[Matplotlib-users] how to customize informations given by the navigation toolbar ?

[LB <bra...@gm...>]

   Hi,


I'm using the twiny fonction to plot two functions on the same axes.
I would like to have both informations displayed on the navigation bar.
Now, I have :
  pan/zoom : x=220, y=80

Is-it possible to customize the toolbar in order to have
  pan/zoom : x1=220, x2=300, y=80
