Hi Werner,

I think what you may want is something like this:

    def OnButton1Button(self, event):
        print 'done it'
        ### self.figure.clear()
        ### self.axes = self.figure.add_subplot(111)
        self.axes.cla()            # <-- clear the axes
        t = arange(0.0,4.0,0.01)
        s = sin(2*pi*t)

        self.axes.plot(t,s)
        self.axes.set_xlabel('Time 2 (s)')
        self.axes.set_ylabel('Price 2 ($)')
        self.canvas.draw()         # <-- force a redraw

Is that OK?  It works for me on Windows and Linux.  I do the
same thing for 'make a fresh plot' in my own codes that I know
work OK on Mac OS X as well.

Cheers,
