Does it work for you? I think all that's missing is another error in
case gnuplot is not available (which is now possible).

Something like

 function set_graphics_toolkit ()
   if (isempty (available_graphics_toolkits ()))
     error ("no graphics toolkit available for plotting");
   elseif (! strcmp ("gnuplot", graphics_toolkit ()) ...
      && ! octave_config_info ().features.OSMESA)
     if (! any (strcmp ("gnuplot", available_graphics_toolkits ())))
       error ("no graphics toolkit available for offscreen plotting");
     else
       graphics_toolkit ("gnuplot");
     endif
   endif
 endfunction

look ok?

If gnuplot is used not all figures can be drawn.  Is this useful?
