can Pie response to user-interaction like that in the attached pic.

I want to drag the edge (tag) of the pie, in order to change the percentage of each section.

Thanks,

Yan

At this time this is supported only for bar and line charts. Our developer will try to implement it for pie charts in the next few days.

Thank you, Stoyan.
I tried the bar chart. It works fine.

I came across another question:
I couldn't find any event related to when/after "Mouse Drag" happens.

I want to make some calculations with the new values right after I drag the bar.
Thank you.

I found this event MouseCaptureChanged, which works for my purpose.

This version adds AllowEdit property to PieChart:
https://mindfusion.eu/_beta/edit_chart.zip

When it is enabled, you can edit data values by dragging the radius line between two segments. The control will also raise DataChanged event when the user resizes segments.

I hope that helps,
Stoyan
