Re: [Gnuplot-info] Coloring 2D data points - No palette interpolation

[Thomas S. <t.s...@fz...>]

either define your own color palette, e.g.:
    set palette functions 0,(gray>0.5?1.:0.),(gray<=0.5?1.:0.)
or reduce the number of colors:
    set palette maxcolors 2

the actual palette can be viewed with
    test palette
