Ling310 opened a new issue, #17292:
URL: https://github.com/apache/echarts/issues/17292
### What problem does this feature solve?
i need a new function same as api.currentSeriesIndices when pie chart legend active changed(eg. api.currentDataIndices) in custom chart.
I want to draw some extra graphic elements to pie chart, when legend active is changed,I wish my custom element colud show or hide at same time.
### What does the proposed API look like?
if I have three data, draw a pie chart, and this function I wish(api.currentDataIndices):
- do nothing, return [0, 1, 2]
- click first legend item make it unselect, return [1, 2]
