Hi,
I can set palette gray


   set palette functions gray,gray,gray

then it is linear gradient and gray means linear function f(x) = x

If I set :


  set palette gray

then it is nonlinear gradient : https://stackoverflow.com/questions/32914627/gnuplot-intensity-plot-with-grayscale


What means gray here?
Where can I find code for set palette gray ?

TIA

Adam

I can also check:
gnuplot> show palette
palette is GRAY
figure is POSITIVE
all color formulae ARE NOT written into output postscript file
allocating ALL remaining color positions for discrete palette terminals
Color-Model: RGB
gamma is 1.5

gnuplot> show palette gradient
color mapping *not* done by defined gradient.

but it gives no new informations
