OK that is the file that i looked into already. Is the backend
functionality i need really concentrated in only these files?
(amazing..)

I'll give it a try.

BTW is there a design document to get some grasp on the architecture of
matplotlib / pylab? It seems that most documentation concentrates on
describing pylab. Probably most people are using pylab (as i do most of
the time...).

Rein,

I don't think you need to change the wx backend to make a MPL plot
appear in a dockable pane.    You can definitely create a wx.Panel and
put a MPL Figure in it such as (untested code):

<untested code snippet>
import wx
import matplotlib
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg
from matplotlib.figure import Figure

class MyPlotPanel(wx.Panel):
    def __init__(self, parent, **kw):
        wx.Panel.__init__(self, parent, -1, **kw)
        self.fig = Figure(self,(6.0,4.0), dpi=96)
        self.axes = self.fig.add_axes([0.15,0.15,0.75,0.75])
        self.canvas = FigureCanvasWxAgg(self,-1, self.fig)

</untested code snippet>

and then use self.axes.plot() (or other methods) and canvas.draw().
Of course, you'll have to put that Panel someplace.   I haven't tried
to make a plot in a dockable window myself, but I'd be surprised if
you couldn't do it.

Take a look at wxmpl   http://agni.phys.iit.edu/~kmcivor/wxmpl/
and/or my own PlotPanel code from MPlot:
http://cars9.uchicago.edu/~newville/Python/MPlot/
and/or read http://www.scipy.org/Cookbook/Matplotlib/EmbeddingInWx
for more hints and examples.

Cheers,

Thanks!

does this also allows the use of the pylab interface? I would like to
use pylab from the command line (in a pycrust shell that i can embed in
a dockable window) and let the figures pop-up in a dockable window too.
But still from the command line use the same commands as i would for
pylab from say ipython.

Regards
Rein

But he wants to use pylab in a shell in his wx environment....

pretty much - - there is a pretty tight segregation between the figure
and the gui.

backend_template.py and backend_bases.py are good starting points.
There is a chapter in the user's guide and some resources at
http://matplotlib.sourceforge.net/faq.html#OO
