Hi Jan,

axes.xlabel doesnt exist. What you are looking for is 

self.axes.set_xlabel(parent.Xaxis.GetStringSelection())
self.axes.set_ylabel(parent.Xaxis.GetStringSelection())

The Matplotlib devs have put a lot of effort into documenting the project. In 
situations like this, I often end up relying on the python interactive 
interpreter to find the method I am looking for:

from pylab import *
fig = figure()
ax = fig.add_subplot(111)
dir(ax)

or you could add a line in your own code:

      self.figure = Figure()
      self.axes = self.figure.add_subplot(111)

      self.axes.plot(parent.listX,parent.listY, 'bo')
      print dir(self.axes)

both would give you a list of available methods.

Hope this helps,

Darren
