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

[Rik]

Follow-up Comment #23, bug #42561 (project octave):

I extracted the relevant segment of the mesh from the demo and created a
simpler example.  The data and the file to run are attached.

The code in tst_bad_gnup_mesh.m is


load meshtst.var
close all
graphics_toolkit fltk
figure ("colormap", [1 0 0; 0 1 0; 0 0 1]);
hm = mesh (x, y, z, cdata)
h2 = copyobj (1)
graphics_toolkit (h2, "gnuplot")
figure (1)
title ("FLTK");
figure (2)
title ("gnuplot");


This uses a 3-color colormap of Red/Green/Blue so the difference is quite easy
to see.  This might be round-off error.
