What problem does this feature solve?
Hi.
First of all, thank you for distributing such a great chart component.
echrats is so awesome.
I have a question.
Is there a function to select the corresponding data by selecting the chart area, axis area, legend item, etc. as shown in the figure below??


If so, how can I access it?
If not, how can I add it?
Please give me a hint. Thank you.
What does the proposed API look like?
