Hi to all,

I'm writing a web application with zope+python. I've made a first try to insert a graph using zope external  method an following the instruction reported in this sample:


I have some problem with the imports; zope tell me:

                  Error Type: ImportError
                  Error Value: cannot import name FigureCanvasAgg

This is due to the instruction 7:

   1 import matplotlib
   2 matplotlib.use('Agg')
   3 from pylab import *
   4 from os import *
   5 from StringIO import StringIO
   6 from PIL import Image as PILImage
   7 from matplotlib.backends.backend_agg import FigureCanvasAgg

The path of the file backends_agg.py  is correct. Have you got any suggestion.
