</p>
+<ul>
+<li>Text Block: The whole block of label text.</li>
+<li>Text fragment: Some piece of text in a text block.</li>
+</ul>
+<p>For example:</p>
+<iframe width="400" height="300" src="https://echarts.apache.org/examples/en/view.html?c=doc-example/text-block-fragment"></iframe>
+<h2 id="options-about-text"><a href="#options-about-text" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Options about Text</h2>
+<p>echarts provides plenty of text options, including:</p>
+<ul>
+<li>Basic font style: <code>fontStyle</code>, <code>fontWeight</code>, <code>fontSize</code>, <code>fontFamily</code>.</li>
+<li>Fill of text: <code>color</code>.</li>
+<li>Stroke of text: <code>textBorderColor</code>, <code>textBorderWidth</code>.</li>
+<li>Shadow of text: <code>textShadowColor</code>, <code>textShadowBlur</code>, <code>textShadowOffsetX</code>, <code>textShadowOffsetY</code>.</li>
+<li>Box size of text block or text fragment: <code>lineHeight</code>, <code>width</code>, <code>height</code>, <code>padding</code>.</li>
+<li>Alignment of text block or text fragment: <code>align</code>, <code>verticalAlign</code>.</li>
+<li>Border, background (color or image) of text block or text fragment: <code>backgroundColor</code>, <code>borderColor</code>, <code>borderWidth</code>, <code>borderRadius</code>.</li>
+<li>Shadow of text block or text fragment: <code>shadowColor</code>, <code>shadowBlur</code>, <code>shadowOffsetX</code>, <code>shadowOffsetY</code>.</li>
+<li>Position and rotation of text block: <code>position</code>, <code>distance</code>, <code>rotate</code>.</li>
+</ul>
+<p>User can defined styles for text fragment in <code>rich</code> property. For example, <a href="option.html#series-bar.label.rich">series-bar.label.rich</a></p>
+<p>For example:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<blockquote>
+<p>Notice: <code>width</code> 和 <code>height</code> only work when <code>rich</code> specified.</p>
+</blockquote>
+<h2 id="basic-styles-of-text-text-block-and-text-fragment"><a href="#basic-styles-of-text-text-block-and-text-fragment" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Basic Styles of Text, Text Block and Text Fragment</h2>
+<p>Basic font style can be set to text: <code>fontStyle</code>, <code>fontWeight</code>, <code>fontSize</code>, <code>fontFamily</code>.</p>
+<p>Fill color and stroke color can be set to text: <code>color</code>, <code>textBorderColor</code>, <code>textBorderWidth</code>.</p>
+<p>Border style and background style can be set to text block: <code>borderColor</code>, <code>borderWidth</code>, <code>backgroundColor</code>, <code>padding</code>.</p>
+<p>Border style and background style can be set to text fragment too: <code>borderColor</code>, <code>borderWidth</code>, <code>backgroundColor</code>, <code>padding</code>.</p>
+<p>For example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="label-position"><a href="#label-position" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Label Position</h2>
+<p><code>label</code> option can be use in charts like <code>bar</code>, <code>line</code>, <code>scatter</code>, etc. The position of a label, can be specified by <a href="option.html#series-scatter.label.position">label.position</a>、<a href="option.html#series-scatter.label.distance">label.distance</a>.</p>
+<p>Try to modify the <code>position</code> and <code>distance</code> option in the following example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<blockquote>
+<p>Notice, there are different optional values of <code>position</code> by different chart types. And <code>distance</code> is not supported in every chart. More detailed info can be checked in <a href="https://echarts.apache.org/option.html" rel="nofollow noopener noreferrer" target="_blank">option doc</a>.</p>
+</blockquote>
+<h2 id="label-rotation"><a href="#label-rotation" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Label Rotation</h2>
+<p>Sometimes label is needed to be rotated. For example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p><a href="option.html#series-bar.label.align">align</a> and<a href="option.html#series-bar.label.verticalAlign">verticalAlign</a> can be used to adjust location of label in this scenario.</p>
+<p>Notice, <code>align</code> and <code>verticalAlign</code> are applied firstly, then rotate.</p>
+<h2 id="layout-and-alignment-of-text-fragment"><a href="#layout-and-alignment-of-text-fragment" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Layout and Alignment of Text fragment</h2>
+<p>To understand the layout rule, every text fragment can be imagined as a <code>inline-block</code> dom element in CSS.</p>
+<p><code>content box size</code> of a text fragment is determined by its font size by default. It can also be specified directly by <code>width</code> and <code>height</code>, although they are rarely set. <code>border box size</code> of a text fragment is calculated by adding the <code>border box size</code> and <code>padding</code>.</p>
+<p>Only <code>'\n'</code> is the newline character, which breaks a line.</p>
+<p>Multiple text fragment exist in a single line. The height of a line is determined by the biggest <code>lineHeight</code> of text fragments. <code>lineHeight</code> of a text fragment can be specified in <code>rich</code>, or in the parent level of <code>rich</code>, otherwise using <code>box size</code> of the text fragment.</p>
+<p>Having <code>lineHeight</code> determined, the vertical position of text fragments can be determined by <code>verticalAlign</code> (there is a little different from the rule in CSS):</p>
+<ul>
+<li><code>'bottom'</code>: The bottom edge of the text fragment sticks to the bottom edge of the line.</li>
+<li><code>'top'</code>: The top edge of the text fragment sticks to the top edge of the line.</li>
+<li><code>'middle'</code>: In the middle of the line.</li>
+</ul>
+<p>The width of a text block can be specified by <code>width</code>, otherwise, by the longest line. Having the width determined, text fragment can be placed in each line, where the horizontal position of text fragments can be determined by its <code>align</code>.</p>
+<ul>
+<li>Firstly, place text fragments whose <code>align</code> is <code>'left'</code> from left to right continuously.</li>
+<li>Secondly, place text fragments whose <code>align</code> is <code>'right'</code> from right to left continuously.</li>
+<li>Finally, the text fragments remained will be sticked and placed in the center of the rest of space.</li>
+</ul>
+<p>The position of text in a text fragment:</p>
+<ul>
+<li>If <code>align</code> is <code>'center'</code>, text aligns at the center of the text fragment box.</li>
+<li>If <code>align</code> is <code>'left'</code>, text aligns at the left of the text fragment box.</li>
+<li>If <code>align</code> is <code>'right'</code>, text aligns at the right of the text fragment box.</li>
+</ul>

+<p>See example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>Icon is implemented by using image in <code>backgroundColor</code>.</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>Horizontal rule (like HTML <hr> tag) can be implemented by border:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>Title block can be implemented by <code>backgroundColor</code>:</p>

+<p>Note that in order to keep the size of the package to a minimum, ECharts does not provide any renderer in tree-shakeable interface, so you need to choose to import <code>CanvasRenderer</code> or <code>SVGRenderer</code> as the renderer. The advantage of this is that if you only need to use the svg rendering mode, the bundle will not include the <code>CanvasRenderer</code> module, which is not needed.</p>

+<p>Data visualization has come a long way in the last few years. Developers no longer expect visualization products to be simple chart creation tools, but have more advanced needs in terms of interaction, performance, data processing, and more.</p>
+<p>Apache ECharts has always been committed to making it easier for developers to create flexible and rich visualizations. In the latest release of Apache ECharts 5, we have focused on enhancing the storytelling of charts, allowing developers to tell the story behind the data in a simpler way.</p>
+<img src="images/feature-v5/echarts-5-en.png" width="800px">
+<p>"The core of Apache ECharts 5 is "Show, do not tell", which is a comprehensive upgrade of five topics and 15 features around the stroy telling of visualizations, allowing charts to better tell the story behind the data. It helps developers to create visualizations that meet the needs of various scenarios more easily.</p>
+<h2 id="storytelling"><a href="#storytelling" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Storytelling</h2>
+<p>The importance of animation to human cognition cannot be overstated. In our previous work, we used initialization animations and transition animations to help users understand the connection between data transformations, making the appearance of charts and transformations seem less rigid. This time, we have even enhanced our animation capabilities, even more significantly. We hope to further exploit the role of animation to help users' cognition, and help them understand the story beh [...]
+<h4 id="barline-racing"><a href="#barline-racing" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Bar/Line Racing</h4>
+<p>Apache ECharts 5 adds support for dynamically sorted bar-racing and dynamically sorted line-racing charts to help developers easily create time-series charts that show changes in data over time and tell the evolution of data.</p>
+<iframe width="700" height="400" src="https://echarts.apache.org/examples/en/view.html?c=bar-race-country"></iframe>
+
+
+<iframe width="700" height="400" src="https://echarts.apache.org/examples/en/view.html?c=line-race"></iframe>
+<p>The dynamic sorting chart shows the derivation of different categories in the ranking over time. The developer can enable this effect in ECharts with a few simple configuration code.</p>
+<h4 id="custom-series-animation"><a href="#custom-series-animation" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Custom Series Animation</h4>
+<p>In addition to dynamic sorting charts, Apache ECharts 5 provides even richer and more powerful animations in the custom series, supporting interpolation animations for label value text, transition animations for morph, combine, separate, and other effects of graphics.</p>
+<p>Imagine what amazing visualizations you can create with these dynamic effects!</p>
+<h2 id="visual-design"><a href="#visual-design" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Visual Design</h2>
+<p>The role of visual design is not only to make the chart look better, but more importantly, a design that conforms to the principles of visualization can help users understand more quickly what the chart is trying to say and eliminate as much misunderstanding as possible from poor design.</p>
+<h4 id="overall-design"><a href="#overall-design" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Overall Design</h4>
+<p>We have found that a large percentage of developers use the default theme style for ECharts, so it is important to have an elegant default theme design. In Apache ECharts 5, we redesigned the default theme style, optimizing it for different charts and components. For example, we took into account factors such as differentiation between colors, contrast with background colors, and harmony with adjacent colors, and ensured that people with color blindness could clearly distinguish data.</p>
+<img src="images/feature-v5/theme-color.png" width="400px">
+<p>Let's look at the new version of the light and dark theme styles using the most commonly used bar chart as an example.</p>
+<img src="images/feature-v5/new-theme-light.png" width="500px">
+<img src="images/feature-v5/new-theme-dark.png" width="500px">
+<p>For the data area zoom, timeline and other interactive components, we also designed a new style and provide a better interactive experience:</p>
+<img src="images/feature-v5/dataZoom.png" width="500px">
+<img src="images/feature-v5/timeline.png" width="500px">
+<h4 id="label"><a href="#label" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Label</h4>
+<p>Labels are one of the core elements of a chart, and clear and unambiguous labels help users to have a more accurate understanding of the data. Apache ECharts 5 provides a variety of new labeling features that allow dense labels to be clearly displayed and accurately represented.</p>
+<p>Apache ECharts 5 can be enabled to automatically hide overlapping labels through a configuration item. For labels that exceed the display area, you can choose to automatically truncate or line break them. Dense pie chart labels now have a more aesthetically pleasing automatic layout.</p>
+<p>These features can help avoid text that is too dense and affects readability. And, no additional code needs to be written by the developer for them to take effect by default, greatly simplifying the development cost for developers.</p>
+<p>We also provide several configuration options to allow developers to actively control the layout strategy of tabs, such as tab dragging, overall display at the edge of the canvas, connecting with guide lines and graphical elements, and still linking to highlight the associated relationships.</p>
+<p>The new label feature allows you to have very clear label presentation even in a confined space mobile:</p>
+<img src="images/feature-v5/pie-label.png" width="400px">
+<h4 id="time-axis"><a href="#time-axis" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Time Axis</h4>
+<p>Apache ECharts 5 brings a time axis suitable for expressing timestamp scales. The default design of the time axis highlights important information more prominently and provides more flexible customization capabilities, allowing developers to tailor the time axis's label content to different needs.</p>
+<p>First of all, the time axis is no longer split absolutely evenly as before, but instead selects more meaningful points like year, month, day, and whole point to display, and can show different levels of scales at the same time. The <code>formatter</code> of labels supports templates for time (e.g. <code>{yyyy}-{MM}-{dd}</code>), and different <code>formatter</code> can be specified for labels with different time granularity, which can be combined with rich text labels to create eye-ca [...]

+<h4 id="tooltip"><a href="#tooltip" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Tooltip</h4>
+<p>Tooltip is one of the most commonly used visualization components to help users interactively understand the details of data. In Apache ECharts 5, we have optimized the style of the tooltip, making the default display of the tooltip elegant and clear by adjusting the font style, color, arrow pointing to the graph, border color following the graph color, and other features. The rendering logic of rich text has been improved to ensure that the display is consistent with the HTML way, al [...]
+<img src="images/feature-v5/new-tooltip.png" width="400px">
+<img src="images/feature-v5/new-tooltip-2.png" width="400px">
+<p>In addition to this, we have also added the ability to sort the list in the tip box by value size or category order this time.</p>
+<h4 id="gauge"><a href="#gauge" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Gauge</h4>
+<p>We have seen a lot of cool gauge charts created by community users, but the way they are configured is often complex and tricky. Therefore, we have upgraded the gauge to support image or vector path drawing pointers, anchor configurations, progress bars, rounded corner effects, and more.</p>
+<p>Different styles of gauge pointers.</p>
+<img src="images/feature-v5/gauge-pointer.png" width="600px">
+<p>These upgrades not only allow developers to achieve cool effects with simpler configuration items, but also bring richer customization capabilities.</p>
+<iframe width="600" height="600" src="https://echarts.apache.org/examples/en/view.html?c=gauge-clock"></iframe>
+<h4 id="round-corner"><a href="#round-corner" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Round Corner</h4>
+<p>Apache ECharts 5 supports round corner for pie charts, sunburst charts, and treemap charts. Don't underestimate the simplicity of the rounded corners configuration, but combine them with other effects to create a more personalized visualization.</p>
+<iframe width="400" height="400" src="https://echarts.apache.org/examples/en/view.html?c=sunburst-borderRadius"></iframe>
+<h2 id="interactivity"><a href="#interactivity" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Interactivity</h2>
+<p>The interactivity of the visualization helps users explore the work and deepen their understanding of the main idea of the diagram.</p>
+<h4 id="multi-state"><a href="#multi-state" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Multi-State</h4>
+<p>In ECharts 4, there were two interactive states, <code>emphasis</code> and <code>normal</code>, graph will enter the <code>emphasis</code> state when the mouse hovered to distinguish the data.</p>
+<p>This time in Apache ECharts 5, we have added a new effect of <strong>blur</strong> other non-related elements to the original mouse hover highlighting, so that the target data can be focused.</p>
+<p>For example, in this <a href="https://echarts.apache.org/examples/en/editor.html?c=bar-y-category-stack" rel="nofollow noopener noreferrer" target="_blank">bar chart</a> example, when the mouse hovers over a series, other non-related series will fade out, thus highlighting more clearly the comparison of data in the focused series. of data in the comparison. On diagrams with more complex data structures such as relationship, tree, sunburst, sankey, etc., it is also possible to see the [...]
+<p>In addition, we've added <strong>click to select</strong> to all series, an interaction that was previously only available in a few series such as pie charts and maps, allowing developers to set it to single or multiple selection mode, and to listen to the <code>selectchanged</code> event to get all the selected shapes for further processing. As with <code>emphasis</code> and <code>blur</code>, the selection style can also be configured in <code>select</code>.</p>

+<h5 id="dirty-rectangle-rendering"><a href="#dirty-rectangle-rendering" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Dirty Rectangle Rendering</h5>
+<p>Apache ECharts 5 has new support for dirty rectangle rendering to address performance bottlenecks in large scenes with only local changes. When using the Canvas renderer, the dirty rectangle rendering technique detects and updates only the parts of the view that have changed, rather than any changes causing a complete redraw of the canvas. This can help improve rendering frame rates in some special scenarios, such as scenes where the mouse frequently triggers some graphical highlighti [...]

+<p>You can see the effect by enable dirty rectangle optimization on the new example page.</p>
+<h5 id="line-chart-performance-optimization-for-real-time-time-series-data"><a href="#line-chart-performance-optimization-for-real-time-time-series-data" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Line Chart Performance Optimization for Real-Time Time-Series Data</h5>
+<p>In addition, the performance of line graphs with large amounts of data has also seen a significant performance improvement. We often encounter the need for high-performance plotting of large amounts of real-time time-series data, which will be updated every hundreds or tens of milliseconds.</p>
+<p>Apache ECharts 5 deeply optimizes CPU consumption, memory usage, and initialization time in these scenarios, enabling real-time updates (less than 30ms per update) for millions of data, and even rendering within 1s for ten millions of data, with low memory usage and smooth tooltip interactions.</p>
+<h2 id="development-experience"><a href="#development-experience" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Development Experience</h2>
+<p>We want such a powerful visualization tool to be used by more developers in a simpler way, so the developer experience is also a very important aspect for us.</p>
+<h4 id="datasets"><a href="#datasets" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Datasets</h4>
+<p>ECharts 5 enhances the data transformation capabilities of datasets, allowing developers to implement common data processing such as filtering, sorting, aggregating, histogram, simple clustering, regression, etc. in a simple way. Developers can use these functions in a uniform and declarative way, and can easily implement common data operations.</p>
+<h4 id="internationalization"><a href="#internationalization" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Internationalization</h4>
+<p>The original internationalization implementation of ECharts takes the form of different distribution files packaged according to different language parameters. In this way, the dynamic language and main code are bound together, and the only way to switch languages when using ECharts is to reload different language versions of ECharts distributions.</p>
+<p>Therefore, starting with Apache ECharts 5, the dynamic language is separated from the main code. To switch languages, you only need to load the corresponding language, use the <code>registerLocale</code> function to mount the language object in a similar way to mount the theme, and then reinitialize it to complete the language switch.</p>

+<h4 id="typescript-refactoring"><a href="#typescript-refactoring" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>TypeScript Refactoring</h4>
+<p>In order to continue to refactor and develop new features more safely and efficiently, we started the development of Apache ECharts 5 by rewriting the code using TypeScript. The strong typing brought by TypeScript gave us the confidence to refactor the code drastically to achieve more exciting features during the development of ECharts 5.</p>
+<p>For developers, we can also generate better and more code-compliant <code>DTS</code> type description files directly from TypeScript code. Until now, ECharts type description files have been maintained by community developers and published to <a href="https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/echarts" rel="nofollow noopener noreferrer" target="_blank">DefinityTyped</a>, which is a lot of work, so thanks for your contribution.</p>
+<p>In addition, if a developer's component is introduced on-demand, we provide a <code>ComposeOption</code> type method that can combine a configuration item type that contains only the introduced components, which can bring stricter type checking and help you detect unintroduced component types in advance.</p>
+<h2 id="accessibility"><a href="#accessibility" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Accessibility</h2>
+<p>Apache ECharts has always taken accessibility design seriously, and we want to make the information conveyed by charts equally to be accessed. We also want to make this possible for chart developers at a very low development cost, thus making developers more willing to support the accessibility.</p>
+<p>In the last major release, we supported automatic intelligent generation of chart descriptions based on different chart types and data, making it very easy for developers to support DOM description information for charts. In ECharts 5, we have also made more accessibility improvements to help people with visual impairments better understand the chart content.</p>
+<h4 id="theme-colors"><a href="#theme-colors" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Theme Colors</h4>
+<p>We took accessibility into account when designing the new default theme, and we repeatedly tested the brightness and color values of the colors to help accessibility users clearly identify the chart data.</p>
+<p>Moreover, for developers with further accessibility needs, we also provide special high-contrast themes to further differentiate the data with higher contrast colors.</p>
+<h4 id="decal-patterns"><a href="#decal-patterns" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Decal Patterns</h4>
+<p>ECharts 5 also provides a new feature of decals to help users further differentiate data by using patterns to assist with color representation.</p>
+<iframe width="600" height="350" src="https://echarts.apache.org/examples/en/view.html?c=doc-example/aria-decal-simple"></iframe>
+<p>In addition, decal patterns can also help in some other scenarios, such as: helping to better distinguish data in printed materials like newspapers and books that have only a single color or very few colors; using graphical elements to facilitate a more intuitive understanding of the data by the user.</p>
+<iframe width="600" height="350" src="https://echarts.apache.org/examples/en/view.html?c=doc-example/aria-decal-newspaper"></iframe>
+<h2 id="summary"><a href="#summary" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Summary</h2>
+<p>In addition to the features described above, Apache ECharts has been improved in a very large number of details to help developers more easily create charts that good by default, are flexible in configuration, and tell the story behind the data with charts.</p>
+<p>Thank you to all the developers who have used ECharts, and even participated in community contributions, for making Apache ECharts 5 possible. We'll be working on future developments with even more enthusiasm, and we'll see you all in 6 with even more enthusiasm!</p></div> <div class="table-of-contents"><h4 class="toc-container-header">In This Page</h4> <ul><li class="toc2"><a href="/echarts-handbook/en/basics/release-note/v5-feature#storytelling">Storytelling</a></li><li class="toc2" [...]

