[Gnuplot-info] pm3d map + contour lines

[fly a. <vic...@gm...>]

Hi all.
I want to have a colormap combined with contour lines on one plot.
But if I do that I also get the lines (not contour lines, but those I'd get
if I just did splot 'file' u 1:2:3 without any other options specified)
plotted, which I don't want. Is there a way to just have countours and
colormap?
What I did was:

set style data pm3d
set pm3d map
# unset surface
set cntrparam levels 5
set samples 10
set cntrparam levels 25
set samples 100
set contour base
splot 'filename' using 9:10:5 title ""

So if I do in the last line: with lines palette 
then I get the unwanted extra lines.
If I don't, then I only get colormap and no contours...
Hope I made it clear. Any ideas?
