# 3d plotting question

Forwarding this to the list....

I'm curious if you run into another problem I recently reported. Can you do, e.g.:

import copy
import pylab as P
import matplotlib.axes3d as P3
def test() :
[X,Y] = P.meshgrid(P.linspace(-3,3,7),P.linspace(-3,3,7))
Z = copy.deepcopy(X)
Z1 = copy.deepcopy(X)
for i in xrange(len(X)) :
for j in xrange(len(X[0])) :
Z[i][j] = X[i][j]*Y[i][j]
Z1[i][j] = X[i][j]*Y[i][j] - 5
P.close('all')
fig = P.figure()
ax = P3.Axes3D(fig)
ax.plot3d(ravel(X),ravel(Y),ravel(Z),'r.-')

or do you instead get an error in matplotlib's axes.py, complaining about self.autoscale_view and a scalex parameter? For more on the hack I made to axes.py file which then allowed me to use plot3d, see http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg03041.html.

I also seem to have some other 3D plotting problems. Again, following
some of the demo/test advice in the cookbook, I tried things like

import pylab as p
import matplotlib.axes3d as P3
P3.test_surface()

I too just encountered the same problem - what is the last version of
mpl for which doing this worked? (I'm using 0.9 revision 3131)
