history relinking なgnuplotのpm3dマップに，
擬似的に3次元にした2次元曲線を重ねるやりかた．
gnuplot> set xrange[-300:300] gnuplot> set yrange[-300:300] gnuplot> set dgrid3d 100,100 gnuplot> splot "/home/nakarx/gauss-space/world-data/world-c2-2-10000" u 1:2:3 with line gnuplot> set term table Terminal type set to 'table' gnuplot> set output "table.dat" gnuplot> replot gnuplot> set pm3d explicit map gnuplot> unset key gnuplot> splot "table.dat" with pm3d, "master/master-c2-2-10000-link0-rep1" u 8:9:10 with points gnuplot> splot "table.dat" with pm3d, "master/master-c2-2-10000-link0-rep1" u 19:20:10 with points
3フィールド目が0.1以下なら、0.1に無理矢理修正してぷろっと
splot "<awk '{print $1,$2,($3<0.1) ? 0.1 : $3}' world-data/world-c2-2-10000" u 1:2:3 with line
