I've never seen a drag-n-drop system that works with the charts. Most of
them clone the elements and recreate them in the new location. Cloning
doesn't preserve event handlers, though, so you'd have to find a
drag-n-drop system that moves the element without cloning it (which I'm not
entirely certain is even possible).
If you redraw the chart on completion of the drag-n-drop, though, all
interactivity will be restored.
