This is to plot 3d surfaces in a 2d representation. You only have two coordinates, ie a 2d plot. I did: set palette splot '3cols.dat' us 1:2:3 w p palette I don't know if that's what you want? > set palette rgb 33,13,10 > set view map > set cbrange [1:4] > ssplot "3cols.dat" with points palette pt 9 > > > However, a knowledgeable soul at the Gnuplot mailing list has informed > me that using pm3d is a bad idea (the above command spews out warnings > about not enough isosamples) and I should use 'plot' command for this. > But he did not follow that up with a little example. The knowledgeable soul told you to read the manual. # aptitude install gnuplot-doc as ordinary user within a directory for personal documentation: $ cp /usr/share/doc/gnuplot-doc/gnuplot.ps.gz . $ gunzip gnuplot.ps.gz $ ps2pdf gnuplot.ps $ kpdf gnuplot.pdf You'll want to read pp. 64ff. (For me this is more convenient, but of course there are other ways to read the gzipped ps.)
