Title Body

I am starting to get some insight into interactive plotting with python and matplotlib using pyGTK+. Therefore I took a look at the example given at the matplotlib website . This is a short exerpt of the Code: #!/usr/bin/env python """ Example of embedding matplotlib in an application and interacting with a treeview to store data. Double click on an entry to update plot data """ import pygtk pygtk.require('2.0') import gtk from gtk import gdk import matplotlib matplotlib.use('GTKAgg') # or 'GTK' from matplotlib.backends.backend_gtk import FigureCanvasGTK as FigureCanvas from numpy.random import random from matplotlib.figure import Figure Ones I try to run this Script in the Terminal I get the following error: Traceback (most recent call last): File "gtk_spreadsheet.py", line 15, in <module> from matplotlib.backends.backend_gtk import FigureCanvasGTK as FigureCanvas File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/backend_gtk.py", line 33, in <module> from matplotlib.backends.backend_gdk import RendererGDK, FigureCanvasGDK File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/backends/backend_gdk.py", line 29, in <module> from matplotlib.backends._backend_gdk import pixbuf_get_pixels_array ImportError: No module named _backend_gdk I have python 2.7 and pygtk 2.24 installed. Can anyone figure out where the error is located? I think it might be connected to some linking issues?
