Question on cntrrparam and splot

Show all headers | View raw

Moin moin,

I have here several data files (gridded data, ASCII) on which i use
normally splot together with pm3d... so far so good:-)

e.g.

www.enhydralutris.de/Fahrrad/Goniometer/Bilder/gox20051120_50m.html

What I want to do now: scale the data so, that they are normalized (to
slightly above one) and plot only contours at two levels (0.2 and 1) and
no pm3d... so far, so easy

set cntrparam levels 0.2,1

but with several files... in one plot i get for each file a set of
legend with different colors...for ten or so files it will confuse a
little bit the viewer:-(

How to mark them, that they can be  differentiated like in

plot "filea" u 1:2 title "example1, "fileb" u 1:2 t "example b"

?

One color per plotted file will be enough.

Preprocessing the splot-data to find the contours, that they can be
dealed with plot?

Greetings,

Olaf
