GGRID Call

draws a grid

CALL GGRID( , , style<, color<, window<, viewport>);

The inputs to the GGRID subroutine are as follows:

and

are vectors of points used to draw sequences of lines.

style

is a numeric matrix or literal that specifies an index corresponding to a valid line style.

color

is a valid SAS color, where color can be specified as a quoted text string (such as 'RED'), the name of a character matrix containing a valid color as an element, or a color number (such as 1). A color number refers to the th color in the color list.

window

is a numeric matrix or literal specifying a window. This is given in world coordinates and has the form

{minimum-x minimum-y maximum-x maximum-y}

viewport

is a numeric matrix or literal specifying a viewport. This is given in normalized coordinates and has the form

{minimum-x minimum-y maximum-x maximum-y}

The GGRID subroutine draws a sequence of vertical and horizontal lines specified by the and vectors, respectively. The start and end of the vertical lines are implicitly defined by the minimum and maximum of the vector. Likewise, the start and end of the horizontal lines are defined by the minimum and maximum of the vector. The grid lines are drawn in the same color and line style. The coordinates in use for this graphics command are world coordinates.

For example, use the following statements to place a grid in the lower-left corner of the screen:

  
     x={10,20,30,40,50}; 
     y=x; 
  
        /* The following GGRID command places a GRID       */ 
        /* in the lower left corner of the screen,         */ 
        /* assuming the default window and viewport        */ 
     call ggrid(x,y); 
     call gshow;
