[Matplotlib-users] Tex-style factorial ! in legend

[andreasl <and...@la...>]

Hello,

When I use something along the lines of

legend( (r'$0.5^x/x!$', r'$1^x/x!$') )

for some reason omegas are drawn instead of the ! sign. I can't find an 
alternative here <http://matplotlib.org/users/mathtext.html> nor 
elsewhere. Any ideas?

Many thanks,

Andreas

Looks fine to me. Do you have rcParams['text.usetex']=True?

Thanks Damon. No, I was using matplotlib's own mathtex 
<http://matplotlib.org/users/mathtext.html> rather than direct LaTeX 
support <http://matplotlib.org/users/usetex.html>. If I do set usetex to 
True, trying to plot anything results in errors, the output including:


! LaTeX Error: File `type1cm.sty' not found.

This issue is mentioned 
<http://matplotlib.org/users/usetex.html#possible-hangups> on the 
matplotlib webpage (I am using Ubuntu-derived Mint). I'm not keen to 
install type1cm as part of Mint's space-chomping 485MB 
texlive-latex-extra package. May figure out how to install it 
individually; if anyone has experience with this, please shout. Cheers.

This is working for me, even with text.usetex set to "False".  What 
version of matplotlib are you using?  Do you have anything set in your 
matplotlibrc file?