+<p>This guide is for those who want to upgrade from echarts 4.x (hereafter <code>v4</code>) to echarts 5.x (hereafter <code>v5</code>). You can find out what new features <code>v5</code> brings that are worth upgrading in <a href="en/basics/release-note/v5-feature">New Features in ECharts 5</a>. In most cases, developers won't need to do anything extra for this upgrade, as echarts has always tried to keep the API as stable and backward-compatible as possible.

+<p>To make it easier for you to know which modules you need to import based on your option, our new example page adds a new feature to generate the three-shakable code, you can check the <code>Full Code</code> tab on the example page to see the modules you need to introduce and the related code.</p>
+<p>In most cases, we recommend using the new tree-shaking interface whenever possible, as it maximizes the power of the packaging tool tree-shaking and effectively resolves namespace conflicts and prevents the exposure of internal structures. If you are still using the CommonJS method of writing modules, the previous approach is still supported:</p>

+<blockquote>
+<p>Note: This section is only for developers who use tree-shaking interfaces to ensure a minimal bundle size, not for those who imports the whole package.</p>

+<p>In order to keep the size of the bundle small enough, we remove some dependencies that would have been imported by default. For example, as mentioned above, when using the new on-demand interface, <code>CanvasRenderer</code> is no longer introduced by default, which ensures that unneeded Canvas rendering code is not imported when only SVG rendering mode is used, and in addition, the following dependencies are adjusted.</p>

Users can <strong>keep using these deprecated API</strong>, with only some warning will be printed to console in dev mode. But if users have spare time, it is recommended to upgraded to new API for the consideration of long term maintenance.</p>
+<p>The deprecated API and their corresponding new API are listed as follows:</p>
+<ul>
+<li>Transform related props of a graphic element are changed:
+<ul>
+<li>Changes:
+<ul>
+<li><code>position: [number, number]</code> are changed to <code>x: number</code>/<code>y: number</code>.</li>

+<li>textShadowOffsetX</li>
+<li>textShadowOffsetY</li>
+</ul>
+</li>
+</ul>
+</li>
+<li>It effects these places:
+<ul>
+<li>In the <code>graphic</code> components: the declarations of each element. [compat, but not accurately the same in some complicated cases.]</li>
+<li>In <code>custom series</code>: the declarations of each element in the return of <code>renderItem</code>. [compat, but not accurately the same in some complicated cases].</li>

+<p>Most of the browser-side chart libraries are using SVG or Canvas as their underlying render because they are interchangeable. However, they show notable differences in some specific scenarios and cases. As a result, it is hard to find a standard choice between them.</p>
+<p>Canvas has been used as the renderer (VML for IE8-) of ECharts from the beginning. Since <a href="https://github.com/apache/echarts/releases" rel="nofollow noopener noreferrer" target="_blank">ECharts v4.0</a> was released, ECharts provided the SVG render as an additional option. You can specify the <a href="http://echarts.baidu.com/api.html#echarts.init" rel="nofollow noopener noreferrer" target="_blank">renderer parameter</a> as <code>'canvas'</code> or <code>'svg'</code> while init [...]
+<blockquote>
+<p>SVG and Canvas have a significant difference in use. The simultaneous transparent support in ECharts between SVG and Canvas is because of the abstraction and implementation of the underlying library <a href="https://github.com/ecomfe/zrender" rel="nofollow noopener noreferrer" target="_blank">ZRender</a>. It formed an interchangeable SVG renderer and Canvas renderer.</p>
+</blockquote>
+<h2 id="how-to-choose-a-renderer"><a href="#how-to-choose-a-renderer" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>How to Choose a Renderer?</h2>
+<p>Generally, Canvas is more suitable for charts with a large number of elements (heat map, large-scale line or scatter plot in geo or parallel coordinates, etc.), and with visual <a href="https://echarts.apache.org//examples/editor.html?c=lines-bmap-effect" rel="nofollow noopener noreferrer" target="_blank">effect</a>. However, SVG has an important advantage: It has less memory usage (which is important for mobile devices), no blur when using the browser zoom.</p>
+<p>The choice of renderer can be based on a combination of hardware and software environment, data volume and functional requirements.</p>
+<ul>
+<li>In scenarios where the hardware and software environment is good and the amount of data is not too large, both renderers will work and there is not much need to agonise over them.</li>
+<li>In scenarios where the environment is poor and performance issues arise that require optimisation, experimentation can be used to determine which renderer to use. For example, there are these experiences.
+<ul>
+<li>In situations where many instances of ECharts have to be created and the browser is prone to crashing (probably because the number of Canvas is causing the memory footprint to exceed the phone's capacity), the SVG renderer can be used to make improvements. Roughly speaking, the SVG renderer may work better if the chart is running on a low-end Android, or if we are using specific charts such as the <a href="https://ecomfe.github.io/echarts-liquidfill/example/" rel="nofollow noopener n [...]
+<li>For larger amounts of data (>1k is an experience value), canvas renderer is always recommended.</li>
+</ul>
+</li>
+</ul>
+<p>We strongly welcome <a href="https://github.com/apache/echarts/issues/new" rel="nofollow noopener noreferrer" target="_blank">feedback</a> from developers on their experiences and scenarios to help us make better optimizations.</p>
+<p>Note: Currently, some special rendering still relies on Canvas: e.g. <a href="https://echarts.apache.org/option.html#series-lines.effect" rel="nofollow noopener noreferrer" target="_blank">trail effect</a>, <a href="https://echarts.apache.org//examples/editor.html?c=heatmap-bmap" rel="nofollow noopener noreferrer" target="_blank">heatmap with blending effect</a>, etc.</p>
+<h2 id="how-to-use-the-renderer"><a href="#how-to-use-the-renderer" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>How to Use the Renderer</h2>
+<p>If <code>echarts</code> is fully imported in the following way, the code already contains an SVG renderer and a Canvas renderer</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>If you are using treeshakable import as described in <a href="en/basics/import">Introducing Apache ECharts in your project</a>, you will need to import the required renderers manually</p>

+<p>In general, you need to define a <code><div></code> node and use the CSS to change the width and height. While initializing, import the chart into the node. Without declaring <code>opts.width</code> or <code>opts.height</code>, the size of the chart will default to the size of the node.</p>

+<p><code>Data transform</code> has been supported since Apache ECharts<sup>TM</sup> 5. In echarts, the term <code>data transform</code> means that generate new data from user provided source data and transform functions. both This feature is enable users to process data in declarative way, and provides users some common "transform functions" to make that kind of tasks "out-of-the-box". (For consistency in the context, the noun form of the word we keep using the "transform" rather than "t [...]
+<p>The abstract formula of data transform is: <code>outData = f(inputData)</code>, where the transform function <code>f</code> can be like <code>filter</code>, <code>sort</code>, <code>regression</code>, <code>boxplot</code>, <code>cluster</code>, <code>aggregate</code>(todo) ...
+With the help of those transform methods, users can be implements the features like:</p>
+<ul>
+<li>Partition data into multiple series.</li>
+<li>Make some statistics and visualize the result.</li>
+<li>Adapt some visualization algorithms to data and display the result.</li>
+<li>Sort data.</li>
+<li>Remove or choose some kind of empty or special datums.</li>
+<li>...</li>
+</ul>
+<h2 id="get-started-to-data-transform"><a href="#get-started-to-data-transform" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Get Started to Data Transform</h2>
+<p>In echarts, data transform is implemented based on the concept of <a href="~https://echarts.apache.org/option.html##dataset">dataset</a>. A <a href="https://echarts.apache.org/option.html##dataset.transform" rel="nofollow noopener noreferrer" target="_blank">dataset.transform</a> can be configured in a dataset instance to indicate that this dataset is to be generated from this <code>transform</code>. For example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>Let's summarize the key points of using data transform:</p>
+<ul>
+<li>Generate new data from existing declared data via the declaration of <code>transform</code>, <code>fromDatasetIndex</code>/<code>fromDatasetId</code> in some blank dataset.</li>
+<li>Series references these datasets to show the result.</li>
+</ul>
+<h2 id="advanced-usage"><a href="#advanced-usage" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Advanced Usage</h2>
+<h4 id="piped-transform"><a href="#piped-transform" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Piped Transform</h4>
+<p>There is a syntactic sugar that pipe transforms like:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<blockquote>
+<p>Note: theoretically any type of transform is able to have multiple input data and multiple output data. But when a transform is piped, it is only able to take one input (except it is the first transform of the pipe) and product one output (except it is the last transform of the pipe).</p>
+</blockquote>
+<h4 id="output-multiple-data"><a href="#output-multiple-data" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Output Multiple Data</h4>
+<p>In most cases, transform functions only need to produce one data. But there is indeed scenarios that a transform function needs to produce multiple data, each of whom might be used by different series.</p>
+<p>For example, in the built-in boxplot transform, besides boxplot data produced, the outlier data are also produced, which can be used in a scatter series. See the <a href="https://echarts.apache.org/examples/en/editor.html?c=boxplot-light-velocity" rel="nofollow noopener noreferrer" target="_blank">example</a>.</p>
+<p>We use prop <a href="https://echarts.apache.org/option.html##dataset.fromTransformResult" rel="nofollow noopener noreferrer" target="_blank">dataset.fromTransformResult</a> to satisfy this requirement. For example:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>What more, <a href="https://echarts.apache.org/option.html##dataset.fromTransformResult" rel="nofollow noopener noreferrer" target="_blank">dataset.fromTransformResult</a> and <a href="https://echarts.apache.org/option.html##dataset.transform" rel="nofollow noopener noreferrer" target="_blank">dataset.transform</a> can both appear in one dataset, which means that the input of the transform is from retrieved from the upstream result specified by <code>fromTransformResult</code>.

+<p>When using data transform, we might run into the trouble that the final chart do not display correctly but we do not know where the config is wrong. There is a property <code>transform.print</code> might help in such case. (<code>transform.print</code> is only available in dev environment).</p>

+<h2 id="filter-transform"><a href="#filter-transform" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Filter Transform</h2>
+<p>Transform type "filter" is a built-in transform that provide data filter according to specified conditions. The basic option is like:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>This is another example of filter transform:</p>
+<iframe width="100%" height="350" src="https://echarts.apache.org/examples/en/view.html?c=data-transform-filter"></iframe>
+<p><strong>About dimension:</strong></p>
+<p>The <code>config.dimension</code> can be:</p>
+<ul>
+<li>Dimension name declared in dataset, like <code>config: { dimension: 'Year', '=': 2011 }</code>. Dimension name declaration is not mandatory.</li>
+<li>Dimension index (start from 0), like <code>config: { dimension: 3, '=': 2011 }</code>.</li>
+</ul>
+<p><strong>About relational operator:</strong></p>
+<p>The relational operator can be:
+<code>></code>(<code>gt</code>), <code>>=</code>(<code>gte</code>), <code><</code>(<code>lt</code>), <code><=</code>(<code>lte</code>), <code>=</code>(<code>eq</code>), <code>!=</code>(<code>ne</code>, <code><></code>), <code>reg</code>. (The name in the parentheses are aliases). They follows the common semantics.
+Besides the common number comparison, there is some extra features:</p>
+<ul>
+<li>Multiple operators are able to appear in one {} item like <code>{ dimension: 'Price', '>=': 20, '<': 30 }</code>, which means logical "and" (Price >= 20 and Price < 30).</li>
+<li>The data value can be "numeric string". Numeric string is a string that can be converted to number. Like ' 123 '. White spaces and line breaks will be auto trimmed in the conversion.</li>
+<li>If we need to compare "JS <code>Date</code> instance" or date string (like '2012-05-12'), we need to specify <code>parser: 'time'</code> manually, like <code>config: { dimension: 3, lt: '2012-05-12', parser: 'time' }</code>.</li>
+<li>Pure string comparison is supported but can only be used in <code>=</code>, <code>!=</code>. <code>></code>, <code>>=</code>, <code><</code>, <code><=</code> do not support pure string comparison (the "right value" of the four operators can not be a "string").</li>
+<li>The operator <code>reg</code> can be used to make regular expression test. Like using <code>{ dimension: 'Name', reg: /\s+Müller\s*$/ }</code> to select all data items that the "Name" dimension contains family name Müller.</li>
+</ul>
+<p><strong>About logical relationship:</strong></p>
+<p>Sometimes we also need to express logical relationship ( <code>and</code> / <code>or</code> / <code>not</code> ):</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]

+<p><strong>About parser:</strong></p>
+<p>Some "parser" can be specified when make value comparison. At present only supported:</p>
+<ul>
+<li><code>parser: 'time'</code>: Parse the value to date time before comparing. The parser rule is the same as <code>echarts.time.parse</code>, where JS <code>Date</code> instance, timestamp number (in millisecond) and time string (like <code>'2012-05-12 03:11:22'</code>) are supported to be parse to timestamp number, while other value will be parsed to <code>NaN</code>.</li>
+<li><code>parser: 'trim'</code>: Trim the string before making comparison. For non-string, return the original value.</li>
+<li><code>parser: 'number'</code>: Force to convert the value to number before making comparison. If not possible to be converted to a meaningful number, converted to <code>NaN</code>. In most cases it is not necessary, because by default the value will be auto converted to number if possible before making comparison. But the default conversion is strict while this parser provide a loose strategy. If we meet the case that number string with unit suffix (like <code>'33%'</code>, <code>12p [...]

+<li>By default "numeric" (that is, number and numeric-string like <code>' 123 '</code>) are able to sorted by numeric order.</li>
+<li>Otherwise "non-numeric-string" are also able to be ordered among themselves. This might help to the case like grouping data items with the same tag, especially when multiple dimensions participated in the sort (See example below).</li>
+<li>When "numeric" is compared with "non-numeric-string", or either of them is compared with other types of value, they are not comparable. So we call the latter one as "incomparable" and treat it as "min value" or "max value" according to the prop <code>incomparable: 'min' | 'max'</code>. This feature usually helps to decide whether to put the empty values (like <code>null</code>, <code>undefined</code>, <code>NaN</code>, <code>''</code>, <code>'-'</code>) or other illegal values to the [...]
+</ul>
+</li>
+<li><code>filter: 'time' | 'trim' | 'number'</code> can be used, the same as "filter transform".
+<ul>
+<li>If intending to sort time values (JS <code>Date</code> instance or time string like <code>'2012-03-12 11:13:54'</code>), <code>parser: 'time'</code> should be specified. Like <code>config: { dimension: 'date', order: 'desc', parser: 'time' }</code></li>
+<li>If intending to sort values with unit suffix (like <code>'33%'</code>, <code>'16px'</code>), need to use <code>parser: 'number'</code>.</li>

+<p><code>dataset</code> is a component dedicated to manage data. Although you can set the data in <code>series.data</code> for every series, we recommend you use the <code>dataset</code> to manage the data since ECharts 4 so that the data can be reused by multiple components and convenient for the separation of "data and configs". After all, data is the most common part to be changed while other configurations will mostly not change at runtime.</p>
+<h2 id="define-data-under-series"><a href="#define-data-under-series" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Define <code>data</code> under <code>series</code></h2>
+<p>If data is defined under <code>series</code>, for example:</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>Define <code>data</code> under <code>series</code> is suitable for customization for some special data structures such as "tree", "graph" and large data.
+However, it is not conducive to the data sharing for multiple series as well as mapping arrangement of chart types and series based on the original data. The other disadvantage is that programmers always need to divide the data in separate series (and categories) first.</p>
+<h2 id="define-data-in-dataset"><a href="#define-data-in-dataset" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Define <code>data</code> in <code>dataset</code></h2>
+<p>Here are the advantages if you define <code>data</code> in <code>dataset</code>:</p>
+<ul>
+<li>Follow the ideas of data visualization: (I) Provide the data, (II)Mapping from data to visual to become a chart.</li>
+<li>Divide data from other configurations. The data often change but others not. It is
+Easy to manage separately.</li>
+<li>Data can be reused by several series or component, you don't need to create copies of a large amount of data for every series.</li>
+<li>Support more common data format, such as a 2D array, array of classes, etc., to avoid users from converting for data format to a certain extent.</li>
+</ul>
+<p>Here is a simple <code>dataset</code> example:</p>

+<p>The ideas of data visualization: (I) Provide the data, (II)Mapping from data to visual to become a chart.</p>
+<p>In short, you can set these configs of mapping:</p>
+<ul>
+<li>Specify 'column' or 'row' of <code>dataset</code> to map the <code>series</code>. You can use <a href="https://echarts.apache.org/option.html##series.seriesLayoutBy" rel="nofollow noopener noreferrer" target="_blank">series.seriesLayoutBy</a> to configure it. The default is to map according to the column.</li>
+<li>Rule of specifying dimension mapping: how to mapping from dimensions of 'dataset' to <code>axis</code>, <code>tooltip</code>, <code>label</code> and <code>visualMap</code>. To configure the mapping, please use <a href="https://echarts.apache.org/option.html##series.encode" rel="nofollow noopener noreferrer" target="_blank">series.encode</a> and <a href="https://echarts.apache.org/option.html##visualMap" rel="nofollow noopener noreferrer" target="_blank">visualMap</a>.

+<p>After having the dataset, you can configure flexibly: how the data map to the axis and graph series.</p>
+<p>You can use <code>seriesLayoutBy</code> to change the understanding of row and column of the chart. <code>seriesLayoutBy</code> can be:</p>
+<ul>
+<li>'column': Default, the series are placed above the column of <code>dataset</code>.</li>
+<li>'row': The series is placed above the row of <code>dataset</code>.</li>

+<h2 id="dimension"><a href="#dimension" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Dimension</h2>
+<p>Most of the data described in commonly used charts is a "two-dimensional table" structure, in the previous case, we use a 2D array to contain a two-dimensional table. Now, when we map a series to a column, that column was called a "dimension" and each row was called "item", vice versa.</p>
+<p>The dimension can have their name to display in the chart. Dimension name can be defined in the first column (row). In the previous case, <code>'score'</code>, <code>'amount'</code>, <code>'product'</code> are the name of dimensions. The actual data locate from the second row. ECharts will automatically check if the first column (row) contained dimension name in <code>dataset.source</code>. You can also use <code>dataset.sourceHeader: true</code> to declare that the first column (row) [...]
+<p>Try to use single <code>dataset.dimensions</code> or some <code>series.dimensions</code> to define the dimensions, therefore you can specify the name and type together.</p>

+<p>In most cases, you don't need to define the dimension type because the ECharts will automatically judge it. If the judgment is inaccurate, you can define it manually.</p>
+<p>Dimension type can be the following values:</p>
+<ul>
+<li><code>'number'</code>: Default, normal data.</li>
+<li><code>'ordinal'</code>: String types data like categories, text can be used on the axis only with the dimension type 'ordinal'. ECharts will try to judge this type automatically but might be inaccurate, so you can specify manually.</li>
+<li><code>'time'</code>: To represent time data, ECharts can automatically analyze data as timestamp if the dimension type is defined as <code>'time'</code>. For instance, ECharts will auto-analyze if the data of this dimension is '2017-05-10'<code>. If the dimension is used as time axis ([axis.type](https://echarts.apache.org/option.html##xAxis.type) =</code>'time'<code>), the dimension type will also be</code>'time'`.

