Re: [Matplotlib-users] Button and Mouse event

[Benjamin R. <ben...@ou...>]

I am sorry, I am not sure that I understand what you are trying to do. Why
do you want the same action to happen whenever you click the mouse button
(anywhere in the figure), and whenever you click the mouse button (when you
are over the button)? The two areas overlap, so it would always trigger the
action twice when clicking on the button.

Why are you attaching the callback to mouse button clicking when it is
already attached to the Button?

P.S. - please keep the coverstation on-list.
