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

> don't use 'notitle' in the 2nd plot

No that was not what I meant. If I don't use 'notitle' in the second plot,
a title for the data in line.dat is added, but I need a key which
indicates which contourline, generated in the first plot, corresponds to
which value.

I have created several images which hopefully will clarify the situation
(I apologize for the size of these images).

The first image is basically what I want, except I have not added a plot
for y=2-x yet, it is the situation I started out with:

The second image is what I got after your suggestion to use the first plot
"with pm3d" and to use "set surface". It is almost what I want but, as you
can see, in the key the lines behind the values 50,60,70 and 80 are
missing:

The third image is what I get after your suggestion to remove "notitle"
from the second plot, as you can see, the lines are still missing from the
key:

I do not know if what I want is possible, but I would sure like to find
out :)

Finally and to be complete, I use gnuplot 4.2 patchlevel 5 (which is
currently the default in the most recent release of Ubuntu).

Kind regards,

Michiel
