GDRAW Call |
The GDRAW subroutine is a graphical call that draws a polyline.
The required arguments to the GDRAW subroutine are as follows:
is a vector that contains the horizontal coordinates of points used to draw a sequence of lines.
is a vector that contains the vertical coordinates of points used to draw a sequence of lines.
The optional arguments to the GDRAW subroutine are as follows:
is a numeric matrix or literal that specifies an index that corresponds to a valid line style.
is a valid SAS color, where color can be specified as a quoted text string (such as 'RED'), the name of a character matrix that contains a valid color as an element, or a color number (such as 1) that refers to a color in the color list.
is a numeric matrix or literal that specifies a window. This is given in world coordinates and has the form
{minimum-x minimum-y maximum-x maximum-y} |
is a numeric matrix or literal that specifies a viewport. This is given in normalized coordinates and has the same form as the window argument.
The GDRAW subroutine draws a sequence of connected lines from points represented by values in x and y, which must be vectors of the same length. If x and y 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:
call gstart; /* line from (50,50) to (75,75) */ call gdraw({50 75},{50 75}); call gshow;
