I am using gnuplot. I would like to compare across different settings of the same type of data in a color plot using something like the following:
plot 'pdratio' using 1:2:(abs($1)>0.3?$4:1/0) with p ps 0.75 pt 4 palette
Gnuplot automatically chooses the data range for the palette to map out color, which can be different from case to case. Is there a way to ask gnuplot to map out colors for the same data range consistently across different cases?
set palette maxcolor 100 would not be adequate for my purposes.
