[Matplotlib-users] savefig problems with matplotlib

[James L. <jwl...@gm...>]

I have intermittent problems with the savefig('foo.eps') command when I am
using my native LaTeX interpreter to produce eps files.  The really
frustrating thing is that it is intermittent.  Sometimes I can save a file
that looks fine and sometimes I can't.

My box is running Fedora Core 4 and kernel 2.6.14.

I have the following rpms:
python-2.4.1-2
ipython-0.6.15-1.fc4
python-tools-2.4.1-2
python-matplotlib-0.84-1.fc4
python-numeric-23.7-2

Fedora has an out of date ghostscript 7.07, so I installed
ghostscript-8.51from source into /usr/local, but not the fonts, since
they seemed
unnecessary.

As long as I don't use

rc('text', usetex=3DTrue)

I'm ok, but whenever I turn it on, it doesn't work consistently.

Here's some sample code to demonstrate the problem.  If I comment out the r=
c
line, it works fine.

#!/usr/bin/env python

from matplotlib import rc
from matplotlib.numerix import arange, cos, pi
from pylab import *

forces =3D [1, 2, 3, 4]
pofn =3D [.2, .09, .01, .005]

rc('text', usetex=3DTrue)
figure(1)
semilogy(forces,pofn,'k')
xlabel(r'$f_n =3D F_n/\langle F_n \rangle$')
ylabel(r'$P(f_n)$')
axis([0,5,.001,1])

savefig('mtest1.eps')

However, if I run it as is, then I get the following:

[jwlandry@merrimac hopper]$ ./mat-test.py --verbose-helpful

When it doesn't work, a dialog box opens with this message

Save figure failure:

Help!
