Hello,
I am getting an error when I try to use any TeX formatting in plot
labels. There is an example below. I don't know if its relevant, but
I can only use the "latex" command in my OSX terminal. If I try
"latex sample.tex" in an x11 window, x11 claims no knowledge of latex.
I have had to install two libraries and hunt down my kpathsea library,
and this still isn't working. Is there any easier way to achieve text
and math together in a label, such as "Text $\pi$" ? Thanks,
Adrian
In [1]: matplotlib.rc('text', usetex=True)
In [2]: plot(arange(3), arange(3));xlabel('Text')
sh: line 1: latex: command not found
