Well, as JJ pointed out recently, there is
matplotlib.ticker.LogFormatterMathtext as a much better template to
use ... Well, and even for scalar formatters, there is
matplotlib.ticker.ScalarFormatter(useMathText = True) ... Shame on me!
But it seems there is a small drawback: For non-rc-usetex mode,
\mathdefault{} is used, making the math typeset in the normal,
outside-math font (according to
http://matplotlib.sourceforge.net/users/mathtext.html?highlight=mathdefault#fonts).
What is the advantage of using
matplotlib.ticker.ScalarFormatter(useMathText = True) then, when it's
typeset in outside-math font anyway?
