memory "leak" caused by canvas.draw()

Community matplotlib-users

I explored the memory leak in my strip chart widget some more and found
that it is caused by calling canvas.draw(), where canvas is:

figure = matplotlib.figure.Figure(figsize=(8, 2), frameon=True)
canvas = FigureCanvasTkAgg(figure, self)

canvas.show() exhibits exactly the same problem.

So...what is the right way to redraw a plot after its X axes have been
changed?

draw() *is* the right way. It should definitely not be leaking.
Hopefully someone familiar with those kinds of problems can take a
look. (I just don't have the time right now.)
