[Matplotlib-users] Fwd: Problem with adding an artist from one axes instance to another

When you add an artist to the Axes, it checks to see if you have set a
transformation.  If you haven't, it will set the default axes
transformation.  If you have, it leaves the transformation unchanged.
This is why you are seeing the problems you see.

Before adding them to the second axes, you need to reset the
transformation for each line, text, etc....


for artist in ax.get_child_artists():
   artist.set_transform(ax2.transData)
   if isinstance(artist, Line2D):
       ax2.add_line(artist)
   elif ....

should work....