+<p>After understand the concept of dimension, you can use <a href="https://echarts.apache.org/option.html##series.encode" rel="nofollow noopener noreferrer" target="_blank">series.encode</a> to make a mapping:</p>

+<h2 id="default-seriesencode"><a href="#default-seriesencode" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Default series.encode</h2>
+<p>It is worth mentioning that ECharts will use some default mapping rules for some general charts (line, bar, scatter, candlestick, etc.) if <code>series.encode</code> is not specified. The default rule is:</p>
+<ul>
+<li>In coordinate system (eg. Cartesian, Polar): + If there is category axis (axis.type = 'category'), map the first column(row) to the axis and each subsequent column(row) to each series. + If both axes is not the category, then map every two columns in one series to two axes.</li>
+<li>Without axis (such as Pie Chart): + Use the first column(row) as the name, second column(row) as value. ECharts will not set the name if there is only one column(row).</li>
+</ul>
+<p>While the default rule cannot fulfill the requirements, you can configure <code>encode</code> by yourself, which is not complicate. Here is an <a href="https://echarts.apache.org/examples/en/editor.html?c=dataset-default" rel="nofollow noopener noreferrer" target="_blank">example</a>.</p>

+<p>In most of the normal chart, the data is suitable to be described in the form of a two-dimensional table. That well-known software like 'MS Excel' and 'Numbers' all uses a two-dimensional table. Their data can be exported to JSON format and input to <code>dataset.source</code> and avoid some steps of data processing.</p>

+<p>You can switch .csv file to JSON using tools like <a href="https://github.com/d3/d3-dsv" rel="nofollow noopener noreferrer" target="_blank">dsv</a> or <a href="https://github.com/mholt/PapaParse" rel="nofollow noopener noreferrer" target="_blank">PapaParse</a>.</p>

+<p>ECharts 4 still support the data declaration way in ECharts 3. If the series has already declared the <a href="https://echarts.apache.org/option.html##series.data" rel="nofollow noopener noreferrer" target="_blank">series.data</a>, then use <a href="https://echarts.apache.org/option.html##series.data" rel="nofollow noopener noreferrer" target="_blank">series.data</a> but not <code>dataset</code>.</p>

+<p>You can trigger events such as <code>'legendselectchanged'</code> not only by the user but also with code manually. It can be used to display the tooltip, select the legend.</p>
+<p>In ECharts <code>myChart.dispatchAction({ type: '' })</code> is used to trigger the behavior. This manages all actions and can record the behaviors conveniently.</p>
+<p>Commonly used behavior and corresponding parameters are listed in <a href="https://echarts.apache.org//api.html#action" rel="nofollow noopener noreferrer" target="_blank">action</a>.</p>

+<p>Sometimes developers need to listen to the events that are triggered from the blank of the canvas. For example, need to reset the chart when users click on the blank area.</p>
+<p>Before we talk about this feature, we need to clarify two kinds of events: zrender events and echarts events.</p>

+<p>zrender events are different from echarts events. The former one are triggered when mouse/pointer is at everywhere, while the latter one can only be triggered when mouse/pointer is at the graphic elements. In fact, echarts events are implemented based on zrender events, that is, when a zrender events is triggered at a graphic element, echarts will trigger a echarts event.</p>
+<p>Having zrender events, we can implement listen to events from the blank as follows:</p>

+<p>This article provides an overview of the different approaches about Apache ECharts<sup>TM</sup> style customization. For example, how to config the color, size, shadow of the graphic elements and labels.</p>
+<blockquote>
+<p>The term "style" may not follow the convention of data visualization, but we use it in this article because it is popular and easy to understand.</p>
+</blockquote>
+<p>These approaches below will be introduced. The functionalities of them might be overlapped, but they are suitable for different scenarios.</p>
+<ul>
+<li>Theme</li>
+<li>Color Palette</li>
+<li>Customize style explicitly (itemStyle, lineStyle, areaStyle, label, ...)</li>
+<li>Visual encoding (visualMap component)</li>
+</ul>
+<h2 id="theme"><a href="#theme" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Theme</h2>
+<p>Setting a theme is the simplest way to change the color style. For example, in <a href="$%7BwebsitePath%7D/examples/en/index.html">Examples page</a>, we can switch to dark mode and see the result of a different theme.</p>
+<p>In our project, we can switch to dark theme like:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>Other themes are not included by default, and need to load them ourselves if we want to use them. Themes can be visited and downloaded in the <a href="https://echarts.apache.org/en/theme-builder.html" rel="nofollow noopener noreferrer" target="_blank">theme builder</a>. Theme can also be created or edited in it. The downloaded theme can be used as follows:</p>
+<p>If a theme is downloaded as a JSON file, we should register it by ourselves, for example:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>If a theme is downloaded as a JS file, it will auto register itself:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="color-palette"><a href="#color-palette" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Color Palette</h2>
+<p>Color palette can be given in option. They provide a group of colors, which will be auto picked by series and data. We can give a global palette, or exclusive pallette for certain series.</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="customize-style-explicitly-itemstyle-linestyle-areastyle-label-"><a href="#customize-style-explicitly-itemstyle-linestyle-areastyle-label-" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Customize Style Explicitly (itemStyle, lineStyle, areaStyle, label, ...)</h2>
+<p>It is a common way to set style explicitly. Throughout ECharts <a href="https://echarts.apache.org/option.html#" rel="nofollow noopener noreferrer" target="_blank">option</a>, style related options can be set in various place, including <a href="https://echarts.apache.org/option.html#series.itemStyle" rel="nofollow noopener noreferrer" target="_blank">itemStyle</a>, <a href="https://echarts.apache.org/option.html#series-line.lineStyle" rel="nofollow noopener noreferrer" target="_blank [...]
+<p>Generally speaking, all of the built-in components and series follow the naming convention like <code>itemStyle</code>, <code>lineStyle</code>, <code>areaStyle</code>, <code>label</code> etc, although they may occur in different place according to different series or components.</p>
+<p>In the following code we add shadow, gradient to bubble chart.</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="style-of-emphasis-state"><a href="#style-of-emphasis-state" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Style of Emphasis State</h2>
+<p>When mouse hovering a graphic elements, usually the emphasis style will be displayed. By default, the emphasis style is auto generated by the normal style. However they can be specified by <a href="https://echarts.apache.org/option.html#series-bar.emphasis" rel="nofollow noopener noreferrer" target="_blank">emphasis</a> property. The options in <a href="https://echarts.apache.org/option.html#series-bar.emphasis" rel="nofollow noopener noreferrer" target="_blank">emphasis</a> is the sa [...]
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>Notice: Before ECharts4, the emphasis style should be written like this:</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>The option format is still <strong>compatible</strong>, but not recommended. In fact, in most cases, users only set normal style, and use the default emphasis style. So since ECharts4, we support to write style without the "normal" term, which makes the option more simple and neat.</p>

+<p>Data visualization is a procedure of mapping data into visual elements. This procedure can also be called visual coding, and visual elements can also be called visual channels.</p>
+<p>Every type of charts in Apache ECharts<sup>TM</sup> has this built-in mapping procedure. For example, line chart map data into <em>lines</em>, bar chart map data into <em>height</em>. Some more complicated charts, like <code>graph</code>, <code>themeRiver</code>, and <code>treemap</code> have their own built-in mapping.</p>
+<p>Besides, ECharts provides <a href="https://echarts.apache.org/option.html#visualMap" rel="nofollow noopener noreferrer" target="_blank">visualMap component</a> for general visual mapping. Visual elements allowed in <code>visualMap</code> component are:</p>
+<ul>
+<li><code>symbol</code>, <code>symbolSize</code></li>
+<li><code>color</code>, <code>opacity</code>, <code>colorAlpha</code>,</li>
+<li><code>colorLightness</code>, <code>colorSaturation</code>, <code>colorHue</code></li>
+</ul>
+<p>Next, we are going to introduce how to use <code>visualMap</code> component.</p>
+<h2 id="data-and-dimension"><a href="#data-and-dimension" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Data and Dimension</h2>
+<p>Data are usually stored in <a href="https://echarts.apache.org/option.html#series.data" rel="nofollow noopener noreferrer" target="_blank">series.data</a> in ECharts. Depending on chart types, like list, tree, graph, and so on, the form of data may vary somehow. But they have one common feature, that they are a collection of data items. Every data item contains data value, and other information if needed. Every data value can be a single value (one dimension) or an array (multiple dim [...]
+<p>For example, <a href="https://echarts.apache.org/option.html#series.data" rel="nofollow noopener noreferrer" target="_blank">series.data</a> is the most common form, which is a <code>list</code>, a common array:</p>

+<p>Usually the first one or two dimensions are used for mapping. For example, map the first dimension to x axis, and the second dimension to y axis. If you want to represent more dimensions, <code>visualMap</code> is what you need. Most likely, <a href="https://echarts.apache.org/option.html#series-scatter" rel="nofollow noopener noreferrer" target="_blank">scatter charts</a> use radius to represent the third dimension.</p>
+<h2 id="the-visualmap-component"><a href="#the-visualmap-component" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>The visualMap Component</h2>
+<p>visualMap component defines the mapping from <em>which dimension of data</em> to <em>what visual elements</em>.</p>
+<p>The following two types of visualMap components are supported, identified with <a href="https://echarts.apache.org/option.html#visualMap.type" rel="nofollow noopener noreferrer" target="_blank">visualMap.type</a>.</p>
+<p>Its structure is defined as:</p>

+<p>The visual mapping component of ECharts is divided into continuous (<a href="https://echarts.apache.org/option.html#visualMap-continuous" rel="nofollow noopener noreferrer" target="_blank">visualMapContinuous</a>) and piecewise (<a href="https://echarts.apache.org/option.html#visualMap-piecewise" rel="nofollow noopener noreferrer" target="_blank">visualMapPiecewise</a>).</p>
+<p>Continuous means that the data dimension for visual mapping is a continuous value, while piecewise means that the data is divided into multiple segments or discrete data.</p>
+<h3 id="continuous-visual-mapping"><a href="#continuous-visual-mapping" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Continuous Visual Mapping</h3>

+<h3 id="piecewise-visual-mapping"><a href="#piecewise-visual-mapping" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>Piecewise Visual Mapping</h3>
+<p>The piecewise visual mapping component has three modes.</p>

+<p>柱状图（或称条形图）是一种通过柱形的长度来表现数据大小的一种常用图表类型。</p>
+<p>设置柱状图的方式，是将 <code>series</code> 的 <code>type</code> 设为 <code>'bar'</code>。</p>
+<p><a href="https://echarts.apache.org/option.html#series-bar" rel="nofollow noopener noreferrer" target="_blank">[配置项手册]</a></p>
+<h2 id="最简单的柱状图"><a href="#%E6%9C%80%E7%AE%80%E5%8D%95%E7%9A%84%E6%9F%B1%E7%8A%B6%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>最简单的柱状图</h2>
+<p>最简单的柱状图可以这样设置：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>在这个例子中，横坐标是类目型的，因此需要在 <code>xAxis</code> 中指定对应的值；而纵坐标是数值型的，可以根据 <code>series</code> 中的 <code>data</code>，自动生成对应的坐标范围。</p>
+<h2 id="多系列的柱状图"><a href="#%E5%A4%9A%E7%B3%BB%E5%88%97%E7%9A%84%E6%9F%B1%E7%8A%B6%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>多系列的柱状图</h2>
+<p>我们可以用一个系列表示一组相关的数据，如果需要实现多系列的柱状图，只需要在 <code>series</code> 多添加一项就可以了——</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="柱状图样式设置"><a href="#%E6%9F%B1%E7%8A%B6%E5%9B%BE%E6%A0%B7%E5%BC%8F%E8%AE%BE%E7%BD%AE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>柱状图样式设置</h2>
+<h3 id="柱条样式"><a href="#%E6%9F%B1%E6%9D%A1%E6%A0%B7%E5%BC%8F" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>柱条样式</h3>
+<p>柱条的样式可以通过 <a href="https://echarts.apache.org/option.html#series-bar.itemStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.itemStyle</code></a> 设置，包括：</p>
+<ul>
+<li>柱条的颜色（<code>color</code>）；</li>
+<li>柱条的描边颜色（<code>borderColor</code>）、宽度（<code>borderWidth</code>）、样式（<code>borderType</code>）；</li>
+<li>柱条圆角的半径（<code>barBorderRadius</code>）；</li>
+<li>柱条透明度（<code>opacity</code>）；</li>
+<li>阴影（<code>shadowBlur</code>、<code>shadowColor</code>、<code>shadowOffsetX</code>、<code>shadowOffsetY</code>）。</li>
+</ul>
+<div class="nuxt-content-highlight"><!----></div>
+<p>在这个例子中，我们通过设置柱状图对应 <code>series</code> 的<code>itemStyle</code>，设置了柱条的样式。完整的配置项及其用法请参见配置项手册 <a href="https://echarts.apache.org/option.html#series-bar.itemStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.itemStyle</code></a>。</p>
+<h3 id="柱条宽度和高度"><a href="#%E6%9F%B1%E6%9D%A1%E5%AE%BD%E5%BA%A6%E5%92%8C%E9%AB%98%E5%BA%A6" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>柱条宽度和高度</h3>
+<p>柱条宽度可以通过 <a href="https://echarts.apache.org/option.html##series-bar.barWidth" rel="nofollow noopener noreferrer" target="_blank"><code>barWidth</code></a> 设置。比如在下面的例子中，将 <code>barWidth</code> 设为 <code>'20%'</code>，表示每个柱条的宽度就是类目宽度的 20%。由于这个例子中，每个系列有 5 个数据，20% 的类目宽度也就是整个 x 轴宽度的 4%。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>另外，还可以设置 <a href="https://echarts.apache.org/option.html#series-bar.barMaxWidth" rel="nofollow noopener noreferrer" target="_blank"><code>barMaxWidth</code></a> 限制柱条的最大宽度。对于一些特别小的数据，我们也可以为柱条指定最小高度 <a href="https://echarts.apache.org/option.html#series-bar.barMinHeight" rel="nofollow noopener noreferrer" target="_blank"><code>barMinHeight</code></a>，当数据对应的柱条高度小于该值时，柱条高度将采用这个最小高度。</p>
+<h3 id="柱条间距"><a href="#%E6%9F%B1%E6%9D%A1%E9%97%B4%E8%B7%9D" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>柱条间距</h3>

+<div class="nuxt-content-highlight"><!----></div>
+<p>在这个例子中，<code>barGap</code> 被设为 <code>'20%'</code>，这意味着每个类目（比如 <code>A</code>）下的两个柱子之间的距离，相对于柱条宽度的百分比。而 <code>barCategoryGap</code> 是 <code>'40%'</code>，意味着柱条每侧空余的距离，相对于柱条宽度的百分比。</p>
+<p>通常而言，设置 <code>barGap</code> 及 <code>barCategoryGap</code> 后，就不需要设置 <code>barWidth</code> 了，这时候的宽度会自动调整。如果有需要的话，可以设置 <code>barMaxWidth</code> 作为柱条宽度的上限，当图表宽度很大的时候，柱条宽度也不会太宽。</p>

+<p>有时候，我们不仅希望知道不同系列各自的数值，还希望知道它们之和的变化，这时候通常使用堆积柱状图图来表现。顾名思义，堆积柱状图就是一个系列的数值“堆积”在另一个系列上，因而从他们的高度总和就能表达总量的变化。</p>
+<p>使用 EChart 实现堆积折线图的方法非常简单，只需要给一个系列的 <code>stack</code> 值设置一个字符串类型的值，这一个值表示该系列堆积的类别。也就是说，拥有同样 <code>stack</code> 值的系列将堆积在一组。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>在这个例子中，第二个系列所在的位置是在第一个系列的位置的基础上，上升了第二个系列数值对应的高度。因此，从第二个系列的位置，就能看出这两者总和的变化趋势。</p>
+<blockquote>
+<p><code>stack</code> 的取值用来表明哪些系列将被堆积在一起，理论上只要取值相同即可，具体的取值并没有什么区别。但在实际的应用中，我们建议使用一些有意义的字符串方便阅读。</p>
+<p>比如，在一个统计男女人数的图中，有四个系列，“成年男性”和“男孩”系列需要进行堆积，“成年女性”和“女孩”系列需要堆积。这时，这两组的的 <code>stack</code> 值就建议分别设为 <code>'男'</code> 和 <code>'女'</code>。虽然使用 <code>'a'</code> 和 <code>'b'</code> 这样没有意义的字符串也能实现同样的效果，但是代码的可阅读性就差了。</p>

+<p>柱状图（或称条形图）是一种通过柱形的长度来表现数据大小的一种常用图表类型。</p>
+<h2 id="最简单的折线图"><a href="#%E6%9C%80%E7%AE%80%E5%8D%95%E7%9A%84%E6%8A%98%E7%BA%BF%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>最简单的折线图</h2>
+<p>如果我们想建立一个横坐标是类目型（category）、纵坐标是数值型（value）的折线图，我们可以使用这样的方式：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>在这个例子中，我们通过 <code>xAxis</code> 将横坐标设为类目型，并指定了对应的值；通过 <code>type</code> 将 <code>yAxis</code> 的类型设定为数值型。在 <code>series</code> 中，我们将系列类型设为 <code>line</code>，并且通过 <code>data</code> 指定了折线图三个点的取值。这样，就能得到一个最简单的折线图了。</p>
+<blockquote>
+<p>这里 <code>xAxis</code> 和 <code>yAxis</code> 的 <code>type</code> 属性都可以隐去不写。因为坐标轴的默认类型是数值型，而 <code>xAxis</code> 指定了类目型的 <code>data</code>，所以 <code>ECharts</code> 也能识别出这是类目型的坐标轴。为了让大家更容易理解，我们特意写了 <code>type</code>。在实际的应用中，如果是 <code>'value'</code> 类型，也可以省略不写。</p>

+<p>如果我们希望折线图在横坐标和纵坐标上都是连续的，即在笛卡尔坐标系中，应该如何实现呢？答案也很简单，只要把 <code>series</code> 的 <code>data</code> 每个数据用一个包含两个元素的数组表示就行了。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="折线图样式设置"><a href="#%E6%8A%98%E7%BA%BF%E5%9B%BE%E6%A0%B7%E5%BC%8F%E8%AE%BE%E7%BD%AE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>折线图样式设置</h2>

+<p>折线图中折线的样式可以通过 <code>lineStyle</code> 设置。可以为其指定颜色、线宽、折线类型、阴影、不透明度等等，具体的可以参考配置项手册 <a href="https://echarts.apache.org/option.html#series-line.lineStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.lineStyle</code></a> 了解。这里，我们以设置颜色（color）、线宽（width）和折线类型（type）为例说明。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>这里设置折线宽度时，数据点描边的宽度是不会跟着改变的，而应该在数据点的配置项中另外设置。</p>
+<h3 id="数据点的样式"><a href="#%E6%95%B0%E6%8D%AE%E7%82%B9%E7%9A%84%E6%A0%B7%E5%BC%8F" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据点的样式</h3>
+<p>数据点的样式可以通过 <a href="https://echarts.apache.org/option.html#series-line.itemStyle" rel="nofollow noopener noreferrer" target="_blank"><code>series.itemStyle</code></a> 指定填充颜色（color）、描边颜色（borderColor）、描边宽度（borderWidth）、描边类型（borderType）、阴影（shadowColor）、不透明度（opacity）等。与折线样式的设置十分相似，这里不再展开说明。</p>
+<h2 id="在数据点处显示数值"><a href="#%E5%9C%A8%E6%95%B0%E6%8D%AE%E7%82%B9%E5%A4%84%E6%98%BE%E7%A4%BA%E6%95%B0%E5%80%BC" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>在数据点处显示数值</h2>
+<p>在系列中，这数据点的标签通过 <a href="https://echarts.apache.org/option.html#series-line.label" rel="nofollow noopener noreferrer" target="_blank"><code>series.label</code></a> 属性指定。如果将 <code>label</code> 下的 <code>show</code> 指定为<code>true</code>，则表示该数值默认时就显示；如果为 <code>false</code>，而 <a href="https://echarts.apache.org/option.html#series-line.emphasis.label.show" rel="nofollow noopener noreferrer" target="_blank"><code>series.emphasis.label.show</code></a> 为 <code>true</code>，则表示只有在鼠标移动到该数据时，才显示数值。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="空数据"><a href="#%E7%A9%BA%E6%95%B0%E6%8D%AE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>空数据</h2>
+<p>在一个系列中，可能一个横坐标对应的取值是“空”的，将其设为 0 有时并不能满足我们的期望--空数据不应被其左右的数据连接。</p>
+<p>在 ECharts 中，我们使用字符串 <code>'-'</code> 表示空数据，这对其他系列的数据也是适用的。</p>

+<p>饼图主要用于表现不同类目的数据在总和中的占比。每个的弧度表示数据数量的比例。</p>

+<p>饼图的配置和折线图、柱状图略有不同，不再需要配置坐标轴，而是把数据名称和值都写在系列中。以下是一个最简单的饼图的例子。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>需要注意的是，这里是 <code>value</code> 不需要是百分比数据，ECharts 会根据所有数据的 <code>value</code> ，按比例分配它们在饼图中对应的弧度。</p>

