Mapping 3d data on a 2d color map
Gnuplot has a very easy and straightforward way to convert a x-y-z data into a 3d plot or a 2d color map. Let's write the data in the form;
1 1 0.0
1 2 0.4451
1 3 0.4249
2 1 0.13142
2 2 0.0
2 3 0.983
3 1 xxx
3 2 xxx
3 3
A space between chunks of data is important. Using commands below you can get a 2d plot;
set size square
set pm3d map # Remove the word 'map' to get a 3d plot
set xrange [1:261] # Change the range to suit your needs
set yrange [1:261]
splot 'all.dat'
1 1 0.0
1 2 0.4451
1 3 0.4249
2 1 0.13142
2 2 0.0
2 3 0.983
3 1 xxx
3 2 xxx
