[Matplotlib-users] problem with histogram

[Antonino C. <cuc...@as...>]

Hello list,
I am trying to run the "histogram_demo_extended.py" on my mac 10.5.
I installed matplotlib through the scisoft package.
The normal hist command works fine but when I tried to use "align" or 
"histtype" keyward I get this kind of error:

[Macintosh-2:~/optional/examples/pylab_examples] nino% 
./histogram_demo_extended.py                                 
Traceback (most recent call last):
  File "./histogram_demo_extended.py", line 15, in <module>
    n, bins, patches = P.hist(x, 50, normed=1, histtype='stepfilled')
  File 
"/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/pyplot.py", 
line 1633, in hist
    ret =  gca().hist(*args, **kwargs)
  File 
"/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/axes.py", 
line 5064, in hist
    p.update(kwargs)
  File 
"/scisoft/i386/library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/artist.py", 
line 394, in update
    raise AttributeError('Unknown property %s'%k)
AttributeError: Unknown property histtype

Can someone give me any advice?
Thanks a lot in advance.

nino
