hello,
thanks for answering. I actually fail with the import :
In [1]: from matplotlib import axes3d
···
---------------------------------------------------------------------------
ImportError Traceback (most recent call last)
/home/cohen/bstw/<ipython console> in <module>()
/usr/lib/python2.5/site-packages/matplotlib/axes3d.py in <module>()
14 from axes import Axes
15 import cbook
---> 16 from transforms import unit_bbox
17
18 import numpy as npy
ImportError: cannot import name unit_bbox
any idea?
----------------------------------------------------------------------

I think scatter3D does what you want:
from matplotlib import axes3d
import pylab as pl
fig = pl.figure()
ax = axes3d.Axes3D(fig)
ax.scatter3D(data[:,0],data[:,1],data[:,2])
ax.set_xlabel('X value')
ax.set_ylabel('Y value')
ax.set_zlabel('Z value')
pl.show()
You could also change the colour and size of each point based on other
array values:
col = ax.scatter3D(data[:,0], data[:,1], data[:,2], c=data[:,3],
cmap=pl.cm.jet, s=data[:,4])
cbar = fig.colorbar(col,shrink=0.9,extend='both')
cbar.ax.set_ylabel('axis 3 data values')
Pretty nifty.

The axes3d stuff is not currently working on the SVN trunk. You probably want to use 0.91.2 or the v0_91_maint branch in SVN instead.
Cheers,
Mike
