[Matplotlib-users] Question to OO matplotlub tutorial

[Florian L. <mai...@xg...>]

Hello,
taken form the tutorial http://matplotlib.sourceforge.net/leftwich_tut.txt I 
use the code:

from matplotlib.backends.backend_agg import FigureCanvasAgg as FigureCanvas
from matplotlib.figure import Figure

fig = Figure()
canvas = FigureCanvas(fig)
ax = fig.add_subplot(111)
ax.plot([1,2,3])
ax.set_title('hi mom')
ax.grid(True)
ax.set_xlabel('time')
ax.set_ylabel('volts')
canvas.print_figure('test')

Which IMO uses the AGG backend (which works fine for my using the pylab 
interface).

But upon excecution I get:

No module named pygtk
PyGTK version 1.99.16 or greater is required to run the GTK Matplotlib 
backends


What is wrong there?

Thx,

Florian
