You're welcome.

In most of my examples, I put a call in to:

Canvas.ZoomToBB()

this set the zoom so that everything fits, but may not be what you want. 
You can pass in any bounding box you want to to ZoomToBB(), to show just 
what you need. Here's the method signature:

ZoomToBB(self, NewBB=None, DrawFlag=True)

You may want to do that too. You can set the Windows size in all the 
same ways that you way with any other wx.Window

All FloatCanvas DrawObjects have a Hide() and Show() method.

Does that help?
