[solved] Gnuplot behaves not as expected

view story

https://bbs.archlinux.org – Hello community,I'm facing quite a strange problem with Arch's Gnuplot package. I need to make a pm3d plot from point data, but want to hide the points and only show the interpolated surface. I asked how to do this on a maths forum and got the advice to use the "nosurface" option. But unfortunately this option has absolutely no effect for me. Following .plt file reset set datafile missing "-nan" set pm3d set xlabel "X" set ylabel "log t" set zlabel "log Epsilon(R,t)" show label unset surface splot "plotEpsilon.dat" u 4:2:3 t (HowTos)
