Re: [Matplotlib-users] unable to point pick 2nd axis after upgrade to mpl 1.0

[Jae-Joon L. <lee...@gm...>]

As far as I understand, all the events in matplotlib are associated
with a single Axes instance (or None). For overlapping multiple axes,
the axes with highest zorder is picked up. And a "pick
 event only works for artists in the associated axes.
While this simple approach is okay at least to me, I want to hear from
other developers.

For the example above, a workaround is to move the line to the axes of
higher zorder.

line.remove()
ax2.add_line(line)
