[Gnuplot-info] 3D function

[Zhong R. <re...@uc...>]

Hi,

I have a 3D function f(x, y, z) in form of a data file of 4
columns x, y, z, and f.  The distribution of the function
value f is symmetrical around 0 following a normal
distribution.  What is the best way to represent this kind of
data in Gnuplot?  Is there any example I can reference?  Some
software uses 3D net to represent contour surfaces.  Thanks
for any suggestions.
