dear list,
can someone tell me why I don't see anything when I run this script?
it is a modified version of the traits example...
I expected to see three plots with one line each...

on_trait_change, Property,cached_property, Bool

sizer.Add(toolbar,0,wx.EXPAND|wx.ALL,1)
panel.SetSizer(sizer)
canvas.SetMinSize((300,600))

if __name__=="__main__":

model.configure_traits(model.redraw())
thank you,
