Re: [Gnuplot-info] lines in 3D

[Thomas S. <t.s...@fz...>]

you may add arrows without heads:

set xrange [0:pi]
set yrange [0:pi]
set samples 10
set arrow 1 from 0.5,0.5,0.5 to 2.5,0.5,0.5 nohead front
set arrow 2 from 2.5,0.5,0.5 to 2.5,2.5,0.5 nohead front
set arrow 3 from 2.5,2.5,0.5 to 0.5,2.5,0.5 nohead
set arrow 4 from 0.5,2.5,0.5 to 0.5,0.5,0.5 nohead
splot sin(x)*sin(y) with pm3d
