Tex-style factorial ! in legend

Thanks Mike. Interesting that it works for you with mathtext only.

I am in some confusion about the matplotlib version I'm using. Synaptic (package manager) says that for matplotlib I have 0.99.1.2-3ubuntu1installed. Asking for help(matplotlib) in python gives

FILE
/usr/local/lib/python2.6/dist-packages/matplotlib-1.0.1-py2.6-linux-i686.egg/matplotlib/__init__.py

I did not change anything manually in matplotlibrc, of which I seem to have three versions:

/etc/matplotlibrc
/usr/local/lib/python2.6/dist-packages/matplotlib/mpl-data/matplotlibrc
/usr/local/lib/python2.6/dist-packages/matplotlib-1.0.1-py2.6-linux-i686.egg/matplotlib/mpl-data/matplotlibrc

The first one has backend: TkAgg whereas the other two have backend: GTKAgg. Everything else is commented out. I usually work from within the Spyder IDE, where the backend is set (via Preferences) to Qt4Agg. I get the faulty behaviour (omega instead of !) both from within Spyder and from within a console ipython session (where presumably either TkAgg or GTKAgg is used). Setting the backend to either TkAgg or GTKAgg in Spyder results in no plot at all.

This is working for me, even with text.usetex set to "False". What
version of matplotlib are you using? Do you have anything set in your
matplotlibrc file?

Hello,

When I use something along the lines of

legend( (r'$0.5^x/x!$', r'$1^x/x!$') )

for some reason omegas are drawn instead of the ! sign. I can't find
an alternative here <http://matplotlib.org/users/mathtext.html> nor
elsewhere. Any ideas?

Many thanks,

Andreas

It looks like you have both a package manager installed and a locally installed copy then, and the one that is being imported is the local copy (1.0.1).

I believe this bug existed then, but was fixed in 1.1. You may want to upgrade to 1.1.1 or the new 1.2.0rc2 if you want to live on the edge.
