matplotlib also ships with some AFM fonts which are put in a system
dir by the setup.py script.  They reside in the fonts/afm dir of the
matplotlib src distribution.  

I'm curious, postscript is usually not such a great format for serving
web images.  Do you plan on using a PS->PNG converter on the server
side?  By the way, if you are on linux, the GD setup is fairly
painless if you follow the steps in the "Quick install guide for GD
output" on http://matplotlib.sourceforge.net/backends.html.  I need to
generate some server side graphics myself -- that was one of my main
incentives for porting to GD.

Good luck -- if you have a publicly accessible web page serving up
matplotlib graphics in the future, let me know as I'd be interested in
checking it out.

First of all, one of the easiest graph package yet fill with tons of
capability and future potential.

Now my issue:

1. I am trying to integrate matplot with quixote. It fails because of gtk (I 
think). How can I use matplot  without gui requirement.

2. I am trying to save an image without showing it. Here is small program

**************************************************************
from matplotlib.matlab import *
plot([1,2,3])
savefig('test.png')
#show()

***************************************************************

This does not create test.png file, but if I uncomment last line, it create
test.png file. How can I create a test.png file without showing it?

Commented out line 43 in _matlab_helpers fix my issue. Is it because I don't 
have any window to destroy?


Here is small example (which creates problem without commenting line 43)

from matplotlib import use
use('GD')
from matplotlib.matlab import *
bar([0,1], [0,2])
savefig('test.png', dpi=100)
close('all')

bar([0,1], [1,1])
savefig('test1.png', dpi=100)
close('all')



********************New destroy function in _matlab_helpers (Need a fix if you 
have window to destroy 
*******************

    def destroy(num):
        if not GcfBase.has_fignum(num): return
        figwin = GcfBase.figs[num]

        oldQue = GcfBase._activeQue[:]
        GcfBase._activeQue = []
        for f in oldQue:
            if f != figwin: GcfBase._activeQue.append(f)

        del GcfBase.figs[num]
        #figwin.window.destroy()
    destroy = staticmethod(destroy)

Just FYI.

It looks like you are running in an environment where HOME is not set.
The TTFQuery file _scriptregistry.py first checks for the HOME
environment variable and tries to put the font cache there.  If it
fails, it falls back on a python dir (which works well for linux and
win32 respectively).  Also, make sure you are using version 0.2.6 of
TTFQuery.

So either 1) set HOME to point to where you want to font cache to go,
or 2) Edit _scriptregistry.py and manually set the registryFile
variable at the top of that script.

I understand.  If you have a publicly viewable screenshot that you can
share for the screenshot page, let me know.  Otherwise, just pass on
what you learn about the mechanics of getting it up and running.
