Re: [Matplotlib-users] finding the bounding box of an arbitrary artist

[Daniel H. <dh...@gm...>]

No, I didn't... I believe that in this specific case, I just manually drew
a decently sized box around the axis spine and implemented my own contains
method to match.

It would be nice for every artist to be consistent in this area though.
Maybe a MEP is in order to make every artist have a consistent interface as
defined by the base class?
