Yes, that looks like the problem, but not the solution. self.contour
is the return value of ax.contourf, which is a ContourSet.
Unfortunately, the matplotlib.contour documentation has not yet been
ported to the sphinx/rest doc system (Eric, hint, hint). But you can
read the docs in the source of matplotlib/contour.py or in the python
shell with help matplotlib.countour.ContourSet. To do what it looks
like you are trying to do, if you want to force a draw on the contour
artists (which are matplotlib.collection.Collection instances), you
would do
self.contour = ax.contourf(...)
for col in self.contour.collections:
ax.draw_artist(col)
