It looks to me like the code was trying to delete all axes but one from
the figure. This probably worked when Figure.axes was a plain list, but
for quite some time it has been a read-only list generated from an
AxesStack instance.
The code will need rewriting based on an understanding of what it is
trying to do, and how mpl works now. There is no shortcut. For this
particular problem, you might be able to do something like this:
fig = self.ax.get_figure()
axlist = fig.axes
for ax in axlist:
if not ax == self.ax:
fig.delaxes(ax)
