I just refactored some custom code to make use of
axes_grid1.ImageGrid, and I think I've come across a bug (see below).
It looks like the tick labelsize doesn't get passed properly to the
parasite axes.
I'm using Python2.6, matplotlib-1.0.0 release, and the Qt4Agg backend.
Also, I noticed that the Grid.__init__ super-class constructor isn't
called in the ImageGrid.__init__ constructor; should it be?
By way of feature request, I'd prefer to be able to specify share_x
and share_y in the constructor, but that's not available in ImageGrid,
only in Grid.
If there's agreement that this is bug, I'll file it on the sourceforge
tracker. Is this fixed in SVN, or does anyone have workaround, e.g.,
some way to convert 'x-small' to the correct integer size, or a
different method to call?
Thanks,
Justin
