分级填色地图的VisualMap，如何使用categories属性，实现自定义颜色分类？

[minren118]

Version

5.0.0

Steps to reproduce

VisualMap的官方示例中，是以散点图为例，散点图的series最后一列是categories匹配的列，但在Map系列的填色地图里，尝试把Data属性加入额外的信息时，最终做图渲染颜色失败.

目前测试结果，Map系列的data属性，只能是name、value结象数组。

我如何才能把VisualMap的categories所映射的列传入到Map系列地图中？

What is expected?

可以实现Map系列地图的VisualMap中的categories属性绑定，实现自定义颜色填充。

What is actually happening?

当前不能实现Map系列地图的VisualMap中的categories属性绑定。

**TITLE** How to use the categories attribute in VisualMap of graded color map to realize custom color classification? **BODY** ### Version 5.0.0 ### Steps to reproduce In the official example of VisualMap, the scatter chart is used as an example. The last column of the series of the scatter chart is the column matched by categories, but in the coloring map of the Map series, when trying to add the Data attribute to the additional information, the final drawing is done.Failed to render color.  According to the current test results, the data attribute of the Map series can only be an array of name and value nodes.  How can I transfer the columns mapped by the categories of VisualMap to the Map series map? ### What is expected? The categories property binding in VisualMap of Map series maps can be realized, and custom color filling can be realized. ### What is actually happening? Currently, it is not possible to bind the categories property in the VisualMap of the Map series map.

        inRange: {
            color: ['red', 'green', 'blue'],
        },
    },

   series: [
        {
            type: 'map',
            map: 'china',
            data: [
                { name: 'region0', value: [1, 'aa'] },
                { name: 'region1', value: [2, 'bb'] },
                { name: 'region2', value: [3, 'cc'] },
            ],
