wxPython includes a wxversion module that lets one select whihc version
of wxPython you want run, if more than one is installed. It might be
nice if those calls could get put into MPL somewhere, so that when MPL
is built against a given version, that version will be run

That all being said, it would be nice to establish a standard convention

I get a repeatable bus error when trying to plot more than
one histogram of simulated data. The first plot is generated
without error, but invariably a second plot crashes:
In [4]: x = random.negative_binomial(2, 0.25, 1000)
In [5]: from pylab import *
In [6]: hist(x)
Out[6]:

For some reason, builds from SVN dont install either pytz
or dateutil (at least not in the right place). Importing pylab
from these builds results in an import error.
How can I build these so as to convince these modules to
install correctly?
Thanks.

Actually, I did manage to fix this by specifying a zorder of 10 for the
plots and a zorder of
'datetime.datetime' and
'float'
What am I doing wrong?
Also, how do I go about adding a second set of bars? (ie: from data2)?

So, basically make the x axis time instead of numbers.
