[Matplotlib-users] Displaying \frac{a}{b} in xlabel

[Nils W. <nw...@me...>]

Hi all,

How do I use \frac{a}{b} within labels ?

from pylab import *
from scipy import *
x = linspace(0,pi,20)
plot(x,sin(x))
title(r'\frac{\Theta}{2\pi}')
xlabel(r'\frac{\Theta}{2\pi}')  # The output is not o.k.
show()

Am I missing something or is it a bug ?
