Coincidentally, I was also working on a different embedding_in_wx3
which shows how to use a custom toolbar, in response to another
question off list.  I changed the name submitted that as
embedding_in_wx4 :-)

What was the bug?  I didn't notice any problems with lower.

BTW, the recommended way to set rc params in now with the rc command.
This was initially defined in matplotlib.matlab but I just moved it to
matplotlib.__init__.py to make it accessible to application
developers.  You can do

  matplotlib.rc('image', origin='lower')

and set multiple image params with multiple kwargs.

        self.toolbar.update() # Not sure why this is needed - ADS

This updates the Axes menu on the toolbar, which is needed if the
number of axes have changed.  Since the number of axes/subplots can
change after the figure/toolbar was created, this tells the toolbar to
update it's axes menu.

Another comment: try not to use x.resize in matplotlib examples,
because of the Numeric bug (did you get the emails Todd and I
exchanged regarding this?).  Numeric segfaulted for me when I
initially ran your example with the .resize command.

Note that matplotlib.mlab has the meshgrid command for building mesh
arrays from 2 1D vectors.  I replaced your code with

        x = numerix.arange(120.0)*2*numerix.pi/60.0
        y = numerix.arange(100.0)*2*numerix.pi/50.0
        self.x, self.y = meshgrid(x, y)
        z = numerix.sin(self.x) + numerix.cos(self.y)


Finally, there seems to be a figure size problem on linux: when I run
your example the figure window is too small and the image wraps.

Updates are in CVS - thanks for the submission.
