Current Behavior
地图数据是静安工业园区和雷公尖乡，这两个区域分别都包含了两个子区域。因为子区域之间并不接壤，区域名称只显示了一个，但显示在哪个子区域上并不固定
Expected Behavior
期望多个子区域都能显示区域名，或者区域名固定显示在第一个子区域上

TITLE
When map3d renders geojosn data, when an area contains multiple sub-areas, the map name display cannot determine which sub-area it is on.
![echarts-bot[bot] avatar](https://avatars.githubusercontent.com/in/20872?v=4 "Published by a pub.dev verified publisher"){kind=small}
the map name display cannot determine which sub-area it is on
I think the name goes to the first sub-area. And that is normal. It would be worse to have the name in the middle, completely disconnected from both areas. What one can do is separate the sub-areas geometries and name them individually.

the map name display cannot determine which sub-area it is on
I think the name goes to the first sub-area. And that is normal. It would be worse to have the name in the middle, completely disconnected from both areas. What one can do is separate the sub-areas geometries and name them individually.
Demo Code 📌
起初我们用的方式就是这个，但是现在需求是同一区域的子域名要放在一起，而且geojson数据是支持这么做的 问题是区域名称显示的不一定是第一个，给的例子中，静安工业园区显示的是在数组第一块区域中，雷公尖乡显示的是在数组第二块区域中。我现在数据有限，只能确定名称不是固定显示在第一个区域，期望是固定显示第一个或者有规律性
the name is not always displayed in the first area. I hope it is always displayed first
I agree, Now lets imagine the name gets displayed always on the first sub-area. Would you leave the second without a name?

最好是和第一块显示一样的名字，选中的时候同一区域下所有子区域会同时高亮，可能让人无法理解
