Follow-up Comment #8, bug #49260 (project octave):

I expanded the code to better see how scatter is getting a different color in
gnuplot than in fltk.

close all
x = rand (1,1);
y = rand (1,1);
colors = rand (1,1);

graphics_toolkit gnuplot
scatter (x,y, [], colors, "filled")
colormap (rainbow (3));

title ("gnuplot");
graphics_toolkit fltk
scatter (x,y, [], colors, "filled")
colormap (rainbow (3));
title ("fltk");

With only three colors in the colormap, gnuplot always chooses the last one
while fltk always chooses the middle one.
