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

[Rik]

Follow-up Comment #11, bug #34523 (project octave):

@Dan: Overall this patch seems to be a big improvement, and I'm inclined to
apply it to the default branch.  I'm also attaching the results of the surf
plot commands for fltk and gnuplot.  There is still a difference in how much
of the line is displayed, but we can't always have everything.

One last issue is that I still get a warning from gnuplot


h = surf (x, y, z, "FaceColor", [.3 .5 .3], "EdgeColor", [0 0 0]);

gnuplot> set pm3d explicit at s hidden3d  linetype 1 linecolor rgb "#000000"
linewidth 0.500000  depthorder corners2color c3;
                                          ^
         line 0: invalid pm3d option

         line 0: invalid pm3d option



The caret marker, '^', is pointing to the "linetype" keyword.  Can we use
__gnuplot_version__ or some other mechanism to avoid this?  I think it will be
scary for users, even though gnuplot is really just saying that it is ignoring
the following construct.
