Details:

In case of graphics_toolkit "fltk" and "qt" minor y-grid lines -104 and -108
are missing.

Best regards Poul-Erik.

Example code:

close all;

for i = 1:3,        
      switch (i)
        case 1
          tool_kit_name = "gnuplot";
          status        = '';
        case 2
          tool_kit_name = "fltk";
          status        = 'Missing y-grid line -104 and -108';
        otherwise
          tool_kit_name = "qt";
          status        = 'Missing y-grid line -104 and -108';
      endswitch
      graphics_toolkit (tool_kit_name);
      figure(i);

      semilogx([ 100 5000 12000 ], [ 0 0 -110 ] );
      grid;
      grid ("minor", "on");
      title (sprintf ("%s \n%s", tool_kit_name, status));
      axis ([ 100 12000 -110 5 ]);
       
endfor
