Re: [Gnuplot-info] Combining a 3D and a 2D splot with no surface

[<mg...@fi...>]

Thanks for your answer, this indeed seems to do the trick. However now the
key (which should show what contourline has which value) only shows
values, not the lines they correspond to, which makes it pretty useless
I'm afraid. I didn't include the key in the plot in my previous E-mail
because I thought it wouldn't be relevant but it seems to be.

To be more exact, I now use the following plotfile:

set terminal postscript eps enhanced monochrome
set output "output.eps"
set title "2009-11-24" offset 0,0.5
set size square
set xrange [1.01:1.2]
set yrange [0.85:0.99]
set xlabel "A"
set ylabel "B"
set xtics out nomirror
set ytics out nomirror
set key at 1.22,0.9
set colorbox vertical user origin .75,.45 size .03,.35
set data style lines
set pm3d at b interpolate 30,30
set contour
set cntrparam bspline
set view map
set surface
splot "results.dat" using ($2):($3):($1) with pm3d notitle, "line.dat"
using 1:2:(0) with lines notitle

Any idea how I can get the lines in the key back?

Kind regards,

Michiel
