Hi Charlie,

Jenny here. I'm trying to make an executable of my python program that uses
MatPlotLib. I tried your example below and I got this kind of error when I
ran the exe. I'm using python 2.3.3, MatPlotLib 0.87.3 and py2exe 0.6.5. I
really need to use the MatPlotLib don't know what to do.

Thanks,
Jenny

It's a bug. Edin said he would work on it.

The demo doesn't work out of the box. You need to install download the 
freefont fonts into your mpl-data directory, and then add the following 
before the pylab import in mathtext2_demo.py:

from matplotlib import rcParams
rcParams['mathtext2'] = True
rcParams['mathtext.rm'] = 'FreeSerif.ttf'
rcParams['mathtext.it'] = 'FreeSerifItalic.ttf'
rcParams['mathtext.tt'] = 'FreeMono.ttf'
rcParams['mathtext.mit'] = 'FreeSerifItalic.ttf'
rcParams['mathtext.cal'] = 'FreeSansOblique.ttf'
rcParams['mathtext.nonascii'] = 'FreeSerif.ttf'

Hey guys I am creating an application that deals with a few graphs, but it
does other things also.

What I would like to do is to have a wx.Panel that takes some input from
the user, and then when I get the information I plot some data.  The user
picks a start and finish point on the graph and then I apply a cubic
integration function.  It then goes to antoher function that is graphed
the user picks max and mins on that data, then the two graphs are compared
to each other.

I have the implimentation done up to creating the graph, and allowing the
user to work with it.  The problem that I am having is that there are
parts in between that i need to stop showing the graph and ask for more
user input, via text boxes.

Does anyone know an easy way to go about doing this?  I am trying to use
wxmpl because it seemed to be easy but it does not seem to have the
complete functionality that I would like to use.

Thanks,
-Kenny

	Hello, 

I saw that mathtext2 was include in the svn, I try to test it but even the 
demo is not working with the error message:



ValueError: unrecognized symbol "\frac3"
WARNING: Failure executing file: <mathtext2_demo.py>
