[Matplotlib-users] How to modify the navigation toolbar easily in a matplotlib figure window?

[Jianbao T. <jia...@gm...>]

Is it possible to do something like the following to modify the navigation
toolbar in matplotlib?

   1. Generate a figure window, such as by *fig = figure()*
   2. Get a reference of the navigation toolbar, such as by *tbar =
   fig.get_navigation_toolbar()* or better yet, just by *tbar = fig.navtbar*
   3. Modify the toolbar through the reference *tbar*, such as
   delete/add/edit a button by something like this: *tbar.add_button()*,
    *tbar.remove_button(a reference to a button)*,  *tbar.edit_button(a
   reference to a button)*.
   4. Update the figure by *fig.canvas.draw()*

Thank you very much.
