Missing line in a self-sufficient example in navigation_toolbar.rst :: a minor bug in docs #5645
Description
(see at the bottom http://matplotlib.org/users/navigation_toolbar.html )
I presume such examples are designed to be self-sufficient, and therefore instead of
from matplotlib.figure import Figure
from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg as FigureCanvas
from matplotlib.backends.backend_gtkagg import NavigationToolbar2GTKAgg as NavigationToolbar
it should contain
import gtk
from matplotlib.figure import Figure
from matplotlib.backends.backend_gtkagg import FigureCanvasGTKAgg as FigureCanvas
from matplotlib.backends.backend_gtkagg import NavigationToolbar2GTKAgg as NavigationToolbar
as shown in another example http://matplotlib.org/examples/user_interfaces/embedding_in_gtk.html