+<p>饼图的半径可以通过 <a href="https://echarts.apache.org/option.html#series-pie.radius" rel="nofollow noopener noreferrer" target="_blank"><code>series.radius</code></a> 设置，可以是诸如 <code>'60%'</code> 这样相对的百分比字符串，或是 <code>200</code> 这样的绝对像素数值。当它是百分比字符串时，它是相对于容器宽高中较小的一条边的。也就是说，如果宽度大于高度，则百分比是相对于高度的，反之则反；当它是数值型时，它表示绝对的像素大小。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="如果数据和为-0，不显示饼图"><a href="#%E5%A6%82%E6%9E%9C%E6%95%B0%E6%8D%AE%E5%92%8C%E4%B8%BA-0%EF%BC%8C%E4%B8%8D%E6%98%BE%E7%A4%BA%E9%A5%BC%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>如果数据和为 0，不显示饼图</h2>
+<p>在默认情况下，如果数据值和为 0，会显示平均分割的扇形。比如，如果有 4 个数据项，并且每个数据项都是 0，则每个扇形都是 90°。如果我们希望在这种情况下不显示任何扇形，可以将 <a href="https://echarts.apache.org/option.html#series-pie.stillShowZeroSum" rel="nofollow noopener noreferrer" target="_blank"><code>series.stillShowZeroSum</code></a> 设为 <code>false</code>。</p>

+<p>圆环图同样可以用来表示数据占总体的比例，相比于饼图，它中间空余的部分可以用来显示一些额外的文字等信息，因而也是一种常用的图表类型。</p>
+<h2 id="基础圆环图"><a aria-hidden="true" href="#%E5%9F%BA%E7%A1%80%E5%9C%86%E7%8E%AF%E5%9B%BE" tabindex="-1"><span class="icon icon-link"></span></a>基础圆环图</h2>
+<p>在 ECharts 中，饼图的半径除了上一小节提到的，可以是一个数值或者字符串之外，还可以是一个包含两个元素的数组，每个元素可以为数值或字符串。当它是一个数组时，它的前一项表示内半径，后一项表示外半径，这样就形成了一个圆环图。</p>
+<p>从这个角度上来说，可以认为饼图是一个内半径为 0 的圆环图，也就是说，饼图是圆环图的特例。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>如果半径是数组，其中的两项也可以一项是数值，另一项是百分比形式的字符串。但是这样可能导致在某些分辨率下，内半径小于外半径。ECharts 会自动使用小的一项作为内半径，但是仍应小心这样可能会导致的非预期效果。</p>
+<h2 id="在圆环图中间显示高亮扇形对应的文字"><a aria-hidden="true" href="#%E5%9C%A8%E5%9C%86%E7%8E%AF%E5%9B%BE%E4%B8%AD%E9%97%B4%E6%98%BE%E7%A4%BA%E9%AB%98%E4%BA%AE%E6%89%87%E5%BD%A2%E5%AF%B9%E5%BA%94%E7%9A%84%E6%96%87%E5%AD%97" tabindex="-1"><span class="icon icon-link"></span></a>在圆环图中间显示高亮扇形对应的文字</h2>
+<p>上面的例子展现了在圆环图中间显示固定文字的例子，下面我们要介绍，如何在圆环图中间显示鼠标高亮的扇形对应的文字。实现这一效果的思路是，利用系列的 <code>label</code>（默认用扇形颜色显示数据的 <code>name</code>），显示在圆环图中间。在默认情况下不显示系列的 <code>label</code>，在高亮时显示。具体的代码如下：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>其中，<code>avoidLabelOverlap</code> 是用来控制是否由 ECharts 调整标签位置以实现防止标签重叠。它的默认值是 <code>true</code>，而在这里，我们不希望标签位置调整到不是中间的位置，因此我们需要将其设为 <code>false</code>。</p>
+<p>这样，圆环图中间会显示高亮数据的 <code>name</code> 值。</p></div> <div class="table-of-contents"><h4 class="toc-container-header">本页目录</h4> <ul><li class="toc2"><a href="/echarts-handbook/zh/application/chart-types/pie/doughnut#%E5%9F%BA%E7%A1%80%E5%9C%86%E7%8E%AF%E5%9B%BE">基础圆环图</a></li><li class="toc2"><a href="/echarts-handbook/zh/application/chart-types/pie/doughnut#%E5%9C%A8%E5%9C%86%E7%8E%AF%E5%9B%BE%E4%B8%AD%E9%97%B4%E6%98%BE%E7%A4%BA%E9%AB%98%E4%BA%AE%E6%89%87%E5%BD%A2%E5%AF%B9%E5%BA%94%E7%9A%8 [...]

+<p>散点图，也是一种常见的图表类型。散点图由许多“点”组成，有时，这些点用来表示数据在坐标系中的位置（比如在笛卡尔坐标系下，表示数据在 x 轴和 y 轴上的坐标；在地图坐标系下，表示数据在地图上的某个位置等）；有时，这些点的大小、颜色等属性也可以映射到数据值，用以表现高维数据。</p>
+<h2 id="最简单的散点图"><a href="#%E6%9C%80%E7%AE%80%E5%8D%95%E7%9A%84%E6%95%A3%E7%82%B9%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>最简单的散点图</h2>
+<p>下面是一个横坐标为类目轴、纵坐标为数值轴的最简单的散点图配置：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="笛卡尔坐标系下的散点图"><a href="#%E7%AC%9B%E5%8D%A1%E5%B0%94%E5%9D%90%E6%A0%87%E7%B3%BB%E4%B8%8B%E7%9A%84%E6%95%A3%E7%82%B9%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>笛卡尔坐标系下的散点图</h2>
+<p>在上文的例子中，散点图的横坐标都是离散的类目轴，而纵坐标都是连续的数值轴。而对于散点图而言，另一种常见的场景是，两个坐标轴均为连续的数值轴，也就是笛卡尔坐标系。这时的系列形式略有不同，数据的横坐标和纵坐标一同写在 <code>data</code> 中，而非坐标轴中。</p>

+<h2 id="散点图样式设置"><a href="#%E6%95%A3%E7%82%B9%E5%9B%BE%E6%A0%B7%E5%BC%8F%E8%AE%BE%E7%BD%AE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>散点图样式设置</h2>

+<p>图形（symbol）指的是散点图中数据“点”的形状。有三类图形可选，一种是 ECharts 内置形状，第二种是图片，第三种是 SVG 的路径。</p>
+<p>ECharts 内置形状包括：圆形、矩形、圆角矩形、三角形、菱形、大头针形、箭头形，分别对应<code>'circle'</code>、<code>'rect'</code>、<code>'roundRect'</code>、<code>'triangle'</code>、<code>'diamond'</code>、<code>'pin'</code>、<code>'arrow'</code>。使用内置形状时，只要将 <code>symbol</code> 属性指定为形状名称对应的字符串即可。</p>
+<p>如果想要将图形指定为任意的图片，以 <code>'image://'</code> 开头，后面跟图片的绝对或相对地址。形如：<code>'image://http://example.com/xxx.png'</code> 或 <code>'image://./xxx.png'</code>。</p>
+<p>除此之外，还支持 SVG 的路径作为矢量图形，将 <code>symbol</code> 设置为以 <code>'path://'</code> 开头的 SVG 路径即可。使用矢量图形的好处是，图片不会因为缩放而产生锯齿或模糊，并且通常而言比图片形式的文件大小更小。路径的查看方法为，打开一个 <code>SVG</code> 文件，找到形如 <code><path d="M… L…"></path></code> 的路径，将 <code>d</code> 的值添加在 <code>'path://'</code> 后即可。</p>
+<p>下面，我们展示一个将图形设置为矢量爱心形状的方式。</p>
+<p>首先，我们需要一个爱心的 SVG 文件，可以使用矢量编辑软件绘制，或者从网上下载到相关资源。其内容如下：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-xml line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" [...]
+<p>在 ECharts 的 <code>symbol</code> 配置项中，我们使用 <code>d</code> 的值作为路径。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>这样，就能得到爱心形状的图形作为点的形状了。</p>
+<h3 id="图形的大小"><a href="#%E5%9B%BE%E5%BD%A2%E7%9A%84%E5%A4%A7%E5%B0%8F" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>图形的大小</h3>
+<p>图形大小可以使用 <a href="https://echarts.apache.org/option.html#series-scatter.symbolSize" rel="nofollow noopener noreferrer" target="_blank"><code>series.symbolSize</code></a> 控制。它既可以是一个表示图形大小的像素值，也可以是一个包含两个 number 元素的数组，分别表示图形的宽和高。</p>
+<p>除此之外，它还可以是一个回调函数，其参数格式为：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-ts line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>第一个参数为数据值，第二个参数是数据项的其他参数。</p>
+<p>在下面的例子中，我们将散点图点的大小设置为与其数据值成正比。</p>

+<p>百度智能小程序上的 ECharts 以动态库的形式开放，因此开发者的使用方式与<a href="./zh/application/cross-platform/wechat-app">在微信小程序中使用 ECharts</a> 不太相同。尤其需要注意的是，前者需要在指定动态库名称的时候确定 ECharts 的版本号，而不能自行更换或使用自定义构建。这一点是由底层框架的技术实现决定的。具体来说，在指定百度智能小程序动态库名称的时候，需要通过 <code>provider</code> 指定动态库名称，具体参见<a href="http://smartprogram.baidu.com/docs/develop/framework/echarts/" rel="nofollow noopener noreferrer" target="_blank">文档</a>的「在项目中引用动态库」章节。</p>

+<p><a href="zh/get-started">入门示例</a>中的数据是在初始化后<code>setOption</code>中直接填入的，但是很多时候可能数据需要异步加载后再填入。<code>ECharts</code> 中实现异步数据的更新非常简单，在图表初始化后不管任何时候只要通过 jQuery 等工具异步获取数据后通过 <code>setOption</code> 填入数据和配置项就行。</p>

+<iframe width="100%" height="350" src="https://echarts.apache.org/examples/zh/view.html?c=doc-example/tutorial-async"></iframe>
+<p>ECharts 中在更新数据的时候需要通过<code>name</code>属性对应到相应的系列，上面示例中如果<code>name</code>不存在也可以根据系列的顺序正常更新，但是更多时候推荐更新数据的时候加上系列的<code>name</code>数据。</p>
+<h2 id="loading-动画"><a href="#loading-%E5%8A%A8%E7%94%BB" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>loading 动画</h2>
+<p>如果数据加载时间较长，一个空的坐标轴放在画布上也会让用户觉得是不是产生 bug 了，因此需要一个 loading 的动画来提示用户数据正在加载。</p>
+<p>ECharts 默认有提供了一个简单的加载动画。只需要调用 <a href="api.html#echartsInstance.showLoading">showLoading</a> 方法显示。数据加载完成后再调用 <a href="api.html#echartsInstance.hideLoading">hideLoading</a> 方法隐藏加载动画。</p>

+<p>ECharts 由数据驱动，数据的改变驱动图表展现的改变，因此动态数据的实现也变得异常简单。</p>
+<p>所有数据的更新都通过 <a href="~api.html#echartsInstance.setOption">setOption</a>实现，你只需要定时获取数据，<a href="~api.html#echartsInstance.setOption">setOption</a> 填入数据，而不用考虑数据到底产生了那些变化，ECharts 会找到两组数据之间的差异然后通过合适的动画去表现数据的变化。</p>

+<p>本篇通过介绍一个实现拖拽的小例子来介绍如何在 Apache ECharts<sup>TM</sup> 中实现复杂的交互。</p>
+<iframe width="100%" height="400" src="https://echarts.apache.org/examples/zh/view.html?c=line-draggable"></iframe>
+<p>这个例子主要做到了这样一件事，用鼠标可以拖拽曲线的点，从而改变曲线的形状。例子很简单，但是有了这个基础我们还可以做更多的事情，比如在图中进行可视化得编辑。所以我们从这个简单的例子开始。</p>
+<p>echarts 本身没有提供封装好的“拖拽改变图表”这样比较业务定制的功能。但是这个功能开发者可以通过 API 扩展实现。</p>
+<h2 id="实现基本的拖拽功能"><a href="#%E5%AE%9E%E7%8E%B0%E5%9F%BA%E6%9C%AC%E7%9A%84%E6%8B%96%E6%8B%BD%E5%8A%9F%E8%83%BD" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>实现基本的拖拽功能</h2>
+<p>在这个例子中，基础的图表是一个 <a href="https://echarts.apache.org/option.html#series-line" rel="nofollow noopener noreferrer" target="_blank">折线图 (series-line)</a>。参见如下配置：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>既然折线中原生的点没有拖拽功能，我们就为它加上拖拽功能：用 <a href="https://echarts.apache.org/option.html#graphic" rel="nofollow noopener noreferrer" target="_blank">graphic</a> 组件，在每个点上面，覆盖一个隐藏的可拖拽的圆点。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>上面的代码中，使用 <a href="api.html#echartsInstance.convertToPixel">convertToPixel</a> 这个 API，进行了从 data 到“像素坐标”的转换，从而得到了每个圆点应该在的位置，从而能绘制这些圆点。<code>myChart.convertToPixel('grid', dataItem)</code> 这句话中，第一个参数 <code>'grid'</code> 表示 <code>dataItem</code> 在 <a href="https://echarts.apache.org/option.html#grid" rel="nofollow noopener noreferrer" target="_blank">grid</a> 这个组件中（即直角坐标系）中进行转换。所谓“像素坐标”，就是以 echarts 容器 dom element 的左上角为零点的以像素为单位的坐标系中的坐标。</p>
+<p>注意这件事需要在第一次 setOption 后再进行，也就是说，须在坐标系（<a href="https://echarts.apache.org/option.html#grid" rel="nofollow noopener noreferrer" target="_blank">grid</a>）初始化后才能调用 <code>myChart.convertToPixel('grid', dataItem)</code>。</p>
+<p>有了这段代码后，就有了诸个能拖拽的点。接下来要为每个点，加上拖拽响应的事件：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>上面的代码中，使用了 <a href="https://echarts.apache.org//api.html#echartsInstance.convertFromPixel" rel="nofollow noopener noreferrer" target="_blank">convertFromPixel</a> 这个 API。它是 <a href="https://echarts.apache.org//api.html#echartsInstance.convertToPixel" rel="nofollow noopener noreferrer" target="_blank">convertToPixel</a> 的逆向过程。<code>myChart.convertFromPixel('grid', this.position)</code> 表示把当前像素坐标转换成 <a href="https://echarts.apache.org/option.html#grid" rel="nofollow noopener noreferrer" [...]
+<p>最后，为了使 dom 尺寸改变时，图中的元素能自适应得变化，加上这些代码：</p>

+<p>到此，拖拽的基本功能就完成了。但是想要更进一步得实时看到拖拽过程中，被拖拽的点的 data 值的变化状况，我们可以使用 <a href="https://echarts.apache.org/option.html#tooltip" rel="nofollow noopener noreferrer" target="_blank">tooltip</a> 组件来实时显示这个值。但是，tooltip 有其默认的“显示”“隐藏”触发规则，在我们拖拽的场景中并不适用，所以我们还要手动定制 tooltip 的“显示”“隐藏”行为。</p>
+<p>在上述代码中分别添加如下定义：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]

+<p>Apache ECharts<sup>TM</sup> 中的文本标签从 v3.7 开始支持富文本模式，能够：</p>
+<ul>
+<li>定制文本块整体的样式（如背景、边框、阴影等）、位置、旋转等。</li>
+<li>对文本块中个别片段定义样式（如颜色、字体、高宽、背景、阴影等）、对齐方式等。</li>
+<li>在文本中使用图片做小图标或者背景。</li>
+<li>特定组合以上的规则，可以做出简单表格、分割线等效果。</li>
+</ul>
+<p>开始下面的介绍之前，先说明一下下面会使用的两个名词的含义：</p>
+<ul>
+<li>文本块（Text Block）：文本标签块整体。</li>
+<li>文本片段（Text fragment）：文本标签块中的部分文本。</li>
+</ul>
+<p>如下图示例：</p>
+<iframe width="400" height="300" src="https://echarts.apache.org/examples/zh/view.html?c=doc-example/text-block-fragment"></iframe>
+<h2 id="文本样式相关的配置项"><a href="#%E6%96%87%E6%9C%AC%E6%A0%B7%E5%BC%8F%E7%9B%B8%E5%85%B3%E7%9A%84%E9%85%8D%E7%BD%AE%E9%A1%B9" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>文本样式相关的配置项</h2>
+<p>echarts 提供了丰富的文本标签配置项，包括：</p>
+<ul>
+<li>字体基本样式设置：<code>fontStyle</code>、<code>fontWeight</code>、<code>fontSize</code>、<code>fontFamily</code>。</li>
+<li>文字颜色：<code>color</code>。</li>
+<li>文字描边：<code>textBorderColor</code>、<code>textBorderWidth</code>。</li>
+<li>文字阴影：<code>textShadowColor</code>、<code>textShadowBlur</code>、<code>textShadowOffsetX</code>、<code>textShadowOffsetY</code>。</li>
+<li>文本块或文本片段大小：<code>lineHeight</code>、<code>width</code>、<code>height</code>、<code>padding</code>。</li>
+<li>文本块或文本片段的对齐：<code>align</code>、<code>verticalAlign</code>。</li>
+<li>文本块或文本片段的边框、背景（颜色或图片）：<code>backgroundColor</code>、<code>borderColor</code>、<code>borderWidth</code>、<code>borderRadius</code>。</li>
+<li>文本块或文本片段的阴影：<code>shadowColor</code>、<code>shadowBlur</code>、<code>shadowOffsetX</code>、<code>shadowOffsetY</code>。</li>
+<li>文本块的位置和旋转：<code>position</code>、<code>distance</code>、<code>rotate</code>。</li>
+</ul>
+<p>可以在各处的 <code>rich</code> 属性中定义文本片段样式。例如 <a href="option.html#series-bar.label.rich">series-bar.label.rich</a></p>
+<p>例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<blockquote>
+<p>注意：如果不定义 <code>rich</code>，不能指定文字块的 <code>width</code> 和 <code>height</code>。</p>
+</blockquote>
+<h2 id="文本、文本框、文本片段的基本样式和装饰"><a href="#%E6%96%87%E6%9C%AC%E3%80%81%E6%96%87%E6%9C%AC%E6%A1%86%E3%80%81%E6%96%87%E6%9C%AC%E7%89%87%E6%AE%B5%E7%9A%84%E5%9F%BA%E6%9C%AC%E6%A0%B7%E5%BC%8F%E5%92%8C%E8%A3%85%E9%A5%B0" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>文本、文本框、文本片段的基本样式和装饰</h2>
+<p>每个文本可以设置基本的字体样式：<code>fontStyle</code>、<code>fontWeight</code>、<code>fontSize</code>、<code>fontFamily</code>。</p>
+<p>可以设置文字的颜色 <code>color</code> 和边框的颜色 <code>textBorderColor</code>、<code>textBorderWidth</code>。</p>
+<p>文本框可以设置边框和背景的样式：<code>borderColor</code>、<code>borderWidth</code>、<code>backgroundColor</code>、<code>padding</code>。</p>
+<p>文本片段也可以设置边框和背景的样式：<code>borderColor</code>、<code>borderWidth</code>、<code>backgroundColor</code>、<code>padding</code>。</p>
+<p>例如：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="标签的位置"><a href="#%E6%A0%87%E7%AD%BE%E7%9A%84%E4%BD%8D%E7%BD%AE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>标签的位置</h2>
+<p>对于折线图、柱状图、散点图等，均可以使用 <code>label</code> 来设置标签。标签的相对于图形元素的位置，一般使用 <a href="option.html#series-scatter.label.position">label.position</a>、<a href="option.html#series-scatter.label.distance">label.distance</a> 来配置。</p>
+<p>试试在下面例子中修改<code>position</code>和<code>distance</code> 属性：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<blockquote>
+<p>注意：<code>position</code> 在不同的图中可取值有所不同。<code>distance</code> 并不是在每个图中都支持。详情请参见 <a href="https://echarts.apache.org/option.html" rel="nofollow noopener noreferrer" target="_blank">option 文档</a>。</p>
+</blockquote>
+<h2 id="标签的旋转"><a href="#%E6%A0%87%E7%AD%BE%E7%9A%84%E6%97%8B%E8%BD%AC" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>标签的旋转</h2>
+<p>某些图中，为了能有足够长的空间来显示标签，需要对标签进行旋转。例如：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>这种场景下，可以结合 <a href="option.html#series-bar.label.align">align</a> 和 <a href="option.html#series-bar.label.verticalAlign">verticalAlign</a> 来调整标签位置。</p>
+<p>注意，逻辑是，先使用 <code>align</code> 和 <code>verticalAlign</code> 定位，再旋转。</p>
+<h2 id="文本片段的排版和对齐"><a href="#%E6%96%87%E6%9C%AC%E7%89%87%E6%AE%B5%E7%9A%84%E6%8E%92%E7%89%88%E5%92%8C%E5%AF%B9%E9%BD%90" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>文本片段的排版和对齐</h2>
+<p>关于排版方式，每个文本片段，可以想象成 CSS 中的 <code>inline-block</code>，在文档流中按行放置。</p>
+<p>每个文本片段的内容盒尺寸（<code>content box size</code>），默认是根据文字大小决定的。但是，也可以设置 <code>width</code>、<code>height</code> 来强制指定，虽然一般不会这么做（参见下文）。文本片段的边框盒尺寸（<code>border box size</code>），由上述本身尺寸，加上文本片段的 <code>padding</code> 来得到。</p>
+<p>只有 <code>'\n'</code> 是换行符，能导致换行。</p>
+<p>一行内，会有多个文本片段。每行的实际高度，由 <code>lineHeight</code> 最大的文本片段决定。文本片段的 <code>lineHeight</code> 可直接在 <code>rich</code> 中指定，也可以在 <code>rich</code> 的父层级中统一指定而采用到 <code>rich</code> 的所有项中，如果都不指定，则取文本片段的边框盒尺寸（<code>border box size</code>）。</p>
+<p>在一行的 <code>lineHeight</code> 被决定后，一行内，文本片段的竖直位置，由文本片段的 <code>verticalAlign</code> 来指定（这里和 CSS 中的规则稍有不同）：</p>
+<ul>
+<li><code>'bottom'</code>：文本片段的盒的底边贴住行底。</li>
+<li><code>'top'</code>：文本片段的盒的顶边贴住行顶。</li>
+<li><code>'middle'</code>：居行中。</li>
+</ul>
+<p>文本块的宽度，可以直接由文本块的 <code>width</code> 指定，否则，由最长的行决定。宽度决定后，在一行中进行文本片段的放置。文本片段的 <code>align</code> 决定了文本片段在行中的水平位置：</p>
+<ul>
+<li>首先，从左向右连续紧靠放置 <code>align</code> 为 <code>'left'</code> 的文本片段盒。</li>
+<li>然后，从右向左连续紧靠放置 <code>align</code> 为 <code>'right'</code> 的文本片段盒。</li>
+<li>最后，剩余的没处理的文本片段盒，紧贴着，在中间剩余的区域中居中放置。</li>
+</ul>
+<p>关于文字在文本片段盒中的位置：</p>
+<ul>
+<li>如果 <code>align</code> 为 <code>'center'</code>，则文字在文本片段盒中是居中的。</li>
+<li>如果 <code>align</code> 为 <code>'left'</code>，则文字在文本片段盒中是居左的。</li>
+<li>如果 <code>align</code> 为 <code>'right'</code>，则文字在文本片段盒中是居右的。</li>
+</ul>
+<h2 id="特殊效果：图标、分割线、标题块、简单表格"><a href="#%E7%89%B9%E6%AE%8A%E6%95%88%E6%9E%9C%EF%BC%9A%E5%9B%BE%E6%A0%87%E3%80%81%E5%88%86%E5%89%B2%E7%BA%BF%E3%80%81%E6%A0%87%E9%A2%98%E5%9D%97%E3%80%81%E7%AE%80%E5%8D%95%E8%A1%A8%E6%A0%BC" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>特殊效果：图标、分割线、标题块、简单表格</h2>
+<p>看下面的例子：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>文本片段的 <code>backgroundColor</code> 可以指定为图片后，就可以在文本中使用图标了：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>分割线实际是用 border 实现的：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>标题块是使用 <code>backgroundColor</code> 实现的：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>简单表格的设定，其实就是给不同行上纵向对应的文本片段设定同样的宽度就可以了。见 <a href="https://echarts.apache.org/examples/zh/editor.html?c=pie-rich-text" rel="nofollow noopener noreferrer" target="_blank">该例子</a></p></div> <div class="table-of-contents"><h4 class="toc-container-header">本页目录</h4> <ul><li class="toc2"><a href="/echarts-handbook/zh/application/label/rich-text#%E6%96%87%E6%9C%AC%E6%A0%B7%E5%BC%8F%E7%9B%B8%E5%85%B3%E7%9A%84%E9%85%8D%E7%BD%AE%E9%A1%B9">文本样式相关的配置项</a></li><li class="toc2"><a href="/echarts-hand [...]

