It looks like calling ax.relim() is the preferred way of setting limits
after deleting artists. Unfortunately this method does only consider
patches and lines. I added some lines in axes.py to support images to
(the patch against the current svn-version is appended).
If this is not the correct place for submitting patches please tell me
where I should put it instead.
Thanks and best regards
