[Octave-bug-tracker] [bug #42561] gnuplot error on "demo trimesh"

[Avinoam Kalma]

Follow-up Comment #7, bug #42561 (project octave):


Hi,

there are few problems with gnuplot plotting of trimesh,
like colormap problems, but according to gnuplot documentation, 
pm3d plots surface, and trimesh should plot only the mesh.
To get trimesh working, two lines should be changed

   fputs (plot_stream, "set pm3d implicit;n");
(line 1407) should not be written  but
   fputs (plot_stream, "set pm3d explicit;n");

and line 679 "sprintf ("with pm3d");" should be (for mesh only!)
"sprintf ("with lines");"

These changes will not solve the problem shown in comment#6,
but show the mesh lines in demo trimesh

Avinoam
