What is wrong with your output? It looks fine to me. Maybe there is an issue
with your ps viewer. Try using the agg backend, and saving a png to compare
the results.
Also, a couple comments:
Any of your strings that have backslashes need to be raw strings:
'$\sin(x)$' should be r'$\sin(x)$'.
You should do this:
import matplotlib as mpl
params = {'backend': 'ps',
'axes.labelsize': 10,
'text.fontsize': 10,
'xtick.labelsize': 8,
'ytick.labelsize': 8,
'text.usetex': True,
'figure.figsize': fig_size}
mpl.rcParams.update(params)
before you do this:
import pylab
