[Octave-bug-tracker] [bug #42561] gnuplot colors incorrect for 'demo trimesh'

[Rik]

Follow-up Comment #24, bug #42561 (project octave):

We'll have to see how Matlab behaves, but Octave is calculating the index as


clim = caxis ();
num_colors = rows (colormap);
idx = @(x) fix (num_colors * (x - clim(1)) / (clim(2) - clim(1)))


The idx is a zero-based ranged so the idx is [0, num_colors-1].
