matplotlib-users Mailing List for matplotlib

I get a mysterious problem when I try to upgrade from 87.2 to 87.3.
At first it complained of a bad configuration file. Once that was 
corrected, though, matplotlib still crashes Python as soon as "import 
pylab" or "import matplotlib" is called. No message of any kind is passed.
The Windows error report says the exception was in multiarray.pyd. I 
can reinstall 87.2 and everything is fine. Any idea what the problem 
might be?
Thanks!

you could try using the matplotlib SVG backend. Skencil can import SVG,
although skencil can only use the old X-style font system, so my plots
(which use Bitstream Vera fonts by default) didn't look too nice. You
could fix this by setting more compatible fonts in the matplotlibrc
presumably.
Alternatively, you could try Inkscape in place of Skencil for editing
SVG files. Inkscape can print to PS/EPS/AI for inclusion in a LateX or
skencil document (.ai). It can optionaly convert text to paths, avoiding
the font problems.

 Hi all,
I tried to reproduce the Contour3D plot 
http://www.scipy.org/Cookbook/Matplotlib/mplot3D.
from numpy import *
import pylab as p
import mpl3d.mplot3d as p3
p.matplotlib.__version__
# in mplt3D change:
# levels, colls = self.contour(X, Y, Z, 20)
# to:
# C = self.contour(X, Y, Z, *args, **kwargs)
# levels, colls = (C.levels, C.collections)
delta = 0.025
x = arange(-3.0, 3.0, delta)
y = arange(-2.0, 2.0, delta)
X, Y = p.meshgrid(x, y)
Z1 = p.bivariate_normal(X, Y, 1.0, 1.0, 0.0, 0.0)
Z2 = p.bivariate_normal(X, Y, 1.5, 0.5, 1, 1)
# difference of Gaussians
Z = 10.0 * (Z2 - Z1)
fig=p.figure()
ax = p3.Axes3D(fig)
ax.contour3D(X,Y,Z)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
fig.add_axes(ax)
p.show()
