I assume you are using the gnuplot graphics_toolkit.  Gnuplot doesn't support 
changing the linestyle for the grid.

If your Octave is version 3.6.x, then I recommend you use the FLTK graphics 
toolkit.  Which supports changing the gridlinestyle.  The color for the grid 
will always be black.

If you desire some other color, you'll need to draw it using line objects.
