[Gnuplot-info] how to plot 2d lines on 3d picture

[Gavin B. <gav...@gm...>]

If I understand you correctly this is a bit of a pain, but can be done
using multiplot. you usually have to set the size and ranges... heres
a script I used to plot a field using pm3d and overlay some points (2D
data, but splotted so the z axis is greater than the z-axis of the
pm3d plot).

Hope this helps.

reset
set xrange[10:54]
set yrange[10:54]
set cbrange[0:0.5]
unset ztics
set view 0,0
set size square

set term post color
set output 'out.ps'
set multiplot
set pm3d
set palette defined (0 "white", 0.5 "red")
unset surf
splot 'np333_field10000.dat' u 1:2:3
unset pm3d
set surf
splot 'np333_particle10000.dat' u 1:2:(1) w p pt 7 ps 0.5 lt -1
unset multiplot
set term x11
set output

!gv out.ps
