Hello,
I think there is an unused parameter in matplotlibrc, the text.markup
which defaults to 'plain'. text.markup is not found in rcsetup.py.
Similarly, there is a keyword to ScalarFormatter, useMathText, that is
always set to its default, False, in ticker.py; no other function
accesses or uses that keyword. It seems that could be eliminated without
ill-effect.
I came across this while looking for a way to have the tick formatter
include a multiplication sign when writing very large numbers, instead
of using engineering notation such as 1e10. I would like to be able to
do this using the mathtext facilities native to matplotlib, and not have
to resort to usetex.
The following diff changes the tick formatter to work as I would like
it, but it also probably breaks something else because I have not tested
it at all. Please consider it as a starting point.
Paul
