I'm making a small visualization application based on matplotlib which is in turn embedded in gtk2 using pygtk. The code goes like this:
fig = matplotlib.figure()
ax = fig.add_subplot(111)
im = ax.imshow(A)
canvas = FigureCanvas(fig)
and it works fine. However, after an user action I need to update the image, and so I do a
but the image remains unchanged, and will only update if I somehow move it using the toolbar. I googled a bit and found that perhaps fig.draw(renderer) would work, but I have no idea as how to get a reference to the renderer. Any ideas?
