Purpose:    
            Overplot a grid on an existing coordinate box

Subject:    
            Graphics, plot grid, tickmarks

Syntax:     
            OVERPLOT/GRID [grid_type] [xy]
\ys\pa
            grid_type = grid_type; can be ``LARGE'' or ``SMALL''. LARGE means
                        that the grid will be put over the plot by connecting
                        the large tickmarks. SMALL means that the small and
                        large tickmarks will be connected. Default is LARGE
\ap\pa      
            xy        = connect the tickmarks on the x-axis (input X), on the 
                        y-axis (input Y) or both. Default is both tickmarks 
                        (=XY).

            OVERPLOT/GRID L XY
            Overplot a grid connecting the large ticks of the coordinate box
            both on the x- and y-axis.
