[GitHub] [incubator-echarts] czzonet opened a new issue #13347: area-category--dimension 0: Cannot read property 'coord' of undefined...at getVisualGradient (LineView.js?f17f:228)||折线面积图用类别报错和无法渲染面积的颜色
czzonet opened a new issue #13347:
URL: https://github.com/apache/incubator-echarts/issues/13347
### Version
4.9.0
### Steps to reproduce
[Examples - Apache ECharts (incubating)](https://echarts.apache.org/examples/zh/editor.html?c=area-pieces)
Error when using dimension: 0 in area-category: undefined coord.Other dimension no error.
But both can not draw area, just draw symbol.
```js
option = {
dataset: {
source:[
["x", "y", "z", "t"],
["2019-10-10", 200, 700, "a"],
["2019-10-11", 400, 600, "a"],
["2019-10-12", 650, 500, "a"],
["2019-10-13", 500, 400, "a"],
["2019-10-14", 250, 300, "a"],
["2019-10-15", 300, 200, "a"],
["2019-10-16", 450, 300, "b"],
["2019-10-17", 300, 400, "a"],
["2019-10-18", 100, 500, "a"],
],
},
xAxis: {
type: 'category',
},
yAxis: {
type: 'value',
},
visualMap: {
type: "piecewise",
top: 10,
left: 10,
// dimension: 3,
dimension: 0,
seriesIndex: 0,
show: true,
// categories: ["a", "b"],
categories: ["1", "2"],
// categories: ["2019-10-10", "2019-10-11"],
inRange: {
color: ["blue", "gold"],
},
outOfRange: {
color: "red",
},
},
series: [
{
type: 'line',
smooth: 0.6,
lineStyle: {
color: 'green',
width: 5
},
areaStyle: {},
encode: {
x: 0,
y: 1,
},
}
]
};
```
### What is expected?
draw area with color
### What is actually happening?
undefined error, and just draw symbol
---
In LineView.js, `visualMeta.stops` is empty when using dimension: 0.
But, pieces draw well.
