I am making some plots with matplotlib, and I've come across a problem with the TeX rendering. It seems that the mathtext x-height is is a bit smaller than the normal Bitstream Vera Sans. See the following example:
x = linspace(0, 30, 300);
y = 0.5*rand(300)+20/(numpy.power(x-15, 2)+4);
xlabel(r'$\omega$ (rad$\cdot$Hz)');
ylabel(r'Intensity$^2$');
title(r'Why is $mathtext$ so much smaller than normal text?');
As you can see, it's particularly noticeable with greek letters and numbers. Ideally, I'd be able to define some scaling factor that would just make the math text a bit bigger at each font size. Is there any way to do this simply? I do not want to simply use Computer Modern everywhere. I also do not want to compile a new Tex math font, if that's even possible.
One solution that I would be on board with is using sans-serif fonts for the greek letters and numerals, but for whatever reason, matplotlib ignores formatting on those:
title('Why does $mat\mathsf{plot}lib$ ignore formatting for $\mathsf{2}$ ($\mathsf{two}), $\mathbf{2}$ ($\mathbf{two}) and $\mathsf{\omega}$?')
I assume it's something to do with the nature of how these things are typeset, but is there any way to fix it?