+<p>需要注意的是注意为了保证打包的体积是最小的，ECharts 按需引入的时候不再提供任何渲染器，所以需要选择引入<code>CanvasRenderer</code>或者<code>SVGRenderer</code>作为渲染器。这样的好处是假如你只需要使用 svg 渲染模式，打包的结果中就不会再包含无需使用的<code>CanvasRenderer</code>模块。</p>

+<p>在 Apache ECharts 中我们一直把自然流畅的过渡动画作为我们的一个重要特性，我们希望能够动画去关联数据的变化，让整个数据的变化不会突兀的反应在图形上。</p>
+<p>在之前的版本中，过渡动画主要应用在了相同类型的图形的位置，尺寸，形状上，而且只能作用在相同类型的系列上。比如下面例子就是通过饼图中扇区形状的变化反映了数据分布的变化：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h3 id="跨系列的变形动画"><a href="#%E8%B7%A8%E7%B3%BB%E5%88%97%E7%9A%84%E5%8F%98%E5%BD%A2%E5%8A%A8%E7%94%BB" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>跨系列的变形动画</h3>
+<p>这次从 5.2.0 开始，我们引入了更强大的全局过渡动画 Universal Transition，让过渡动画不再局限于相同类型的系列之间。</p>
+<p>在设置<code>universalTransition: true</code>开启全局过渡动画后，从饼图切换到柱状图，或者从柱状图切换成散点图，甚至旭日图和矩形树图这类复杂的图表之间，都可以通过形变的方式自然的通过动画过渡。</p>
+<p>饼图和柱状图之间的切换：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>更多的常见基础图表之间的过渡：</p>
+<p><img alt="" src="images/5-2-0/universal-transition.gif"></p>
+<p>这个动画过渡也不仅仅是局限在基础的折柱饼中，在柱状图和地图之间:</p>
+<p><img alt="" src="images/5-2-0/universal-transition-2.gif"></p>
+<p>或者旭日图和矩形树图之间，甚至非常灵活的自定义系列之间都可以进行动画的过渡</p>
+<p><img alt="" src="images/5-2-0/universal-transition-3.gif"></p>
+<blockquote>
+<p>注意需要配置系列的 id 来保证需要动画过渡的系列之间能够一一对应</p>
+</blockquote>
+<h3 id="数据的分裂和合并动画"><a href="#%E6%95%B0%E6%8D%AE%E7%9A%84%E5%88%86%E8%A3%82%E5%92%8C%E5%90%88%E5%B9%B6%E5%8A%A8%E7%94%BB" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据的分裂和合并动画</h3>
+<p>除了常见的数据更新，有时候我们还会碰到数据的聚合，下钻等交互后的更新，这个时候我们就不能直接应用一对一的动画过渡，而需要使用更多像分裂，合并这样的动画效果，来能够正确的通过图形的动画变换表达出数据的变换。</p>
+<p>为了能够表达数据之间多对多的联系，在 5.2.0 中我们新引入了一个数据组<code>groupId</code>的概念，我们可以通过 <a href="https://echarts.apache.org/option.html#series-bar.dataGroupId" rel="nofollow noopener noreferrer" target="_blank">series.dataGroupId</a> 设置整个系列所属的组，或者更细粒度的通过 <a href="https://echarts.apache.org/option.html#series-bar.dataGroupId" rel="nofollow noopener noreferrer" target="_blank">series.data.groupId</a> 设置每个数据所属的组。如果你使用了<code>dataset</code>管理数据则更方便了，可以使用<code>encode.itemGroupId</code>来指定一个维度编码成<code>groupId</ [...]
+<p>比如我们要实现一个柱状图下钻的动画，可以将下钻后的整个系列的数据都设置同一个<code>groupId</code>，然后跟下钻前的数据对应起来：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>通过<code>groupId</code>，我们还可以实现更丰富的聚合，下钻动画。</p>
+<p>数据的聚合：</p>
+<p><img alt="" src="images/5-2-0/group-transition.gif"></p>
+<p>单系列下钻成两个系列：</p>

+<p>在上面全局过渡动画的示例中大家可能有注意到我们使用了一个之前版本没有的<code>colorBy</code>配置项，这个配置项也是我们这个版本新增加的一个特性，用来给系列配置不同粒度的调色盘取色。这个配置目前支持两种策略：</p>
+<ul>
+<li><code>'series'</code> 按照系列取色，同一系列中的所有数据都是用相同的颜色。</li>
+<li><code>'data'</code> 按照数据项取色，每个数据项都使用不同的颜色。</li>
+</ul>
+<p>在之前我们是按照系列的类型固定了这个策略，比如柱状图就是固定<code>'series'</code>的策略，而饼图则是固定<code>'data'</code>的策略。</p>
+<p>而现在新增这个配置项后，我们可以在柱状图中给每个数据项都分配不同的颜色：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>或者在饼图中统一使用一个颜色：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>从而避免了减少我们去找调色盘颜色然去一一设置的麻烦。后续我们会对这个配置项做进一步的增强，提供更多粒度的调色盘取色的配置。</p>

+<p>这个版本中我们给极坐标上的柱状图添加了标签的显示，并且支持丰富的标签定位配置。下面是一个最常见的标签显示在端点的进度图：</p>

+<p>在之前，如果饼图没有数据，画面中可能就是完全空白的，因为没有任何的反馈，所以用户会疑惑是不是出 bug 了导致图中没有内容。</p>
+<p>为了解决这个问题，这个版本我们会默认在无可显示数据的时候显示一个灰色的占位圆以防止画面中完全空白。我们可以通过<code>emptyCircleStyle</code>配置这个占位圆的样式。</p>
+<div class="nuxt-content-highlight"><!----></div>

+<p>我们从 4.0 开始引入了 <a href="https://echarts.apache.org/option.html#dataset" rel="nofollow noopener noreferrer" target="_blank">dataset</a> 用来管理图表的数据，通常情况下<code>dataset</code>提供了更方便的数据管理方式而且跟传统的方式不会有什么性能上的差别。但是在一些极端的特别高维（>100）数据的场景下，我们还是会碰到一些性能急剧下降的问题，比如下面这种通过一千个系列去可视化千维数据的场景（来自 <a href="https://github.com/apache/echarts/issues/11907" rel="nofollow noopener noreferrer" target="_blank">#11907</a>），甚至可能导致假死。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>产生这个性能问题的原因是因为我们在底层会在每个系列都按照系列的需要处理一遍这个超高维度的 dataset 并且保存一份处理过后的数据以及数据的维度等元信息。这意味着刚才那个例子中需要处理并保存<code>1000 x 1000</code>个维度的信息，带来了巨大的内存和 GC 的压力，从而导致了高维度的性能的急剧下降。</p>
+<p>在新版本中我们对这个问题做了优化，所有系列都尽可能共享 dataset 的数据（能否共享取决于系列怎么使用这份数据）存储而非每个系列都处理并存储一次，并且只处理和存储了使用到的维度。这些优化保证了内存不会随着 dataset 维度和系列的增长而爆炸，大幅度的提升了这个极端场景下的初始化性能。刚才例子的渲染耗时也从假死降低到了可接受的<code>300ms</code>以下。</p>
+<p>这次优化带来收益的还不只是这种高维的场景，在使用维度不高但是数据量很大的 dataset 的时候，因为数据的共享所以多个系列只处理了一遍数据，因此也可以带来显著的性能提升。</p>
+<h2 id="自定义系列的类型优化"><a href="#%E8%87%AA%E5%AE%9A%E4%B9%89%E7%B3%BB%E5%88%97%E7%9A%84%E7%B1%BB%E5%9E%8B%E4%BC%98%E5%8C%96" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>自定义系列的类型优化</h2>
+<p>自定义系列提供了非常灵活的创建系列图形的方式，相对于其它系列，自定义系列的上手成本会更高，而且容易出错，因此在这个版本中，我们进一步的优化了自定义系列中的核心方法<code>renderItem</code>的类型，对于<code>renderItem</code>的参数和返回值类型做了更精确的推断，从而可以根据返回的图形类型推断出可以设置该图形的哪些属性：</p>

+<p>数据可视化在过去的几年中得到了长足的发展。开发者对于可视化产品的期待不再是简单的图表创建工具，而在交互、性能、数据处理等方面有了更高级的需求。</p>
+<p>Apache ECharts 始终致力于让开发者以更方便的方式创造灵活丰富的可视化作品。在最新推出的 Apache ECharts 5，我们着力加强了图表的叙事能力，让开发者可以以更简单的方式，讲述数据背后的故事。</p>
+<img src="images/feature-v5/echarts-5.png" width="800px">
+<p>“表·达”是 Apache ECharts 5 的核心，通过五大模块、十五项特性的全面升级，围绕可视化作品的叙事表达能力，让图“表”更能传“达”数据背后的故事，帮助开发者更轻松地创造满足各种场景需求的可视化作品。</p>
+<h2 id="动态叙事"><a href="#%E5%8A%A8%E6%80%81%E5%8F%99%E4%BA%8B" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>动态叙事</h2>
+<p>动画对于人类认知的重要性不言而喻。在之前的作品中，我们会通过初始化动画和过渡动画帮助用户理解数据变换之间的联系，让图表的出现和变换显得不那么生硬。这次，我们更是大幅度增强了我们的动画叙事能力，。希望能够进一步发挥动画对于用户认知的帮助作用，借助图表的动态叙事功能，帮助用户更容易理解图表背后表达的故事。</p>
+<h4 id="动态排序图"><a href="#%E5%8A%A8%E6%80%81%E6%8E%92%E5%BA%8F%E5%9B%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>动态排序图</h4>
+<p>Apache ECharts 5 新增支持动态排序柱状图（bar-racing）以及动态排序折线图（line-racing），帮助开发者方便地创建带有时序性的图表，展现数据随着时间维度上的变化，讲述数据的演变过程。</p>
+<iframe width="700" height="400" src="https://echarts.apache.org/examples/zh/view.html?c=bar-race-country"></iframe>
+
+
+<iframe width="700" height="400" src="https://echarts.apache.org/examples/zh/view.html?c=line-race"></iframe>
+<p>动态排序图展现了不同的类目随着时间在排名上的衍变。而开发者只需要通过几行简单的配置项就可以在 ECharts 中开启这样的效果。</p>
+<h4 id="自定义系列动画"><a href="#%E8%87%AA%E5%AE%9A%E4%B9%89%E7%B3%BB%E5%88%97%E5%8A%A8%E7%94%BB" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>自定义系列动画</h4>
+<p>除了动态排序图，Apache ECharts 5 在自定义系列中提供了更加丰富强大的动画效果，支持标签数值文本的插值动画，图形的形变（morph）、分裂（separate）、合并（combine）等效果的过渡动画。</p>
+<p>想象一下，用这些动态效果，你可以创造出多么令人称奇的可视化作品！</p>
+<h2 id="视觉设计"><a href="#%E8%A7%86%E8%A7%89%E8%AE%BE%E8%AE%A1" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>视觉设计</h2>
+<p>视觉设计的作用并不仅仅是为了让图表更好看，更重要的是，符合可视化原理的设计可以帮用户更快速地理解图表想表达的内容，并且尽可能消除不良设计带来的误解。</p>
+<h4 id="默认设计"><a href="#%E9%BB%98%E8%AE%A4%E8%AE%BE%E8%AE%A1" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>默认设计</h4>
+<p>我们发现，有很大一部分开发者使用了 ECharts 默认的主题样式，因而设计优雅、符合可视化原理的默认主题设计是非常重要的。在 Apache ECharts 5 中，我们重新设计了默认的主题样式，针对不同的系列和组件分别做了优化调整。以主题色为例，我们考量了颜色之间的区分度、与背景色的对比度、相邻颜色的和谐度等因素，并且确保色觉辨识障碍人士也能清楚地区分数据。</p>
+<img src="images/feature-v5/theme-color.png" width="400px">
+<p>我们以最常用的柱状图为例，来看看新版本浅色主题和深色主题的样式：</p>
+<img src="images/feature-v5/new-theme-light.png" width="500px">
+<img src="images/feature-v5/new-theme-dark.png" width="500px">
+<p>对于数据区域缩放，时间轴等交互组件，我们也设计了全新的样式并且提供了更好的交互体验：</p>
+<img src="images/feature-v5/dataZoom.png" width="500px">
+<img src="images/feature-v5/timeline.png" width="500px">
+<h4 id="标签"><a href="#%E6%A0%87%E7%AD%BE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>标签</h4>
+<p>标签是图表中的核心元素之一，清晰而明确的标签可以帮助用户对数据有更准确的理解。Apache ECharts 5 提供了多种新的标签功能，让密集的标签能清晰显示、准确表意。</p>
+<p>Apache ECharts 5 可以通过一个配置项开启自动隐藏重叠的标签。对于超出显示区域的标签，可以选择自动截断或者换行。密集的饼图标签，现在有了更美观的自动排布。</p>
+<p>这些功能可以帮助避免文字过于密集影响可读性。并且，无需开发者编写额外的代码就能默认生效，大大简化了开发者的开发成本。</p>
+<p>我们也提供了多个配置项来让开发者主动控制标签的布局策略，例如标签拖动、整体显示在画布边缘，用引导线和图形元素连接，并且仍可联动高亮表达关联关系。</p>
+<p>新的标签功能可以让你在移动端这样局限的空间内也可以有很优雅的标签展示：</p>
+<img src="images/feature-v5/pie-label.png" width="400px">
+<h4 id="时间轴"><a href="#%E6%97%B6%E9%97%B4%E8%BD%B4" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>时间轴</h4>
+<p>Apache ECharts 5 带来了适于表达时间标签刻度的时间轴。时间轴的默认设计更突出重要的信息，并且提供了更灵活的定制化能力，让开发者根据不同的需求定制时间轴的标签内容。</p>
+<p>首先，时间轴不再如之前般绝对平均分割，而是选取年、月、日、整点这类更有意义的点来展示，并且能同时显示不同层级的刻度。标签的 <code>formatter</code> 支持了时间模版（例如 <code>{yyyy}-{MM}-{dd}</code>），并且可以为不同时间粒度的标签指定不同的 <code>formatter</code>，结合已有的富文本标签，可以定制出醒目而多样的时间效果。</p>
+<p>不同的 dataZoom 粒度下时间刻度的显示：</p>
+<img src="images/feature-v5/time-axis.png" width="600px">
+<img src="images/feature-v5/time-axis-2.png" width="600px">
+<h4 id="提示框"><a href="#%E6%8F%90%E7%A4%BA%E6%A1%86" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>提示框</h4>
+<p>提示框（Tooltip）是一种最常用的可视化组件，可以帮助用户交互式地了解数据的详细信息。在 Apache ECharts 5 中，我们对提示框的样式进行了优化，通过对字体样式，颜色的调整，指向图形的箭头，跟随图形颜色的边框色等功能，让提示框的默认展示优雅又清晰。并且改进了富文本的渲染逻辑，确保显示效果与 HTML 方式一致，让用户在不同场景下可以选择不同的技术方案实现同样的效果。</p>
+<img src="images/feature-v5/new-tooltip.png" width="400px">
+<img src="images/feature-v5/new-tooltip-2.png" width="400px">
+<p>除此之外，我们这次也加上了提示框内的列表按照数值大小或者类目顺序排序的功能。</p>
+<h4 id="仪表盘"><a href="#%E4%BB%AA%E8%A1%A8%E7%9B%98" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>仪表盘</h4>
+<p>我们看到社区用户创建了很多酷炫的仪表盘图表，但是他们的配置方式往往比较复杂而取巧。因此，我们对仪表盘的功能作了全面升级，支持了图片或者矢量路径绘制指针、也支持了锚点（anchor）配置项、进度条（progress）、圆角效果等等配置项。</p>
+<p>不同样式的仪表盘指针：</p>
+<img src="images/feature-v5/gauge-pointer.png" width="600px">
+<p>这些升级，不仅可以让开发者用更简单的配置项实现酷炫的效果，而且带来了更丰富的定制能力。</p>
+<iframe width="600" height="600" src="https://echarts.apache.org/examples/zh/view.html?c=gauge-clock"></iframe>
+<h4 id="扇形圆角"><a href="#%E6%89%87%E5%BD%A2%E5%9C%86%E8%A7%92" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>扇形圆角</h4>
+<p>圆角可以带来更美观而柔和的视觉，也能够赋予更多的创造力。Apache ECharts 5 支持了饼图、旭日图、矩形树图的扇形圆角。可不要小看了简单的圆角配置项，合理地搭配其他的效果，就可以形成更具个性的的可视化作品。</p>
+<iframe width="400" height="400" src="https://echarts.apache.org/examples/zh/view.html?c=sunburst-borderRadius"></iframe>
+<h2 id="交互能力"><a href="#%E4%BA%A4%E4%BA%92%E8%83%BD%E5%8A%9B" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>交互能力</h2>
+<p>可视化作品的交互能力帮助用户探索了解作品，加深对于图表主旨的理解。</p>
+<h4 id="状态管理"><a href="#%E7%8A%B6%E6%80%81%E7%AE%A1%E7%90%86" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>状态管理</h4>
+<p>在 ECharts 4 中有高亮（emphasis）和普通（normal）两个交互的状态，在鼠标移到图形上的时候会进入高亮状态以区分该数据，开发者可以分别设置这两个状态的颜色，阴影等样式。</p>
+<p>这次在 Apache ECharts 5 中，我们在原先的鼠标 hover 高亮的基础上，新增加了<strong>淡出</strong>其它非相关元素的效果，从而可以达到聚焦目标数据的目的。</p>
+<p>比如在这个<a href="https://echarts.apache.org/examples/zh/editor.html?c=bar-y-category-stack" rel="nofollow noopener noreferrer" target="_blank">柱状图</a>的例子中，鼠标移到一个系列上的时候，其它非相关的系列就会淡出，从而可以更清晰的突出聚焦系列中数据的对比。在关系图，树图，旭日图，桑基等更复杂数据结构的图上，也可以通过淡出非相关元素来观察数据之间的联系。而且颜色，阴影等在高亮（emphasis）中可以设置的样式，现在也可以在淡出（blur）状态中设置了。</p>
+<p>除此之外，我们为所有系列还添加了<strong>点击选中</strong>这个之前只有在饼图、地图等少数系列中才能开启的交互，开发者可以设置为单选或多选模式，并且通过监听 <code>selectchanged</code> 事件获取到选中的所有图形然后进行更进一步的处理。与高亮和淡出一样，选中的样式也可以在 <code>select</code> 中配置。</p>
+<h4 id="性能提升"><a href="#%E6%80%A7%E8%83%BD%E6%8F%90%E5%8D%87" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>性能提升</h4>
+<h5 id="脏矩形渲染"><a href="#%E8%84%8F%E7%9F%A9%E5%BD%A2%E6%B8%B2%E6%9F%93" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>脏矩形渲染</h5>
+<p>Apache ECharts 5 新支持了脏矩形渲染，解决只有局部变化的场景下的性能瓶颈。在使用 Canvas 渲染器时，脏矩形渲染技术探测并只更新视图变化的部分，而不是任何变动都引起画布完全重绘。这能在一些特殊场景下帮助提高渲染帧率，例如在图形很多时候，鼠标频繁触发一些图形高亮的场景。以往这类场景，会使用额外的 Canvas 层以优化性能，但是这种方式不是所有场景都通用，而且对于复杂的样式的效果并不理想。脏矩形渲染很好地同时满足了性能和显示正确。</p>
+<p>脏矩形的可视化演示，红色框选部分为该帧重绘区域：</p>
+<img src="images/feature-v5/dirty-rect.gif" width="500px">
+<p>大家在新的示例页面选择开启脏矩形优化就可以看到该效果。</p>
+<h5 id="实时时序数据的折线图性能优化"><a href="#%E5%AE%9E%E6%97%B6%E6%97%B6%E5%BA%8F%E6%95%B0%E6%8D%AE%E7%9A%84%E6%8A%98%E7%BA%BF%E5%9B%BE%E6%80%A7%E8%83%BD%E4%BC%98%E5%8C%96" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>实时时序数据的折线图性能优化</h5>
+<p>除此之外，海量数据下折线图的性能也有了大幅度的性能提升。我们经常碰到大量的实时时序数据的高性能绘制的需求，这些数据可能需要几百或者几十毫秒更新一次。</p>
+<p>Apache ECharts 5 对这些场景下的 CPU 消耗、内存占用、初始化时间都进行了深度的优化，使得百万量级的数据也能做到实时的更新（每次更新耗时少于 30ms），甚至对于千万级的数据，也可以在 1s 内渲染完，并且保持很小的内存占用以及流畅的提示框（tooltip）等交互。</p>
+<h2 id="开发体验"><a href="#%E5%BC%80%E5%8F%91%E4%BD%93%E9%AA%8C" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>开发体验</h2>
+<p>我们希望如此强大的可视化工具可以被更多开发者以更简单的方式使用，因而开发者的开发体验也是我们非常关注的方面。</p>
+<h4 id="数据集"><a href="#%E6%95%B0%E6%8D%AE%E9%9B%86" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据集</h4>
+<p>ECharts 5 加强了数据集的数据转换能力，让开发者可以使用简单的方式实现常用的数据处理，如：数据过滤（filter）、排序（sort）、聚合（aggregate）、直方图（histogram）、简单聚类（clustering）、回归线计算（regression）等。开发者可以用统一的声明式方式来使用这些功能，可以方便地实现常用的数据操作。</p>
+<h4 id="国际化"><a href="#%E5%9B%BD%E9%99%85%E5%8C%96" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>国际化</h4>
+<p>ECharts 原有的国际化方案，采用的是根据不同的语言参数打包出不同的部署文件的形式。 这种方式，使动态的语言和静态的代码包绑定在一起，使用的时候只能通过重新加载不同语言版本的 ECharts 代码来达到切换语言的目的。</p>
+<p>因此，从 Apache ECharts 5 开始，动态的语言包和静态的代码包分离开。切换语言的时候，只需要加载相应语言包 ，通过类似挂载主题的方式，使用 <code>registerLocale</code> 函数挂载语言包对象 ，重新初始化后就完成了语言的切换 。</p>

