i have the usual 3d data file,

# results of a complex simulation
0  0 1
0 10 2
0 20 3

1  0 3
1 10 3
1 20 3

2  0 5
2 10 4
2 20 3

what i want to do is to plot a contour map (and now i have a graph
with all the details in place) and also a section of the surface, 

set pm3d map; set contour
splot 'results'  with pm3d title 'P_{max}'
plot 'results' where y=10 w l t "P_{max}(x,10)"

is it possible or i have to massage the data file? as in 

plot '< awk 'NF==3&&$2==10{print $1,$3} results' w l t "P_{max}(x,10)"
--

improbabile.                                        -- PLS, in IFQ
