Glad to see you are getting this working...

    self.figure =3D Figure()=20
    self.axes =3D self.figure.add_subplot(111)=20=20=20=20=20=20=20
    self.axes.plot(parent.listX,parent.listY, 'bo')=20=20=20=20=20=20
    self.axes.xlabel(parent.Xaxis.GetStringSelection())

    Jan> AttributeError: Subplot instance has no attribute 'xlabel'

Rather than giving you the answer, I'll show you how to find it....

You can use python's introspection capability (help, dir, type) to ask
an object about itself.  You can insert print statements directly into
your code

  print dir(self.axes)  # see below the results of dir(self.axes)

and look for methods that have the right names.  Or you can keep a
python shell open and use the python help system.  If for example, at
the shell you do help(self.axes), you'll find

  Help on instance of Subplot:
  <matplotlib.axes.Subplot instance>

So self.axes is a Subplot instance.  You can then import the Subplot
class and get much richer help by doing

  >>> from matplotlib.axes import Subplot
  >>> help(Subplot)=20=20


If you don't like working from the shell, head on over to the class
docs at http://matplotlib.sourceforge.net/classdocs.html and click on
the "axes" link and near the top of your screen you'll seen a link
that reads

  Subplot(SubplotBase, Axes)

That means the subplot class is derived from SubplotBase and Axes.
Click on Subplot, and read through the available methods.  If you get
impatient, search the web page for "xlabel"

Good luck!
