matplotlib-users Mailing List for matplotlib

hello,

I'm trying to create a distro with py2exe, including MatPlotLib.
After finally resolving the matplotlib datapath problem,
I bumped into a new problem concerning backends.

I'm using MatPlotLib 0.91.2
I only need the wx-Backend.

In Py2exe I tried to exclude as many backends as possible,
but the excludes seems to have no effect.
      'excludes' : [
         '_gtkagg', '_tkagg', '_agg2', '_cairo', '_cocoaagg',
         '_fltkagg', '_gtk', '_gtkcairo',
         'backend_qt', 'backend_qt4', 'backend_qt4agg',
         'backend_qtagg',
         'backend_cairo', 'backend_cocoaagg',
         'Tkconstants', 'Tkinter', 'tcl',
         "_imagingtk", "PIL._imagingtk", "ImageTk", "PIL.ImageTk", "FixTk"
          ],

The creating of the distro seems to work,
but the distro won't run,
because of some problems with tk-backends, (which I don't need or even 
want).

The problem might be caused by a crashed installation of tk in the past.
And might also be amplified by the fact that I use
   from pylab import *

Now I guess I can effectively remove the unnecessary backends,
by removing the following lines from \backends\__init__.py

interactive_bk = ['GTK', 'GTKAgg', 'GTKCairo', 'FltkAgg', 'QtAgg', 'Qt4Agg',
                  'TkAgg', 'WX', 'WXAgg', 'CocoaAgg']
non_interactive_bk = ['Agg2', 'Agg', 'Cairo', 'EMF', 'GDK',
                      'Pdf', 'PS', 'SVG', 'Template']

I don't know if this solves the problem (haven't tried it yet),
but I certainly thinks this is not the proper way to go.

Any solution / suggestion would be very welcome (while MatPlotLib is 
quit essential in my distro)

thanks,
Stef Mientki

Well, you have to ask for a legend, but everything else 
default looks good to me.  What is an example where you do 
not like the default behavior?

Are you trying to make a bunch of figures look alike?

There seems to be some deep confusion here.  You say you are using the
default GTKAgg, but then try "reload" (suggesting an interactive
session) and then call matplotlib.use('TkAgg') (which is never
appropriate when using TkAgg.  Pleas explain to us a little more
clearly what you are trying to do: are you embedding matplotlib in a
UI, if so which on?  Are you using it interactively from the python
shell (if so, which one?)

Note that if you are trying to build an app, as you suggest, ie embed
matplotlib in a GUI, you should not be using pylab at all.  You should
follow the lead of examples/embedding_in_YOURGUI*.py , eg those at
http://matplotlib.sf.net/examples
