GDRAWL Call

draws individual lines

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

The inputs to the GDRAWL subroutine are as follows:

is a matrix of points used to draw a sequence of lines.

is a matrix of points used to draw a sequence 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 GDRAWL subroutine draws a sequence of lines specified by their beginning and ending points. The matrices and must have the same number of rows and columns. The first two columns (other columns are ignored) of give the coordinates of the beginning points of the line segment, and the first two columns of have coordinates of the corresponding endpoints. If and have rows, lines are drawn. The first line is from to . The lines are drawn in the same color and line style. The coordinates in use for this graphics command are world coordinates. An example that uses the GDRAWL call follows:

  
       /* line from (25,25) to (50,50) - x and y take */ 
       /* default window range of 0 to 100    */ 
    call gdrawl({25 25},{50 50}); 
    call gshow;
