You can accomplish it by:
ax.texts.remove(arrow)
I'd still like to know why this exception gets raised:
NotImplementedError Traceback (most recent call last)
/home/rmay/<ipython console> in <module>()
/home/rmay/.local/lib/python2.6/site-packages/matplotlib/artist.pyc in
remove(self)
123 self._remove_method(self)
124 else:
--> 125 raise NotImplementedError('cannot remove artist')
126 # TODO: the fix for the collections relim problem is to move the
127 # limits calculation into the artist itself, including
the property
NotImplementedError: cannot remove artist
JJ, thoughts?
