@GitHubLionel - Will you be able to fix this? I've suggested a fix; just track bounding boxes for each plot legend in a vector or list, then iterate over the vector and check "IsInside"... Thanks!

GitHubLionel commented 3 months ago

I don't think it is so easy. Legend is drawn in a bitmap for speed. So for example when you resize the window, just the bitmap is redrawn, but the coordinates of each plot legend have changed.

DRNadler commented 3 months ago

Resize is infrequent so speed not so important. Anyway, suggested correction will result in:

much shorter code (if coded correctly), and
same performance (or close enough you cannot measure the difference)
