Unfortunately, I'm not able to get the svn version working :
imshow always fails :
/usr/lib/python2.4/site-packages/matplotlib/pyplot.py in imshow(*args,
**kwargs)
1673 hold(h)
1674 try:
-> 1675 ret = gca().imshow(*args, **kwargs)
1676 draw_if_interactive()
1677 except:
/usr/lib/python2.4/site-packages/matplotlib/axes.py in imshow(self, X,
cmap, norm, aspect, interpolation, alpha, vmin, vmax, origin, extent,
shape, filternorm, filterrad, imlim, **kwargs)
4435 im.autoscale_None()
4436
-> 4437 xmin, xmax, ymin, ymax = im.get_extent()
4438
4439 corners = (xmin, ymin), (xmax, ymax)
/usr/lib/python2.4/site-packages/matplotlib/image.py in get_extent(self)
286 sz = self.get_size()
287 #print 'sz', sz
--> 288 numrows, numcols = sz
289 if self.origin == 'upper':
290 return (-0.5, numcols-0.5, numrows-0.5, -0.5)
ValueError: need more than 1 value to unpack
but it is another topic.
