[SciPy-User] creating a 3D surface plot from collected data

[denis]

URI,
  can you try these --
    spline = sp.interpolate.Rbf(x,y,z,function='thin-plate',
smooth=1 )
    spline = sp.interpolate.Rbf(x,y,z,function='gaussian', smooth=1 )

pydoc scipy.interpolate.Rbf says
|  smooth : float, optional
|      Values greater than zero increase the smoothness of the
|      approximation.  0 is for interpolation (default), the function
will
|      always go through the nodal points in this case.

I have no idea if "smooth=1" is reasonable, but 0 is not a good
default -- Joe ?

cheers
