This has been fixed on the development branch, probably by this changeset.

summary:     Correct locations of minor grid lines for manual ticks (bug #45850).


The original reporter can wait until version 4.4 is released (but no schedule has been made) or build from Mercurial sources, which isn't too hard.

It works fine on dev snapshot but fails on 4.2.1
(there should be two more lines below -100)

Can you attach a screenshot?  This appears to work for me.

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
