Hello! Is there any news about this issue? Legend for Sunburst still not working.

[mgsod]

到现在依旧无法展示legend.

尝试过手动设置legend中的data与series中的每项name一致，可以显示legend。

但是点击legend切换就会出现一下问题：

• 第一次点击可以隐藏对应的series的扇区

• 再次点击legen想显示series时却无法显示

Hi, We have been using echarts and happy. Well done! That said, why this issue is not fixed even after 4 yrs ? It is not so much an enhancement but basic missing feature/function. Legend is a basic requirement for any chart. Plz fix ASAP. Thanks, Tim

居然4年前就有这个问题…… 我通关其他方式解决了： 增加一个饼图，然后监听legendselectchanged事件，再更新图表
