[GitHub] [echarts] magicdict opened a new issue #14964: 能否修改一下类型定义文件
magicdict opened a new issue #14964:
URL: https://github.com/apache/echarts/issues/14964
### Version
5.1.1
### Steps to reproduce
我现在想开发一个能够灵活生成Option的第三方库，所以使用了@types/echarts这个类型定义库。
大部分类型定义都很好，确实不需要我再次定义类型了。但是，有一些功能可以考虑加入。
例如，其实echarts是支持一个color属性为一个fn(parm)=>string的，这个在bar类型，不同bar显示不同颜色的时候非常有用。
但是在@types/echarts的itemStyle里面，EChartOption.Color的定义如下
type Color = string | LinearGradient | RadialGradient | Texture;
这样的话，我不知道怎么将一个fn赋予Color。
getColor(params: any):string {
//定义一个颜色集合
var colorList = ChartColor.colorlist_7_Baidu;
//对每个bar显示一种颜色
return colorList[params.dataIndex];
}
能不能将这个定义稍微修改一下，能够让二次开发者实现更多的功能呢。
### What is expected?
Color无法使用FN
### What is actually happening?
Color无法使用FN

在定义里面，有些属性确实是允许Function的，例如emphasis的formatter?: Function | string;
这里的差异到底是怎么回事？能不能吧支持function的属性都补全呢？
