I try plot a 4d data file (x,y,z,intensity) assigning the color on the
basis of the intensity?
I see a similar example here:
http://gnuplot.sourceforge.net/demo_4.4/heatmaps.html
and using my data file I modify the splot command:
splot 'data.txt' using 1:2:3:4 with pm3d title "4 data columns x/y/z/color"
But I have the following error message:
Warning: Single isoline (scan) is not enough for a pm3d plot.
Hint: Missing blank lines in the data file? See 'help pm3d' and FAQ
Thanks in advanced!
