Re: [Matplotlib-users] Save pdf with plot_surface

2013-04-21 Thread Michael Droettboom 
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.

[Matplotlib-users] Save pdf with plot_surface

This may be known, but the following modified example from

TypeError at matplotlib/backends/backend_pdf.pyc in draw_path_collection.
 Is it possible to save pdf files with surface plots?

fig = plt.figure()
ax = fig.gca(projection='3d')

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