hi all,
two quick questions about labels. first, is there a way to make
subscripts/superscripts *without* using TeX in labels? For example, I
use helvetica in all my labels and I want to plot something like:
plt.xlabel("log10") where "10" is a subscript of "log", but without
doing: plt.xlabel(r"$\log_{10}$"), since that will use LaTeX fonts
instead of my helvetica font.
second question, when using TeX, I tried the following TeX command in labels:
plt.annotate(r"\frac{\sigma}{\sqrt{\mu}}", ....) but it complains that
"not all arguments converted during string formatting" -- but it seems
like correct TeX to me. if I try r"\frac{1}{2}" then it works, but
using \sigma and \sqrt inside breaks it.. any idea how to fix this?
thanks.

Unicode strings might be the answer for this. Though needs someone’s confirmation.

Have you forgotten “$” ? The following works correctly in my system.
plt.xlabel(r"\frac{\sigma}{\sqrt{\mu}}")

See the mathtext options in matplotlibrc.template. It looks like what you need is
matplotlib.rc('mathtext', fontset='stixsans')
maybe with the additional kwarg, default='regular', if you don't want italics.
All this is with text.usetex=False (the default).

This is working for me with usetex=False or True but including dollar signs to signal the use of mathtext (or TeX) parsing.
