Save pdf with plot_surface

This may be known, but the following modified example from http://matplotlib.org/mpl_toolkits/mplot3d/tutorial.html fails with a TypeError at matplotlib/backends/backend_pdf.pyc in draw_path_collection. Is it possible to save pdf files with surface plots?

from mpl_toolkits.mplot3d import Axes3D

from matplotlib import cm

from matplotlib.ticker import LinearLocator, FormatStrFormatter

import matplotlib.pyplot as plt

import numpy as np

fig = plt.figure()

ax = fig.gca(projection=‘3d’)

X = np.arange(-5, 5, 0.25)

Y = np.arange(-5, 5, 0.25)

X, Y = np.meshgrid(X, Y)

R = np.sqrt(X2 + Y2)

Z = np.sin®

surf = ax.plot_surface(X, Y, Z, rstride=1, cstride=1, cmap=cm.coolwarm,

linewidth=0, antialiased=False)

ax.set_zlim(-1.01, 1.01)

ax.zaxis.set_major_locator(LinearLocator(10))

ax.zaxis.set_major_formatter(FormatStrFormatter(’%.02f’))

fig.colorbar(surf, shrink=0.5, aspect=5)

fig.savefig(‘test.pdf’)

plt.show()

I was able to fix this by uninstalling the matplotlib from homebrew and installing with pip.

Just curious -- where is the formula for matplotlib in homebrew? I can't find it. I thought I would look into why that was failing -- it may just be simply that it's an old version of matplotlib and this bug is now fixed in the latest release.
