1-How can I rotate my plot so y would be the new x axis and vice versa?
2- Change the maximum value of y axis from 60 to 100.
The plot is created by this script in the terminal :
set palette grey
plot 'color_map.dat' matrix with image

Have you tried taking the transpose of the matrix before plotting it? As for axis scaling, look at the documentation: gnuplot.sourceforge.net/docs_4.2/node294.html7VoltCrayon– 7VoltCrayon2015-09-04 17:06:17 +00:00Commented Sep 4, 2015 at 17:06

You can exchange the x and y axes with the using modifier. (Just like for ordinary plots, except that for matrix data, columns 1 and 2 are not in your data file, but are inferred.)
plot 'color_map.dat' matrix using 2:1:3 with image
If you actually just want to change the maximum value on the y (new x) axis, you would use set xrange[:100]. But it sounds like you might actually want to scale the data itself, in which case you could use
plot 'color_map.dat' matrix using ($2/60.*100):1:3 with image
Try help plot matrix for more details.
