[Octave-bug-tracker] [bug #34523] surf() with gnuplot does not handle FaceColor correctly

[Dan Sebald]

Follow-up Comment #4, bug #34523 (project octave):

I've attached a changeset fixing the surface color setting.  It also adds
linestyle control for the lines of the surface.  Please give it a try.  Keep
in mind there are some limitations with hidden 3d behavior.  The line in your
example is not going to be properly segmented and displayed.  You may need to
do that manually.  Here is some sample script for you to experiment with:


graphics_toolkit("gnuplot");
figure();

[x, y] = meshgrid (-2:.2:2); 
t = linspace (-2, 2, 10); 
z = (1+x.*y).*(x+y); 
h = surf (x, y, z, "FaceColor", [.3 .5 .3], "EdgeColor", [0 0 0]);
hold on 
plot3 (t, t, t)

set(h, 'edgecolor', 'r')
set(h, 'linewidth', 3)
set(h, 'linestyle', ':')
set(h, 'facecolor', 'y')