+<h4 id="typescript-重构"><a href="#typescript-%E9%87%8D%E6%9E%84" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>TypeScript 重构</h4>
+<p>在近 8 年的时间里，Apache ECharts 已经发展成一个非常复杂的可视化库了，为了续可以更安全高效的进行重构和新功能的开发，我们在 Apache ECharts 5 的开发之初，使用 TypeScript 对代码进行了重写，TypeScript 所带来的强类型让我们更有信心地在 ECharts 5 开发的时候对代码进行大刀阔斧的重构以实现更多令人激动人心的特性。</p>
+<p>对于开发者，我们也可以从 TypeScript 代码直接生成更好更符合代码的<code>DTS</code>类型描述文件。在此之前，ECharts 的类型描述文件一直是由社区开发者帮我们维护并发布到<a href="https://github.com/DefinitelyTyped/DefinitelyTyped/tree/master/types/echarts" rel="nofollow noopener noreferrer" target="_blank">DefinityTyped</a>，这个有着不小的工作量，非常感谢大家的贡献。</p>
+<p>除此之外，如果开发者的组件是按需引入的，我们还提供了一个 <code>ComposeOption</code> 类型方法，可以组合出一个只包含了引入组件的配置项类型，可以带来更严格的类型检查，帮助你提前检测到未引入的组件类型。</p>
+<h2 id="可访问性"><a href="#%E5%8F%AF%E8%AE%BF%E9%97%AE%E6%80%A7" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>可访问性</h2>
+<p>Apache ECharts 一直非常重视无障碍设计，我们希望让视觉障碍人士也能平等了解图表传递的信息。并且也希望图表的开发者能以极低的开发成本实现这一点，因而有利于让开发者更愿意为视觉障碍人士提供支持。</p>
+<p>在上一个大版本中，我们支持了根据不同的图表类型和数据自动一键智能生成图表描述的功能，帮助开发者非常方便地支持图表的 DOM 描述信息。在 ECharts 5 中，我们也做了更多提高可访问性的设计，帮助视觉障碍人士更好地理解图表内容。</p>
+<h4 id="主题配色"><a href="#%E4%B8%BB%E9%A2%98%E9%85%8D%E8%89%B2" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>主题配色</h4>
+<p>我们在设计新版默认主题样式的时候，将无障碍设计作为一个重要的考量依据，对颜色的明度和色值都进行反复测试，帮助视觉辨识障碍用户清楚地识别图表数据。</p>
+<p>并且，针对有更进一步无障碍需求的开发者，我们还提供了特殊的高对比度主题，以更高对比度颜色的主题将数据作进一步区分。</p>
+<h4 id="贴花图案"><a href="#%E8%B4%B4%E8%8A%B1%E5%9B%BE%E6%A1%88" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>贴花图案</h4>
+<p>ECharts 5 还新增提供了贴花的功能，用图案辅助颜色表达，进一步帮助用户区分数据。</p>
+<iframe width="600" height="350" src="https://echarts.apache.org/examples/zh/view.html?c=doc-example/aria-decal-simple"></iframe>
+<p>此外，贴花图案还能在一些其他的场景下提供帮助，比如：在报纸、书籍之类只有单色或者非常少的颜色的印刷品中，帮助更好地区分数据；用图形元素方便用户对数据产生更直观的理解等。</p>
+<iframe width="600" height="350" src="https://echarts.apache.org/examples/zh/view.html?c=doc-example/aria-decal-newspaper"></iframe>
+<h2 id="小结"><a href="#%E5%B0%8F%E7%BB%93" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>小结</h2>
+<p>除了以上介绍的功能，Apache ECharts 还在非常多的细节中做了改进，帮助开发者更轻松地创建默认好用、配置灵活的图表，用图表讲述数据背后的故事。</p>
+<p>感谢所有使用过 ECharts，甚至参与过社区贡献的开发者，正是你们才使得 Apache ECharts 5 成为可能。我们会以更大的热情投入到未来的开发中，Apache ECharts 也会以更大的诚意和大家在 6 相见！</p></div> <div class="table-of-contents"><h4 class="toc-container-header">本页目录</h4> <ul><li class="toc2"><a href="/echarts-handbook/zh/basics/release-note/v5-feature#%E5%8A%A8%E6%80%81%E5%8F%99%E4%BA%8B">动态叙事</a></li><li class="toc2"><a href="/echarts-handbook/zh/basics/release-note/v5-feature#%E8%A7%86%E8%A7%89%E8%AE%BE%E8%AE%A1">视觉设计</a></li><li class="toc2"><a href="/ech [...]

+<p>本指南面向那些希望将 echarts 4.x（以下简称 <code>v4</code>）升级到 echarts 5.x（以下简称 <code>v5</code>）的用户。大家可以在 <a href="zh/basics/release-note/v5-feature">ECharts 5 新特性</a> 中了解这次<code>v5</code>带来了哪些值得升级的新特性。在绝大多数情况下，开发者用不着为这个升级做什么额外的事，因为 echarts 一直尽可能地保持 API 的稳定和向后兼容。但是，<code>v5</code> 仍然带来了一些非兼容改动，需要特别关注。此外，在一些情况下，<code>v5</code> 提供了更好的 API 用来取代之前的 API，这些被取代的 API 将不再被推荐使用（当然，我们尽量兼容了这些改动）。我们会在这篇文档里尽量详尽得解释这些改动。</p>

+<p>首先是默认主题的改动，<code>v5</code> 在配色等主题设计上做了很多的优化来达到更好的视觉效果。如果大家依旧想保留旧版本的颜色，可以手动声明颜色，如下：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>或者，做一个简单的 <code>v4</code> 主题：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]

+<p>如果使用者在 <code>v4</code> 中这样引用了 echarts：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>这两种方式，<code>v5</code> 中不再支持了。</p>
+<p>使用者需要如下更改代码解决这个问题：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h5 id="按需引入"><a href="#%E6%8C%89%E9%9C%80%E5%BC%95%E5%85%A5" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>按需引入</h5>
+<p>在 5.0.1 中，我们引入了新的<a href="zh/basics/import">按需引入接口</a></p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>如果之前是使用<code>import 'echarts/lib/chart/bar'</code>引入，新的接口对应的是<code>import {BarChart} from 'echarts/charts'</code>;</p>
+<p>为了方便大家了解自己的配置项需要引入哪些模块，我们新的示例编辑页面添加了生成按需引入代码的功能，大家可以在示例编辑页的<code>完整代码</code>标签下选中按需引入后查看需要引入的模块以及相关代码。</p>
+<p>在大部分情况下，我们都推荐大家尽可能用这套新的按需引入接口，它可以最大程度的利用打包工具 tree-shaking 的能力，并且可以有效解决命名空间冲突的问题而且防止了内部结构的暴露。如果你依旧在使用 CommonJS 的模块写法，之前的方式我们也依旧是支持的：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>其次，因为我们的源代码已使用 TypeScript 重写，<code>v5</code> 将不再支持从 <code>echarts/src</code> 引用文件，需要改为从<code>echarts/lib</code>引入。</p>
+<h5 id="依赖调整"><a href="#%E4%BE%9D%E8%B5%96%E8%B0%83%E6%95%B4" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>依赖调整</h5>
+<blockquote>
+<p>注意：该部分只针对为了保证较小的打包体积而是用按需引入接口的开发者，如果是全量引入的不需要关注</p>
+</blockquote>
+<p>为了保证 tree-shaking 后的体积足够小，我们去除了一些之前会默认被打包进来的依赖。比如前面提到的在使用新的按需引入接口的时候，<code>CanvasRenderer</code>将不再被默认引入，这样可以保证只需要使用 SVG 渲染模式的时候不会把不需要的 Canvas 渲染代码也一起打包进来，除此之外，还有下面这些依赖的改动：</p>
+<ul>
+<li>在使用折线图，柱状图中不再默认引入直角坐标系组件，因此之前使用下面的引入方式</li>
+</ul>

+<p><code>v5</code> 移除了内置的 geoJSON（原先在 <code>echarts/map</code> 文件夹下）。这些 geoJSON 文件本就一直来源于第三方。如果使用者仍然需要他们，可以去从老版本中得到，或者自己寻找更合适的数据然后通过 registerMap 接口注册到 ECharts 中。</p>

+<p>一些 API（包括接口调用，事件监听和配置项）在 <code>v5</code> 中不再推荐使用。当然，使用者仍然可以用他们，只是会在 dev 模式下，在 console 中打印一些 warning，并不会影响功能。但是从长远维护考虑，我们还是推荐升级成新的 API。</p>
+<p>下面是不再推荐使用的 API 以及推荐的新 API：</p>
+<ul>
+<li>图形元素 transform 相关的属性被改变了：
+<ul>
+<li>变更点：

+<li>textShadowOffsetX</li>
+<li>textShadowOffsetY</li>
+</ul>

+</li>
+<li>它影响到这些地方：
+<ul>
+<li>在 <code>graphic</code> 组件中：每个元素的声明。（原来的写法仍兼容，但在一些很复杂的情况下，可能效果不完全一致。）</li>
+<li>在自定义系列（<code>custom series</code>）中：<code>renderItem</code> 返回中的每个元素的声明。（原来的写法仍兼容，但在一些很复杂的情况下，可能效果不完全一致。）</li>

+<p>默认关闭，需要通过将 <a href="https://echarts.apache.org/option.html#aria.show" rel="nofollow noopener noreferrer" target="_blank">aria.show</a> 设置为 <code>true</code> 开启。开启后，会根据图表、数据、标题等情况，自动智能生成关于图表的描述，用户也可以通过配置项修改描述。</p>

+<p>对于有些图表，默认生成的数据点的描述并不足以表现整体的信息。比如下图的散点图，默认生成的描述可以包含数据点的坐标值，但是知道几百几千个点的坐标并不能帮助我们有效地理解图表表达的信息。</p>

+<p>除了整体性修改描述之外，我们还提供了生成描述的模板，可以方便地进行细粒度的修改。</p>
+<p>生成描述的基本流程为，如果 <a href="https://echarts.apache.org/option.html#aria.show" rel="nofollow noopener noreferrer" target="_blank">aria.show</a> 设置为 <code>true</code>，则生成无障碍访问描述，否则不生成。如果定义了 <a href="https://echarts.apache.org/option.html#aria.description" rel="nofollow noopener noreferrer" target="_blank">aria.description</a>，则将其作为图表的完整描述，否则根据模板拼接生成描述。我们提供了默认的生成描述的算法，仅当生成的描述不太合适时，才需要修改这些模板，甚至使用 <code>aria.description</code> 完全覆盖。</p>
+<p>使用模板拼接时，先根据是否存在标题 <a href="https://echarts.apache.org/option.html#title.text" rel="nofollow noopener noreferrer" target="_blank">title.text</a> 决定使用 <a href="https://echarts.apache.org/option.html#aria.general.withTitle" rel="nofollow noopener noreferrer" target="_blank">aria.general.withTitle</a> 还是 <a href="https://echarts.apache.org/option.html#aria.general.withoutTitle" rel="nofollow noopener noreferrer" target="_blank">aria.general.withoutTitle</a> 作为整体性描述。其中，<code>aria.general.w [...]
+<p>拼接完标题之后，会依次拼接系列的描述（<a href="https://echarts.apache.org/option.html#aria.series" rel="nofollow noopener noreferrer" target="_blank">aria.series</a>），和每个系列的数据的描述（<a href="https://echarts.apache.org/option.html#aria.data" rel="nofollow noopener noreferrer" target="_blank">aria.data</a>）。同样，每个模板都有可能包括模板变量，用以替换实际的值。</p>

+<p>浏览器端图表库大多会选择 SVG 或者 Canvas 进行渲染。对于绘制图表来说，这两种技术往往是可替换的，效果相近。但是在一些场景中，他们的表现和能力又有一定差异。于是，对它们的选择取舍，就成为了一个一直存在的不易有标准答案的话题。</p>
+<p>ECharts 从初始一直使用 Canvas 绘制图表。而 <a href="https://github.com/apache/echarts/releases" rel="nofollow noopener noreferrer" target="_blank">ECharts v4.0</a> 发布了 SVG 渲染器，从而提供了一种新的选择。只须在初始化一个图表实例时，设置 <a href="https://echarts.apache.org//api.html#echarts.init" rel="nofollow noopener noreferrer" target="_blank">renderer 参数</a> 为 <code>'canvas'</code> 或 <code>'svg'</code> 即可指定渲染器，比较方便。</p>
+<blockquote>
+<p>SVG 和 Canvas 这两种使用方式差异很大的技术，能够做到同时被透明支持，主要归功于 ECharts 底层库 <a href="https://github.com/ecomfe/zrender" rel="nofollow noopener noreferrer" target="_blank">ZRender</a> 的抽象和实现，形成可互换的 SVG 渲染器和 Canvas 渲染器。</p>
+</blockquote>
+<h2 id="选择哪种渲染器"><a href="#%E9%80%89%E6%8B%A9%E5%93%AA%E7%A7%8D%E6%B8%B2%E6%9F%93%E5%99%A8" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>选择哪种渲染器</h2>
+<p>一般来说，Canvas 更适合绘制图形元素数量较多（这一般是由数据量大导致）的图表（如热力图、地理坐标系或平行坐标系上的大规模线图或散点图等），也利于实现某些视觉 <a href="https://echarts.apache.org//examples/editor.html?c=lines-bmap-effect" rel="nofollow noopener noreferrer" target="_blank">特效</a>。但是，在不少场景中，SVG 具有重要的优势：它的内存占用更低（这对移动端尤其重要）、并且用户使用浏览器内置的缩放功能时不会模糊。</p>
+<p>选择哪种渲染器，我们可以根据软硬件环境、数据量、功能需求综合考虑。</p>
+<ul>
+<li>在软硬件环境较好，数据量不大的场景下，两种渲染器都可以适用，并不需要太多纠结。</li>
+<li>在环境较差，出现性能问题需要优化的场景下，可以通过试验来确定使用哪种渲染器。比如有这些经验：
+<ul>
+<li>在须要创建很多 ECharts 实例且浏览器易崩溃的情况下（可能是因为 Canvas 数量多导致内存占用超出手机承受能力），可以使用 SVG 渲染器来进行改善。大略得说，如果图表运行在低端安卓机，或者我们在使用一些特定图表如 <a href="https://ecomfe.github.io/echarts-liquidfill/example/" rel="nofollow noopener noreferrer" target="_blank">水球图</a> 等，SVG 渲染器可能效果更好。</li>
+<li>数据量较大（经验判断 > 1k）、较多交互时，建议选择 Canvas 渲染器。</li>
+</ul>
+</li>
+</ul>
+<p>我们强烈欢迎开发者们<a href="https://github.com/apache/echarts/issues/new" rel="nofollow noopener noreferrer" target="_blank">反馈</a>给我们使用的体验和场景，帮助我们更好的做优化。</p>
+<p>注：当前某些特殊的渲染依然需要依赖 Canvas：如<a href="https://echarts.apache.org/option.html#series-lines.effect" rel="nofollow noopener noreferrer" target="_blank">炫光尾迹特效</a>、<a href="https://echarts.apache.org//examples/editor.html?c=heatmap-bmap" rel="nofollow noopener noreferrer" target="_blank">带有混合效果的热力图</a>等。</p>

