I’m using matplotlib 0.9.12 from ubuntu hardy 8.04.
To take advantage of the LaTeX handling capability in matplotlib,
I’ve added next two lines in /etc/matplotlib
text.usetex : True
text.latex.preamble : \usepackage{amsmath}
Then, I tried next test code.
from pylab import *
x = []; y = []
figure(figsize=(2,2))
plot(x,y,label=r’$\theta=$0.0deg’); axis([0,1,0,1]); legend()
text(0.5, 0.5, r’\begin{align*}x&=\alpha\y&=\beta\end{align*}’)
savefig(‘test.eps’)
However, I’ve got the following error message without a resulting eps file.
···

How can I save a plot with a LaTeX environment in eps format?
