Re: Creating 3D Surface Plots From a Series of 2D Graphs

Show all headers | View raw

Hi Fred,

just write all 2D datasets to a single file, with a blank line
between each, so pm3d knows knows how to construct the grid.

Then

  splot "fname" using 1:(column(-1)*z_increment):2 with pm3d

for explanations see

 help pseudocolumn
 help pm3d

I your 2D datasets don´t have the same number of points (or they´re
not sampled evenly), pm3d´s "interpolate" option might be of interest.