+<p>在<a href="zh/get-started">快速上手</a>中，我们介绍了初始化 ECharts 的接口 <a href="https://echarts.apache.org//api.html#echarts.init" rel="nofollow noopener noreferrer" target="_blank"><code>echarts.init</code></a>。<a href="https://echarts.apache.org//api.html#echarts.init" rel="nofollow noopener noreferrer" target="_blank">API 文档</a>中详细介绍了参数的具体含义，建议理解后再阅读本文。</p>
+<p>下面，我们就常见的几种使用场景，介绍如何初始化一个图表以及改变其大小。</p>
+<h2 id="初始化"><a href="#%E5%88%9D%E5%A7%8B%E5%8C%96" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>初始化</h2>
+<h3 id="在-html-中定义有宽度和高度的父容器（推荐）"><a href="#%E5%9C%A8-html-%E4%B8%AD%E5%AE%9A%E4%B9%89%E6%9C%89%E5%AE%BD%E5%BA%A6%E5%92%8C%E9%AB%98%E5%BA%A6%E7%9A%84%E7%88%B6%E5%AE%B9%E5%99%A8%EF%BC%88%E6%8E%A8%E8%8D%90%EF%BC%89" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>在 HTML 中定义有宽度和高度的父容器（推荐）</h3>
+<p>通常来说，需要在 HTML 中先定义一个 <code><div></code> 节点，并且通过 CSS 使得该节点具有宽度和高度。初始化的时候，传入该节点，图表的大小默认即为该节点的大小，除非声明了 <code>opts.width</code> 或 <code>opts.height</code> 将其覆盖。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-html line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" [...]
+<p>需要注意的是，使用这种方法在调用 <code>echarts.init</code> 时需保证容器已经有宽度和高度了。</p>
+<h3 id="指定图表的大小"><a href="#%E6%8C%87%E5%AE%9A%E5%9B%BE%E8%A1%A8%E7%9A%84%E5%A4%A7%E5%B0%8F" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>指定图表的大小</h3>
+<p>如果图表容器不存在宽度和高度，或者，你希望图表宽度和高度不等于容器大小，也可以在初始化的时候指定大小。</p>

+<p>在有些场景下，我们希望当容器大小改变时，图表的大小也相应地改变。</p>
+<p>比如，图表容器是一个高度为 300px、宽度为页面 100% 的节点，你希望在浏览器宽度改变的时候，始终保持图表宽度是页面的 100%。</p>
+<p>这种情况下，可以监听页面的 <code>window.onresize</code> 事件获取浏览器大小改变的事件，然后调用 <a href="https://echarts.apache.org/api.html#echartsInstance.resize" rel="nofollow noopener noreferrer" target="_blank"><code>echartsInstance.resize</code></a> 改变图表的大小。</p>

+<p>除了直接调用 <code>resize()</code> 不含参数的形式之外，还可以指定宽度和高度，实现图表大小不等于容器大小的效果。</p>

+<p>假设页面中存在多个标签页，每个标签页都包含一些图表。当选中一个标签页的时候，其他标签页的内容在 DOM 中被移除了。这样，当用户再选中这些标签页的时候，就会发现图表“不见”了。</p>
+<p>本质上，这是由于图表的容器节点被移除导致的。即使之后该节点被重新添加，图表所在的节点也已经不存在了。</p>
+<p>正确的做法是，在图表容器被销毁之后，调用 <a href="https://echarts.apache.org/api.html#echartsInstance.dispose" rel="nofollow noopener noreferrer" target="_blank"><code>echartsInstance.dispose</code></a> 销毁实例，在图表容器重新被添加后再次调用 <a href="https://echarts.apache.org//api.html#echarts.init" rel="nofollow noopener noreferrer" target="_blank">echarts.init</a> 初始化。</p>
+<blockquote>
+<p>小贴士：在容器节点被销毁时，总是应调用 <a href="https://echarts.apache.org/api.html#echartsInstance.dispose" rel="nofollow noopener noreferrer" target="_blank"><code>echartsInstance.dispose</code></a> 以销毁实例释放资源，避免内存泄漏。</p>

+<p>Apache ECharts<sup>TM</sup> 5 开始支持了“数据转换”（ data transform ）功能。在 echarts 中，“数据转换” 这个词指的是，给定一个已有的“数据集”（<a href="https://echarts.apache.org/option.html##dataset" rel="nofollow noopener noreferrer" target="_blank">dataset</a>）和一个“转换方法”（<a href="https://echarts.apache.org/option.html##dataset.transform" rel="nofollow noopener noreferrer" target="_blank">transform</a>），echarts 能生成一个新的“数据集”，然后可以使用这个新的“数据集”绘制图表。这些工作都可以声明式地完成。</p>
+<p>抽象地来说，数据转换是这样一种公式：<code>outData = f(inputData)</code>。<code>f</code> 是转换方法，例如：<code>filter</code>、<code>sort</code>、<code>regression</code>、<code>boxplot</code>、<code>cluster</code>、<code>aggregate</code>(todo) 等等。有了数据转换能力后，我们就至少可以做到这些事情：</p>
+<ul>
+<li>把数据分成多份用不同的饼图展现。</li>
+<li>进行一些数据统计运算，并展示结果。</li>
+<li>用某些数据可视化算法处理数据，并展示结果。</li>
+<li>数据排序。</li>
+<li>去除或直选择数据项。</li>
+<li>...</li>
+</ul>
+<h2 id="数据转换基础使用"><a href="#%E6%95%B0%E6%8D%AE%E8%BD%AC%E6%8D%A2%E5%9F%BA%E7%A1%80%E4%BD%BF%E7%94%A8" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据转换基础使用</h2>
+<p>在 echarts 中，数据转换是依托于数据集（<a href="https://echarts.apache.org/option.html##dataset" rel="nofollow noopener noreferrer" target="_blank">dataset</a>）来实现的. 我们可以设置 <a href="https://echarts.apache.org/option.html##dataset.transform" rel="nofollow noopener noreferrer" target="_blank">dataset.transform</a> 来表示，此 dataset 的数据，来自于此 transform 的结果。例如。</p>
+<p>下面是上述例子的效果，三个饼图分别显示了 2011、2012、2013 年的数据。</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>现在我们简单总结下，使用 transform 时的几个要点：</p>
+<ul>
+<li>在一个空的 dataset 中声明 <code>transform</code>, <code>fromDatasetIndex</code>/<code>fromDatasetId</code> 来表示我们要生成新的数据。</li>
+<li>系列引用这个 dataset 。</li>
+</ul>
+<h2 id="数据转换的进阶使用"><a href="#%E6%95%B0%E6%8D%AE%E8%BD%AC%E6%8D%A2%E7%9A%84%E8%BF%9B%E9%98%B6%E4%BD%BF%E7%94%A8" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据转换的进阶使用</h2>
+<h4 id="链式声明-transform"><a href="#%E9%93%BE%E5%BC%8F%E5%A3%B0%E6%98%8E-transform" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>链式声明 transform</h4>
+<p><code>transform</code> 可以被链式声明，这是一个语法糖。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<blockquote>
+<p>注意：理论上，任何 transform 都可能有多个输入或多个输出。但是，如果一个 transform 被链式声明，它只能获取前一个 transform 的第一个输出作为输入（第一个 transform 除外），以及它只能把自己的第一个输出给到后一个 transform （最后一个 transform 除外）。</p>
+</blockquote>
+<h4 id="一个-transform-输出多个-data"><a href="#%E4%B8%80%E4%B8%AA-transform-%E8%BE%93%E5%87%BA%E5%A4%9A%E4%B8%AA-data" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>一个 transform 输出多个 data</h4>
+<p>在大多数场景下，transform 只需输出一个 data 。但是也有一些场景，需要输出多个 data ，每个 data 可以被不同的 series 或者 dataset 所使用。</p>
+<p>例如，在内置的 "boxplot" transform 中，除了 boxplot 系列所需要的 data 外，离群点（ outlier ）也会被生成，并且可以用例如散点图系列显示出来。例如，<a href="https://echarts.apache.org/examples/zh/editor.html?c=boxplot-light-velocity" rel="nofollow noopener noreferrer" target="_blank">example</a>。</p>
+<p>我们提供配置 <a href="https://echarts.apache.org/option.html##dataset.fromTransformResult" rel="nofollow noopener noreferrer" target="_blank">dataset.fromTransformResult</a> 来满足这种情况，例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>另外，<a href="https://echarts.apache.org/option.html##dataset.fromTransformResult" rel="nofollow noopener noreferrer" target="_blank">dataset.fromTransformResult</a> 和 <a href="https://echarts.apache.org/option.html##dataset.transform" rel="nofollow noopener noreferrer" target="_blank">dataset.transform</a> 能同时出现在一个 dataset 中，这表示，这个 transform 的输入，是上游的结果中以 <code>fromTransformResult</code> 获取的结果。例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h4 id="在开发环境中-debug"><a href="#%E5%9C%A8%E5%BC%80%E5%8F%91%E7%8E%AF%E5%A2%83%E4%B8%AD-debug" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>在开发环境中 debug</h4>
+<p>使用 transform 时，有时候我们会配不对，显示不出来结果，并且不知道哪里错了。所以，这里提供了一个配置项 <code>transform.print</code> 方便 debug 。这个配置项只在开发环境中生效。如下例：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="数据转换器-filter"><a href="#%E6%95%B0%E6%8D%AE%E8%BD%AC%E6%8D%A2%E5%99%A8-filter" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据转换器 "filter"</h2>
+<p>echarts 内置提供了能起过滤作用的数据转换器。我们只需声明 <code>transform.type: "filter"</code>，以及给出数据筛选条件。如下例：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>这是 filter 的另一个例子的效果：</p>
+<iframe width="100%" height="350" src="https://echarts.apache.org/examples/zh/view.html?c=data-transform-filter"></iframe>
+<p>在 "filter" transform 中，有这些要素：</p>
+<p><strong>关于维度（ dimension ）：</strong></p>
+<p><code>config.dimension</code> 指定了维度，能设成这样的值：</p>
+<ul>
+<li>设定成声明在 dataset 中的维度名，例如 <code>config: { dimension: 'Year', '=': 2011 }</code>。不过， dataset 中维度名的声明并非强制，所以我们也可以</li>
+<li>设定成 dataset 中的维度 index （index 值从 0 开始）例如 <code>config: { dimension: 3, '=': 2011 }</code>。</li>
+</ul>
+<p><strong>关于关系比较操作符：</strong></p>
+<p>关系操作符，可以设定这些：
+<code>></code>（<code>gt</code>）、<code>>=</code>（<code>gte</code>）、<code><</code>（<code>lt</code>）、<code><=</code>（<code>lte</code>）、<code>=</code>（<code>eq</code>）、<code>!=</code>（<code>ne</code>、<code><></code>）、<code>reg</code>。（小括号中的符号或名字，是别名，设置起来作用相同）。他们首先基本地能基于数值大小进行比较，然后也有些额外的功能特性：</p>
+<ul>
+<li>多个关系操作符能声明在一个 {} 中，例如 <code>{ dimension: 'Price', '>=': 20, '<': 30 }</code>。这表示“与”的关系，即，筛选出价格大于等于 20 小雨 30 的数据项。</li>
+<li>data 里的值，不仅可以是数值（ number ），也可以是“类数值的字符串”（“ numeric string ”）。“类数值的字符串”本身是一个字符串，但是可以被转换为字面所描述的数值，例如 <code>' 123 '</code>。转换过程中，空格（全角半角空格）和换行符都能被消除（ trim ）。</li>
+<li>如果我们需要对日期对象（JS <code>Date</code>）或者日期字符串（如 '2012-05-12'）进行比较，我们需要手动指定 <code>parser: 'time'</code>，例如 <code>config: { dimension: 3, lt: '2012-05-12', parser: 'time' }</code>。</li>
+<li>纯字符串比较也被支持，但是只能用在 <code>=</code> 或 <code>!=</code> 上。而 <code>></code>, <code>>=</code>, <code><</code>, <code><=</code> 并不支持纯字符串比较，也就是说，这四个操作符的右值，不能是字符串。</li>
+<li><code>reg</code> 操作符能提供正则表达式比较。例如， <code>{ dimension: 'Name', reg: /\s+Müller\s*$/ }</code> 能在 <code>'Name'</code> 维度上选出姓 <code>'Müller'</code> 的数据项。</li>
+</ul>
+<p><strong>关于逻辑比较：</strong></p>
+<p>我们也支持了逻辑比较操作符 <strong>与或非</strong>（ <code>and</code> | <code>or</code> | <code>not</code> ）：</p>

+<p><strong>关于解析器（ parser ）：</strong></p>
+<p>还可以指定“解析器”（ parser ）来对值进行解析后再做比较。现在支持的解析器有：</p>
+<ul>
+<li><code>parser: 'time'</code>：把原始值解析成时间戳（ timestamp ）后再做比较。这个解析器的行为，和 <code>echarts.time.parse</code> 相同，即，当原始值为时间对象（ JS <code>Date</code> 实例），或者是时间戳，或者是描述时间的字符串（例如 <code>'2012-05-12 03:11:22'</code> ），都可以被解析为时间戳，然后就可以基于数值大小进行比较。如果原始数据是其他不可解析为时间戳的值，那么会被解析为 NaN。</li>
+<li><code>parser: 'trim'</code>：如果原始数据是字符串，则把字符串两端的空格（全角半角）和换行符去掉。如果不是字符串，还保持为原始数据。</li>
+<li><code>parser: 'number'</code>：强制把原始数据转成数值。如果不能转成有意义的数值，那么转成 <code>NaN</code>。在大多数场景下，我们并不需要这个解析器，因为按默认策略，“像数值的字符串”就会被转成数值。但是默认策略比较严格，这个解析器比较宽松，如果我们遇到含有尾缀的字符串（例如 <code>'33%'</code>, <code>12px</code>），我们需要手动指定 <code>parser: 'number'</code>，从而去掉尾缀转为数值才能比较。</li>
+</ul>
+<p>这个例子显示了如何使用 <code>parser: 'time'</code>：</p>

+<p>"sort" 是另一个内置的数据转换器，用于排序数据。目前主要能用于在类目轴（ <code>axis.type: 'category'</code> ）中显示排过序的数据。例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<iframe width="100%" height="350" src="https://echarts.apache.org/examples/zh/view.html?c=data-transform-sort-bar"></iframe>
+<p>数据转换器 "sort" 还有一些额外的功能：</p>
+<ul>
+<li>可以多重排序，多个维度一起排序。见下面的例子。</li>
+<li>排序规则是这样的：
+<ul>
+<li>默认按照数值大小排序。其中，“可转为数值的字符串”也被转换成数值，和其他数值一起按大小排序。</li>
+<li>对于其他“不能转为数值的字符串”，也能在它们之间按字符串进行排序。这个特性有助于这种场景：把相同标签的数据项排到一起，尤其是当多个维度共同排序时。见下面的例子。</li>
+<li>当“数值及可转为数值的字符串”和“不能转为数值的字符串”进行排序时，或者它们和“其他类型的值”进行比较时，它们本身是不知如何进行比较的。那么我们称呼“后者”为“incomparable”，并且可以设置 <code>incomparable: 'min' | 'max'</code> 来指定一个“incomparable”在这个比较中是最大还是最小，从而能使它们能产生比较结果。这个设定的用途，比如可以是，决定空值（例如 <code>null</code>, <code>undefined</code>, <code>NaN</code>, <code>''</code>, <code>'-'</code>）在排序的头还是尾。</li>
+</ul>
+</li>
+<li>过滤器 <code>filter: 'time' | 'trim' | 'number'</code> 可以被使用，和数据转换器 "filter" 中的情况一样。
+<ul>
+<li>如果要对时间进行排序（例如，值为 JS <code>Date</code> 实例或者时间字符串如 <code>'2012-03-12 11:13:54'</code>），我们需要声明 <code>parser: 'time'</code>。</li>
+<li>如果需要对有后缀的数值进行排序（如 <code>'33%'</code>, <code>'16px'</code>）我们需要声明 <code>parser: 'number'</code>。</li>
+</ul>
+</li>
+</ul>
+<p>这是一个“多维度排序”的例子。</p>

+<p><code>数据集</code>（<code>dataset</code>）是专门用来管理数据的组件。虽然每个系列都可以在 <code>series.data</code> 中设置数据，但是从 ECharts4 支持 <code>数据集</code> 开始，更推荐使用 <code>数据集</code> 来管理数据。因为这样，数据可以被多个组件复用，也方便进行 “数据和其他配置” 分离的配置风格。毕竟，在运行时，数据是最常改变的，而其他配置大多并不会改变。</p>
+<h2 id="在系列中设置数据"><a href="#%E5%9C%A8%E7%B3%BB%E5%88%97%E4%B8%AD%E8%AE%BE%E7%BD%AE%E6%95%B0%E6%8D%AE" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>在系列中设置数据</h2>
+<p>如果数据设置在 <code>系列</code>（<code>series</code>）中，例如：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<p>这种方式的优点是，适于对一些特殊的数据结构（如“树”、“图”、超大数据）进行一定的数据类型定制。
+但是缺点是，常需要用户先处理数据，把数据分割设置到各个系列（和类目轴）中。此外，不利于多个系列共享一份数据，也不利于基于原始数据进行图表类型、系列的映射安排。</p>

+<p>而数据设置在 <code>数据集</code>（<code>dataset</code>）中，会有这些好处：</p>
+<ul>
+<li>能够贴近数据可视化常见思维方式：（I）提供数据，（II）指定数据到视觉的映射，从而形成图表。</li>
+<li>数据和其他配置可以被分离开来。数据常变，其他配置常不变。分开易于分别管理。</li>

+<p>如上所述，数据可视化的一个常见思路是：（I）提供数据，（II）指定数据到视觉的映射。</p>
+<p>简而言之，可以进行这些映射的设定：</p>
+<ul>
+<li>指定 <code>数据集</code> 的列（column）还是行（row）映射为 <code>系列</code>（<code>series</code>）。这件事可以使用 <a href="https://echarts.apache.org/option.html##series.seriesLayoutBy" rel="nofollow noopener noreferrer" target="_blank">series.seriesLayoutBy</a> 属性来配置。默认是按照列（column）来映射。</li>
+<li>指定维度映射的规则：如何从 dataset 的维度（一个“维度”的意思是一行/列）映射到坐标轴（如 X、Y 轴）、提示框（tooltip）、标签（label）、图形元素大小颜色等（visualMap）。这件事可以使用 <a href="https://echarts.apache.org/option.html##series.encode" rel="nofollow noopener noreferrer" target="_blank">series.encode</a> 属性，以及 <a href="https://echarts.apache.org/option.html##visualMap" rel="nofollow noopener noreferrer" target="_blank">visualMap</a> 组件来配置（如果有需要映射颜色大小等视觉维度的话）。上面的例子中，没有给出这种映射配置，那么 ECharts 就按最常见的理解进行默认映射：X 坐标轴声明为类目轴，默认情况下会自动对应到 <code>dataset.source< [...]
+</ul>
+<p>下面详细解释这些映射的设定。</p>
+<h2 id="把数据集（-dataset-）的行或列映射为系列（series）"><a href="#%E6%8A%8A%E6%95%B0%E6%8D%AE%E9%9B%86%EF%BC%88-dataset-%EF%BC%89%E7%9A%84%E8%A1%8C%E6%88%96%E5%88%97%E6%98%A0%E5%B0%84%E4%B8%BA%E7%B3%BB%E5%88%97%EF%BC%88series%EF%BC%89" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>把数据集（ dataset ）的行或列映射为系列（series）</h2>
+<p>有了数据表之后，使用者可以灵活地配置：数据如何对应到轴和图形系列。</p>
+<p>用户可以使用 <code>seriesLayoutBy</code> 配置项，改变图表对于行列的理解。<code>seriesLayoutBy</code> 可取值：</p>
+<ul>
+<li>'column': 默认值。系列被安放到 <code>dataset</code> 的列上面。</li>
+<li>'row': 系列被安放到 <code>dataset</code> 的行上面。</li>
+</ul>
+<p>看这个例子：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="维度（-dimension-）"><a href="#%E7%BB%B4%E5%BA%A6%EF%BC%88-dimension-%EF%BC%89" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>维度（ dimension ）</h2>
+<p>常用图表所描述的数据大部分是“二维表”结构，上述的例子中，我们都使用二维数组来容纳二维表。现在，当我们把系列（ series ）对应到“列”的时候，那么每一列就称为一个“维度（ dimension ）”，而每一行称为数据项（ item ）。反之，如果我们把系列（ series ）对应到表行，那么每一行就是“维度（ dimension ）”，每一列就是数据项（ item ）。</p>
+<p>维度可以有单独的名字，便于在图表中显示。维度名（ dimension name ）可以在定义在 dataset 的第一行（或者第一列）。例如上面的例子中，<code>'score'</code>、<code>'amount'</code>、<code>'product'</code> 就是维度名。从第二行开始，才是正式的数据。<code>dataset.source</code> 中第一行（列）到底包含不包含维度名，ECharts 默认会自动探测。当然也可以设置 <code>dataset.sourceHeader: true</code> 显示声明第一行（列）就是维度，或者 <code>dataset.sourceHeader: false</code> 表明第一行（列）开始就直接是数据。</p>
+<p>维度的定义，也可以使用单独的 <code>dataset.dimensions</code> 或者 <code>series.dimensions</code> 来定义，这样可以同时指定维度名，和维度的类型（ dimension type ）：</p>

