matplotlib-devel Mailing List for matplotlib

Thanks Eric; this is what I was looking for, and it's a shame that there
seems to be no way to accomplish this without cherrypicking a commit or
range of commits. It seems that since v1.1.1 and master can be traced back
to some common ancestry, that git should be able to rewind and replay the
changes so that cherrypicking or reimplementing wouldn't be necessary.
 I've archived this email, though, so that I can use it at the appropriate
time.
For the immediate need, I was going to add the keyword 'bbox_size' to
Annotations, so that the user can optionally specify the box size around an
annotation...also was going to add additional boxstyles for Annotations, so
that one could use a circle, ellipse, or any other type of patch to enclose
the annotation. This would be useful for flowcharting and any other use
where the user wants a "patch with text inside".
As it stands, though I can only get 95% of this done...I can't seem to get
the placement of the patch correct when the text is rotated, unless
ha='center' and va='center', or if rotation_mode='anchor'. So since I
would cause a regression here, I guess it's off the table.
