Hi there,
I can plot 2D data on a color-map with parametric x,y,z values, i.e. the following works as needed:
reset;set pm3d map interpolate 1,1;set size ratio -1;splot "xyz.txt" notitle
where "xyz.txt" contains:
1.000000000000000E+00 0.000000000000000E+00 0.000000000000000E+00

MY PROBLEM:
I want to store the data in a binary file "xyz.bin" and reproduce the same figure.
MY QUESTIONS:
- how to arrange data in the binary file
- how to produce the plot (i guess, I need the right 'record' setting)
meanwhile I tried the following
* I made a datafile containing the float numbers:
1 1 1 2 2 2 3 3 3 4 4 4 5 5 5 0 1 2 0 2 4 0 3 6 0 4 8 0 5 10 0 1 2 0 4 8 0 9 18 0 16 32 0 25 50
and I called something like
reset;set pm3d map interpolate 1,1;splot "xyz.bin" binary format="%double" record=.....
without success! who can help, please?
cheers, kdliss