+<p>大多数情况下，我们并不需要去设置维度类型，因为 ECharts 会自动尝试判断。但是如果不足够准确时，可以手动设置维度类型。</p>
+<p>维度类型（ dimension type ）可以取这些值：</p>
+<ul>
+<li><code>'number'</code>: 默认，表示普通数据。</li>
+<li><code>'ordinal'</code>: 对于类目、文本这些 string 类型的数据，如果需要能在数轴上使用，须是 'ordinal' 类型。ECharts 默认会试图自动判断这个类型。但是自动判断也可能不准确，所以使用者也可以手动强制指定。</li>
+<li><code>'time'</code>: 表示时间数据。设置成 <code>'time'</code> 则能支持自动解析数据成时间戳（timestamp），比如该维度的数据是 '2017-05-10'，会自动被解析。如果这个维度被用在时间数轴（<a href="https://echarts.apache.org/option.html##xAxis.type" rel="nofollow noopener noreferrer" target="_blank">axis.type</a> 为 <code>'time'</code>）上，那么会被自动设置为 <code>'time'</code> 类型。时间类型的支持参见 <a href="https://echarts.apache.org/option.html##series.data" rel="nofollow noopener noreferrer" target="_blank">data</a>。</li>
+<li><code>'float'</code>: 如果设置成 <code>'float'</code>，在存储时候会使用 <code>TypedArray</code>，对性能优化有好处。</li>
+<li><code>'int'</code>: 如果设置成 <code>'int'</code>，在存储时候会使用 <code>TypedArray</code>，对性能优化有好处。</li>

+<p>值得一提的是，当 <code>series.encode</code> 并没有指定时，ECharts 针对最常见直角坐标系中的图表（折线图、柱状图、散点图、K 线图等）、饼图、漏斗图，会采用一些默认的映射规则。默认的映射规则比较简单，大体是：</p>
+<ul>
+<li>在坐标系中（如直角坐标系、极坐标系等）
+<ul>
+<li>如果有类目轴（axis.type 为 'category'），则将第一列（行）映射到这个轴上，后续每一列（行）对应一个系列。</li>
+<li>如果没有类目轴，假如坐标系有两个轴（例如直角坐标系的 X Y 轴），则每两列对应一个系列，这两列分别映射到这两个轴上。</li>
+</ul>
+</li>
+<li>如果没有坐标系（如饼图）
+<ul>
+<li>取第一列（行）为名字，第二列（行）为数值（如果只有一列，则取第一列为数值）。</li>
+</ul>
+</li>
+</ul>
+<p>默认的规则不能满足要求时，就可以自己来配置 <code>encode</code>，也并不复杂。这是一个 <a href="https://echarts.apache.org/examples/zh/editor.html?c=dataset-default&edit=1&reset=1" rel="nofollow noopener noreferrer" target="_blank">例子</a>。</p>

+<p>多数常见图表中，数据适于用二维表的形式描述。广为使用的数据表格软件（如 MS Excel、Numbers）或者关系数据数据库都是二维表。他们的数据可以导出成 JSON 格式，输入到 <code>dataset.source</code> 中，在不少情况下可以免去一些数据处理的步骤。</p>
+<blockquote>
+<p>假如数据导出成 csv 文件，那么可以使用一些 csv 工具如 <a href="https://github.com/d3/d3-dsv" rel="nofollow noopener noreferrer" target="_blank">dsv</a> 或者 <a href="https://github.com/mholt/PapaParse" rel="nofollow noopener noreferrer" target="_blank">PapaParse</a> 将 csv 转成 JSON。</p>
+</blockquote>
+<p>在 JavaScript 常用的数据传输格式中，二维数组可以比较直观的存储二维表。前面的示例都是使用二维数组表示。</p>
+<p>除了二维数组以外，dataset 也支持例如下面 key-value 方式的数据格式，这类格式也非常常见。但是这类格式中，目前并不支持 <a href="https://echarts.apache.org/option.html##series.seriesLayoutBy" rel="nofollow noopener noreferrer" target="_blank">seriesLayoutBy</a> 参数。</p>

+<p>上面提到诸如 <code>'legendselectchanged'</code> 事件会由组件交互的行为触发，那除了用户的交互操作，有时候也会有需要在程序里调用方法触发图表的行为，诸如显示 tooltip，选中图例。</p>
+<p>在 ECharts 通过调用 <code>myChart.dispatchAction({ type: '' })</code> 触发图表行为，统一管理了所有动作，也可以方便地根据需要去记录用户的行为路径。</p>
+<p>常用的动作和动作对应参数在 <a href="https://echarts.apache.org//api.html#action" rel="nofollow noopener noreferrer" target="_blank">action</a> 文档中有列出。</p>
+<p>下面示例演示了如何通过 <code>dispatchAction</code> 去轮流高亮饼图的每个扇形。</p>

+<p>有时候，开发者需要监听画布的“空白处”所触发的事件。比如，当需要在用户点击“空白处”的时候重置图表时。</p>
+<p>在讨论这个功能之前，我们需要先明确两种事件。zrender 事件和 echarts 事件。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>zrender 事件与 echarts 事件不同。前者是当鼠标在任何地方都会被触发，而后者是只有当鼠标在图形元素上时才能被触发。事实上，echarts 事件是在 zrender 事件的基础上实现的，也就是说，当一个 zrender 事件在图形元素上被触发时，echarts 将触发一个 echarts 事件给开发者。</p>
+<p>有了 zrender 事件，我们就可以实现监听空白处的事件，具体如下：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]

+<p>本文主要是大略概述，用哪些方法，可以在 Apache ECharts<sup>TM</sup> 中设置样式，改变图形元素或者文字的颜色、明暗、大小等。</p>
+<blockquote>
+<p>之所以用“样式”这种可能不很符合数据可视化思维的词，是因为，比较通俗易懂。</p>
+</blockquote>
+<p>本文介绍这几种方式，他们的功能范畴可能会有交叉（即同一种细节的效果可能可以用不同的方式实现），但是他们各有各的场景偏好。</p>
+<ul>
+<li>颜色主题（Theme）</li>
+<li>调色盘</li>
+<li>直接样式设置（itemStyle、lineStyle、areaStyle、label、...）</li>
+<li>视觉映射（visualMap）</li>
+</ul>
+<h2 id="颜色主题（theme）"><a href="#%E9%A2%9C%E8%89%B2%E4%B8%BB%E9%A2%98%EF%BC%88theme%EF%BC%89" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>颜色主题（Theme）</h2>
+<p>最简单的更改全局样式的方式，是直接采用颜色主题（theme）。例如，在 <a href="$%7BwebsitePath%7D/examples">示例集合</a> 中，可以通过切换深色模式，直接看到采用主题的效果。</p>
+<p>ECharts5 除了一贯的默认主题外，还内置了<code>'dark'</code>主题。可以如下切换成深色模式：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>其他的主题，没有内置在 ECharts 中，需要自己加载。这些主题可以在 <a href="https://echarts.apache.org/theme-builder.html" rel="nofollow noopener noreferrer" target="_blank">主题编辑器</a> 里访问到。也可以使用这个主题编辑器，自己编辑主题。下载下来的主题可以这样使用：</p>
+<p>如果主题保存为 JSON 文件，那么可以自行加载和注册，例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>如果保存为 UMD 格式的 JS 文件，那么支持了自注册，直接引入 JS 文件即可：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="调色盘"><a href="#%E8%B0%83%E8%89%B2%E7%9B%98" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>调色盘</h2>
+<p>调色盘，可以在 option 中设置。它给定了一组颜色，图形、系列会自动从其中选择颜色。
+可以设置全局的调色盘，也可以设置系列自己专属的调色盘。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="直接的样式设置-itemstyle-linestyle-areastyle-label-"><a href="#%E7%9B%B4%E6%8E%A5%E7%9A%84%E6%A0%B7%E5%BC%8F%E8%AE%BE%E7%BD%AE-itemstyle-linestyle-areastyle-label-" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>直接的样式设置 itemStyle, lineStyle, areaStyle, label, ...</h2>
+<p>直接的样式设置是比较常用设置方式。纵观 ECharts 的 <a href="https://echarts.apache.org/option.html#" rel="nofollow noopener noreferrer" target="_blank">option</a> 中，很多地方可以设置 <a href="https://echarts.apache.org/option.html#series-bar.itemStyle" rel="nofollow noopener noreferrer" target="_blank">itemStyle</a>、<a href="https://echarts.apache.org/option.html#series-line.lineStyle" rel="nofollow noopener noreferrer" target="_blank">lineStyle</a>、<a href="https://echarts.apache.org/option.html#series-line.areaS [...]
+<p>一般来说，ECharts 的各个系列和组件，都遵从这些命名习惯，虽然不同图表和组件中，<code>itemStyle</code>、<code>label</code> 等可能出现在不同的地方。</p>
+<p>在下面例子中我们给气泡图设置了阴影，渐变色等复杂的样式，你可以修改代码中的样式看修改后的效果：</p>
+<div class="nuxt-content-highlight"><!----></div>
+<h2 id="高亮的样式：emphasis"><a href="#%E9%AB%98%E4%BA%AE%E7%9A%84%E6%A0%B7%E5%BC%8F%EF%BC%9Aemphasis" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>高亮的样式：emphasis</h2>
+<p>在鼠标悬浮到图形元素上时，一般会出现高亮的样式。默认情况下，高亮的样式是根据普通样式自动生成的。但是高亮的样式也可以自己定义，主要是通过 <a href="https://echarts.apache.org/option.html#series-bar.emphasis" rel="nofollow noopener noreferrer" target="_blank">emphasis</a> 属性来定制。<a href="https://echarts.apache.org/option.html#series-bar.emphasis" rel="nofollow noopener noreferrer" target="_blank">emphsis</a> 中的结构，和普通样式的结构相同，例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>注意：在 ECharts4 以前，高亮和普通样式的写法，是这样的：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>这种写法 <strong>仍然被兼容</strong>，但是，不再推荐。事实上，多数情况下，使用者只会配置普通状态下的样式，而使用默认的高亮样式。所以在 ECharts4 中，支持不写 <code>normal</code> 的配置方法（即本文开头的那种写法），使得配置项更扁平简单。</p>

+<p>数据可视化是数据到视觉元素的映射过程（这个过程也可称为视觉编码，视觉元素也可称为视觉通道）。</p>
+<p>ECharts 的每种图表本身就内置了这种映射过程，比如折线图把数据映射到“线”，柱状图把数据映射到“长度”。一些更复杂的图表，如关系图、事件河流图、树图也都会做出各自内置的映射。</p>
+<p>此外，ECharts 还提供了 <a href="https://echarts.apache.org/option.html#visualMap" rel="nofollow noopener noreferrer" target="_blank">visualMap 组件</a> 来提供通用的视觉映射。<code>visualMap</code> 组件中可以使用的视觉元素有：</p>
+<ul>
+<li>图形类别（symbol）、图形大小（symbolSize）</li>
+<li>颜色（color）、透明度（opacity）、颜色透明度（colorAlpha）、</li>
+<li>颜色明暗度（colorLightness）、颜色饱和度（colorSaturation）、色调（colorHue）</li>
+</ul>
+<p>下面对 <code>visualMap</code> 组件的使用方式进行简要的介绍。</p>
+<h2 id="数据和维度"><a href="#%E6%95%B0%E6%8D%AE%E5%92%8C%E7%BB%B4%E5%BA%A6" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>数据和维度</h2>
+<p>ECharts 中的数据，一般存放于 <a href="https://echarts.apache.org/option.html#series.data" rel="nofollow noopener noreferrer" target="_blank"><code>series.data</code></a> 中。根据图表类型不同，数据的具体形式也可能有些许差异。比如可能是“线性表“、“树“、“图“等。但他们都有个共性：都是“数据项（dataItem）“的集合。每个数据项含有“数据值（value）“和其他信息（如果需要的话）。每个数据值，可以是单一的数值（一维）或者一个数组（多维）。</p>
+<p>例如，<a href="https://echarts.apache.org/option.html#series.data" rel="nofollow noopener noreferrer" target="_blank">series.data</a> 最常见的形式，是“线性表“，即一个普通数组：</p>

+<p>在图表中，往往默认把 value 的前一两个维度进行映射，比如取第一个维度映射到 x 轴，取第二个维度映射到 y 轴。如果想要把更多的维度展现出来，可以借助 <code>visualMap</code>。最常见的情况，<a href="https://echarts.apache.org/option.html#series-scatter" rel="nofollow noopener noreferrer" target="_blank">散点图（scatter）</a> 使用半径展现了第三个维度。</p>
+<h2 id="visualmap-组件"><a href="#visualmap-%E7%BB%84%E4%BB%B6" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>visualMap 组件</h2>
+<p>visualMap 组件定义了把数据的<em>哪个维度</em>映射到<em>什么视觉元素上</em>。</p>
+<p>现在提供如下两种类型的 visualMap 组件，通过 <a href="https://echarts.apache.org/option.html#visualMap.type" rel="nofollow noopener noreferrer" target="_blank">visualMap.type</a> 来区分。</p>
+<p>其定义结构例如：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<h2 id="连续型与分段型视觉映射组件"><a href="#%E8%BF%9E%E7%BB%AD%E5%9E%8B%E4%B8%8E%E5%88%86%E6%AE%B5%E5%9E%8B%E8%A7%86%E8%A7%89%E6%98%A0%E5%B0%84%E7%BB%84%E4%BB%B6" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>连续型与分段型视觉映射组件</h2>
+<p>ECharts 的视觉映射组件分为连续型（<a href="https://echarts.apache.org/option.html#visualMap-continuous" rel="nofollow noopener noreferrer" target="_blank">visualMapContinuous</a>）与分段型（<a href="https://echarts.apache.org/option.html#visualMap-piecewise" rel="nofollow noopener noreferrer" target="_blank">visualMapPiecewise</a>）。</p>
+<p>连续型的意思是，进行视觉映射的数据维度是连续的数值；而分段型则是数据被分成了多段或者是离散型的数据。</p>
+<h3 id="连续型视觉映射"><a href="#%E8%BF%9E%E7%BB%AD%E5%9E%8B%E8%A7%86%E8%A7%89%E6%98%A0%E5%B0%84" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>连续型视觉映射</h3>
+<p>连续型视觉映射通过指定最大值、最小值，就可以确定视觉映射的范围。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-js line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" s [...]
+<p>其中，<a href="https://echarts.apache.org/option.html#visualMap.inRange" rel="nofollow noopener noreferrer" target="_blank">visualMap.inRange</a> 表示在数据映射范围内的数据采用的样式；而 <a href="https://echarts.apache.org/option.html#visualMap.outOfRange" rel="nofollow noopener noreferrer" target="_blank">visualMap.outOfRange</a> 则指定了超出映射范围外的数据的样式。</p>
+<p><a href="~visualMap.dimension">visualMap.dimension</a> 则指定了将数据的哪个维度做视觉映射。</p>
+<h3 id="分段型视觉映射"><a href="#%E5%88%86%E6%AE%B5%E5%9E%8B%E8%A7%86%E8%A7%89%E6%98%A0%E5%B0%84" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>分段型视觉映射</h3>
+<p>分段型视觉映射组件有三种模式：</p>
+<ul>
+<li>连续型数据平均分段：依据 <a href="https://echarts.apache.org/option.html#visualMap-piecewise.splitNumber" rel="nofollow noopener noreferrer" target="_blank">visualMap-piecewise.splitNumber</a> 来自动平均分割成若干块。</li>
+<li>连续型数据自定义分段：依据 <a href="https://echarts.apache.org/option.html#visualMap-piecewise.pieces" rel="nofollow noopener noreferrer" target="_blank">visualMap-piecewise.pieces</a> 来定义每块范围。</li>
+<li>离散数据（类别性数据）：类别定义在 <a href="https://echarts.apache.org/option.html#visualMap-piecewise.categories" rel="nofollow noopener noreferrer" target="_blank">visualMap-piecewise.categories</a> 中。</li>
+</ul>
+<p>使用分段型视觉映射时，需要将 <code>type</code> 设为 <code>'piecewise'</code>，并且将上面的三个配置项选其一配置即可，其他配置项类似连续型视觉映射。</p></div> <div class="table-of-contents"><h4 class="toc-container-header">本页目录</h4> <ul><li class="toc2"><a href="/echarts-handbook/zh/concepts/visual-map#%E6%95%B0%E6%8D%AE%E5%92%8C%E7%BB%B4%E5%BA%A6">数据和维度</a></li><li class="toc2"><a href="/echarts-handbook/zh/concepts/visual-map#visualmap-%E7%BB%84%E4%BB%B6">visualMap 组件</a></li><li class="toc2"><a href="/echarts-handbook/zh/concepts/vis [...]

+<p>Apache ECharts 支持多种下载方式，可以在下一篇教程<a href="zh/basics/download">安装</a>中查看所有方式。这里，我们以从 <a href="https://www.jsdelivr.com/package/npm/echarts" rel="nofollow noopener noreferrer" target="_blank">jsDelivr</a> CDN 上获取为例，介绍如何快速安装。</p>
+<p>在 <a href="https://www.jsdelivr.com/package/npm/echarts" rel="nofollow noopener noreferrer" target="_blank">https://www.jsdelivr.com/package/npm/echarts</a> 选择 <code>dist/echarts.js</code>，点击并保存为 <code>echarts.js</code> 文件。</p>

+<h2 id="引入-apache-echarts"><a href="#%E5%BC%95%E5%85%A5-apache-echarts" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>引入 Apache ECharts</h2>
+<p>在刚才保存 <code>echarts.js</code> 的目录新建一个 <code>index.html</code> 文件，内容如下：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-html line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" [...]
+<p>打开这个 <code>index.html</code>，你会看到一片空白。但是不要担心，打开控制台确认没有报错信息，就可以进行下一步。</p>
+<h2 id="绘制一个简单的图表"><a href="#%E7%BB%98%E5%88%B6%E4%B8%80%E4%B8%AA%E7%AE%80%E5%8D%95%E7%9A%84%E5%9B%BE%E8%A1%A8" aria-hidden="true" tabindex="-1"><span class="icon icon-link"></span></a>绘制一个简单的图表</h2>
+<p>在绘图前我们需要为 ECharts 准备一个定义了高宽的 DOM 容器。在刚才的例子 <code></head></code> 之后，添加：</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-html line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" [...]
+<p>然后就可以通过 <a href="https://echarts.apache.org//api.html#echarts.init" rel="nofollow noopener noreferrer" target="_blank">echarts.init</a> 方法初始化一个 echarts 实例并通过 <a href="https://echarts.apache.org//api.html#echartsInstance.setOption" rel="nofollow noopener noreferrer" target="_blank">setOption</a> 方法生成一个简单的柱状图，下面是完整代码。</p>
+<div class="nuxt-content-highlight"><div class="md-code-block"><div class="nuxt-content-highlight"><pre class="language-html line-numbers"><code></code></pre></div> <!----> <div class="clipboard" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" class="h-6 w-6" data-v-479657ca><path stroke-linecap="round" [...]
