PROBLEM
The mouse interactions are off by some offset. The issue is that the mouse position is relative to the viewport and not the chart element itself. This is partly because the
mousemove
andmouseup
are listening from thewindow
and not the chartelement
to provide better drag and drop flexibility.SOLUTION
Adjust mouse event positions to take element position (via
getBoundingClientRect
) into account.
