Thanks Ken. I think I did this before a year or so ago, I was just
thinking there was an easier way.
I guess I am a little stuck. I am hesitant to upgrade to wxPython 2.8
because wxGlade isn't compatible with it yet. I just went to
wxPython.org and their sourceforge page doesn't have 2.6 source
Thanks for the help Ken. I think I got it. The source install of
libwkgtk2.6 doesn't seem to be enough (I still get the message about
accelerator needing the headers).
I have downloaded the 2.6 source tarball (thanks for finding it). I
copied *.h from the wxPython-src-2.6.3.3/wxPython/include/w
ed on it.
Am I making any sense? Am I going about this revision in a good way?

It is probably overkill, but I use Latex for this. You can fairly
easily have Python generate a text file that is the Latex input,
including captions for each figure. And then call latex using
os.system.
This might get you a psmerge for windows:
http://gnuwin32.sourceforge.net/packages/psutils.h
I think I was the one who asked a similar question a while back. Here
is a link to John's response:

I followed his advice and created my own formatter:
from matplotlib.ticker import LogFormatterMathtext
class MyFormatter(LogForm
I would need to create a timeline for a Latex document (eps output).
There may be other tools besides Matplotlib and I am open to
suggestions. But I were going to use mpl, what would it take to do
something along these lines:

You can set matplotlib up to use LaTeX, but it can be a little bit of
work to get it going. The results are quite beautiful though.
set usetex = 1 in yout matplotlibrc file to try it out. It depends on

You have two options. savefig does have a dpi option that will
essentially set the figure size for the saved file:
savefig('myfile.png',dpi=300)
play with dpi until you get a figure size you like.
The other way to set the figure size is to specify it when you create
the figure:
figure(1,(10,8))
