contourf3D and contour3D seem to be broken in my copy of matplotlib 0.87.5 that I installed from ubuntu edgy's repositories. Is this a known problem? I started going through axes3d.py etc and fixing the reported errors, but the error trail seems to go pretty deep across multiple files. Now I'm wondering if maybe this is something major that has already been fixed by more experienced hands in SVN or something.
In the off chance that this is an unknown problem, I've enumerated the errors below. These all happened while attempting to run the example code in http://www.scipy.org/Cookbook/Matplotlib/mplot3D If it's fixed in SVN, I'll try installing that, but I haven't seen this bug mentioned in matplotlib's bug list on sourceforge.net. -- Matt When I called contourf3D the first time, I got the following error: <snip> File "/usr/lib/python2.4/site-packages/matplotlib/axes3d.py", line 596, in contourf3D levels, colls = self.contourf(X, Y, Z, 20) TypeError: unpack non-sequence </snip> As suggested in the examples page above, I went into contourf3D's function definition in axes3d.py and replaced: levels, colls = self.contourf(X, Y, Z, 20) with C = self.contourf(X, Y, Z, *args, **kwargs) levels, colls = (C.levels, C.collections) I then got a new error when calling contourf3D: <snip> exceptions.NameError Traceback (most recent call last) /home/mkg/Desktop/<ipython console> /usr/lib/python2.4/site-packages/matplotlib/axes3d.py in contourf3D(self, X, Y, Z, *args, **kwargs) 604 zs = [z1] * (len(linec._verts[0])/2) 605 zs += [z2] * (len(linec._verts[0])/2) --> 606 art3d.wrap_patch(linec, zs, fn=draw_polyc) 607 self.auto_scale_xyz(X,Y,Z, had_data) 608 return levels,colls NameError: global name 'draw_polyc' is not defined </snip> After changing draw_polyc to art3d.draw_polyc, it complained that art3d.wrap_patch in fact only takes two arguments.
