This is most likely because of the call to axes(). I can't remember for
sure, but it might be automatically clearing out the axes. Replace axes()
with subplot(131):
subplot(131).set_aspect('equal')
The subplot(131) call should recognize that that particular axes has already
been made and just simply retrieves it without modifying anything.
I hope this helps!
