GDRAW Call

draws a polyline

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

The inputs to the GDRAW subroutine are as follows:

is a vector containing the coordinates of points used to draw a sequence of lines.

is a vector containing the coordinates 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 GDRAW subroutine draws a sequence of connected lines from points represented by values in and , which must be vectors of the same length. If and have points, there will be lines. The first line will be from the point 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 GDRAW subroutine follows:

  
       /* line from (50,50) to (75,75) - x and y take */ 
       /* default window range of 0 to 100            */ 
    call gdraw({50 75},{50 75}); 
    call gshow;
