matplotlib-devel Mailing List for matplotlib

Hi,
Does anyone know if there's a matplotlib event that fires when a
figure window is closed? I can't seem to find one.
If there's not one, any I shouldn't add one? I need to stop my
animation timers when the figure is closed.

You should probably avoid sending the same message to the list twice. You run the risk of only annoying the developers and not getting any real help.
The mplot3d axes code is in a major need of refactoring. There are very few developers who have worked on the mplot3d code. But at the same time, you will find that the code is much smaller, and more accessible than you might imagine. I found it very easy to fix some bugs in the bar3d function that I needed for my project.
So I suggest you look into fixing the bug yourself. It is pretty easy to submit patches to the development team.

Subject: [matplotlib-devel] Bug in mplot3d set_xlim3d, set_ylim3d, set_zlim3d
Hello matplotlib-devs,
I found what I think is a bug. If you run the following code, you'll see a simple figure with a graph at the position where the x-axis should be.
Unfortunately this is not the case, even if set_xlim3d(0,10) is set, so it should be at the edge of the plot.
The code:
import matplotlib as mpl
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
fig = plt.figure()
ax = Axes3D(fig)
x = range(11)
y = [0]*11
z = [0]*11
ax.plot(x, y, z, label='X-axis position')
ax.set_xlim3d(0,10)
ax.set_ylim3d(0,10)
ax.set_zlim3d(0,10)
ax.legend()
I attached the figure it produces.
You can also see, that from the edge to the 2 of one of the axis is a longer distance than from 2 to 4 on the same axis.
A way to fix it is highly appreaciated.

Understood.
I've attached the patch for the new triangular grid functionality.
I've altered it to use multiply-connected paths for filled contours
which has made the code a bit simpler overall.

Ian,
I went ahead and committed your refactoring. It seems to work fine. 
Contour.py was not pretty before the refactoring, and it is still not 
pretty, but I don't think it is much worse, if at all. I have a vague 
sense that ideally it would be factored somewhat differently, but I 
don't seem to have the time or vision to pursue it right now, and maybe 
if I did, I would still run into a dead end. So, let's proceed with 
what you have. If inspiration strikes later, I suspect it won't be too 
hard to modify both contour and tricontour accordingly.
