[Gnuplot-info] Choosing linetype of contour plot lines

[murt <mu...@gm...>]

Hello everyone,

My rough setup is the following:

unset surface
set view map

set multiplot

set style data pm3d
set pm3d ...
splot DATA_A1, DATA_A2, ...
unset pm3d

set contour base
set cntrparam levels discrete VAL_B ...
splot DATA_B

set cntrparam levels discrete VAL_C ...
splot DATA_C

unset multiplot

This is working very fine to plot a map of data (DATA_Ax) and two
contour overlays from different data (DATA_B, DATA_C). But it shows,
that both single contour lines (VAL_B and VAL_C) were plotted in the
same linetype (and color too).

So my questions are: Is there a way to set explicitly the linetype of
following contour plot lines? Or is it possible to set a linetype bias
and increment for contour lines?

My actual gnuplot file(s) (each splot in above example is a "load" of a
generic gnuplot file) makes use of my own predefined linetypes. This
works very well for choosing linetypes for surfaced plots (w/ "hidden3d
offset ..."). I think I am looking for something similar for contour
lines.

I am using gnuplot 4.6 patchlevel 0 on arch linux.

I would be very happy if someone of you could help me with this
struggle.

Many thanks to everyone,

Stephan
