[GitHub] [incubator-echarts] JesseEisen opened a new issue #13644: X 轴 value 类型，如何自定义设置非均匀刻度值(科学计数法)，希望图表能够按照这个刻度去绘制。
JesseEisen opened a new issue #13644:
URL: https://github.com/apache/incubator-echarts/issues/13644
### Version
4.9.0
### Steps to reproduce
在 X 轴（value 类型）上数据差异很大的时候，比如 10E-8 和 1 之间。 设置 min，max 为 0 和 1， 此时刻度显示 [0,0.2,0.4,0.6,0.8,1] 。
这就导致极小数据会显示成一条树直的线。
### What is expected?
期望可以把很小坐标的点按比例画出来
### What is actually happening?
实际是极小值的点堆叠在一起，呈现一条树直的线

> 看了下你的 dataset，现在的 x 轴等于是类目型的，得先转成数字的。
这个没有太理解。 我在 series 中定义了 encode: {x: 1, y: 2} 然后将 x 轴指定成 value 类型。 这种方式实际上定义的 x 轴还是一个类目型的吗？
> 得先转成数字的
这个是说要设置 dimensions 吗。还是其他的操作啊
---
我现在尝试将 x 轴的 type 改成 log。 绘制出来的结果 x 轴的刻度是从 (1,10) 。 我将部分数据贴到你提供的 example 中，可以达到期望的效果。两边的不同的地方是：
- example 中 series 使用的 data 数组，我用的是 dataset 映射
剩下的是我的 series 中定义了如下的内容：
```json
{
datasetIndex: 0,
encode: {x: 1, y: 2},
lineStyle: {width: 2.5},
name: "xxxx",
showSymbol: false,
smooth: false,
symbolSize: 2,
type: "line"
}
```

对。
如果是 value 类型，应该都不需要 dataset 或者 data 了，最多指定一下最大最小值就行，类似 https://echarts.apache.org/examples/zh/editor.html?c=scatter-simple

不知道你说的没有效果是什么意思，是有 bug 还是仍然显示不好。https://echarts.apache.org/examples/zh/editor.html?c=line-log 这是一个 y 轴 log 的例子，你可以改成 x y 都是 log 轴的。

期望的效果：
能够将 `10E-8 ～ 10E-2` 这些**横坐标**值比较小的点能够显示出来。也就是**横坐标**的刻度可以设置成 `[0, 10E-8, 10E-6, 10E-4, 10E-2, 1]` 这样。 这样图看起来是一个折线形式而不是点都贴在横坐标 0 附近。

数据集里面前半段的数据基本落在 10E-9 ~ 10E-5 之间，加上 dataZoom 控件，看控件最小的刻度只能到 10E-6左右。
也尝试过将 X 轴改成 log 形式，也没办法实现期望的效果。
