[Octave-bug-tracker] [bug #43975] gnuplot eps output is in color

[Rik]

Follow-up Comment #12, bug #43975 (project octave):

I commented out the code which does "set palette" in __go_draw_axes__.m and
added a line to print out the value of the mono variable.


  fprintf (stderr, "mono is: %d\n", mono);
  #{
  if (length (cmap) > 0)
    fprintf (plot_stream,
             "set palette positive color model RGB maxcolors %i;\n",
             cmap_sz);
    fprintf (plot_stream,
             "set palette file \"-\" binary record=%d using 1:2:3:4;\n",
             cmap_sz);
    fwrite (plot_stream, [1:cmap_sz; cmap.'], "float32");
    fwrite (plot_stream, "\n");
  endif
  #}

The results from running the command below are:




octave:1> graphics_toolkit gnuplot
octave:2> surf (peaks)
mono is: 0
octave:3> print -dps a.ps
mono is: 1
mono is: 0
octave:4> drawnow ("postscript", "a2.ps", true, "a2.gp");
mono is: 1
mono is: 1


Attached are the actual postscript and .gp files.
