matplotlib-users Mailing List for matplotlib

The best I can guess is that this is a bad binary build. Is SUSE repository
tracking the development branch of matplotlib or the stable release? What
version of matplotlib does zypper say it installed?

For the record, another way to handle this situation is to use subplot 
parameters to leave adequate room on the right, then use the 
Axes.add_axes() method to make an Axes for the colorbar, and provide it 
as a cax kwarg.

Hi Ben,
Thanks for those tips. I ended up giving a list of axes to the ax argument
of colorbar as you suggested. That took care of the misalignment of the
top plots and bottom plots but then the colorbar extended the full vertical
height of both rows of axes. Fiddling with the shrink and anchor parameter
values then got me what I wanted. I'm sure that axis_grid1 could work as
well, but my situation is sufficiently complicated that I don't want to
spend the time fiddling with it at this point.
Regards,
Jon

OK, thanks for your answer. I've opened a issue in Matplotlib's github.
