Dear All,
I think the solution to my problem must be a one-liner, but I have
been unsuccessful.
I am trying to use latex formulas (nothing dramatically complicated)
inside a figure.
I suppose everything is working correctly on my system.
I tried running the example at:
http://www.scipy.org/Cookbook/Matplotlib/UsingTex
and it works fine.
But now have a look at this:
#! /usr/bin/env python
import scipy as s
import numpy as n
import pylab as p
x=s.linspace(0.,(2.*s.pi),100)
y=s.sin(x)
z=s.exp(-x)
#Now I create my figure
fig = p.figure()
axes = fig.gca()
axes.plot(x,y, "bo",label=(r"$sin(\tau)$"))
axes.plot(x,z,'--r',label=(r"$\rm{decay}exp(\tau) $"),linewidth=2.)
p.xlabel('This is $\tau$')
p.ylabel('$N_\infty(\tau)$')
axes.legend()
p.title('My test functions')
p.grid(True)
p.savefig("simple_test.pdf")
p.clf()
The point of the example figure is to try mixing latex formulas and text.
Obviously, the result is not satisfactory. If I use \sin for instance,
then I get an error message as that is not recognized.
I think the fix to this must be rather simple for someone
knowledgeable, but so far my attempts to get some decent mixed
latex/text output have been unsuccessful.
Can anyone help me with this simple example code?
Many thanks
Lorenzo
