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.
