GDRAW Call
draws a polyline
- CALL GDRAW( x, y<, style><, color><,
window><, viewport>);
The inputs to the GDRAW subroutine are as follows:
- x
- is a vector containing the x coordinates
of points used to draw a sequence of lines.
- y
- is a vector containing the y 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 n refers to the nth 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 x and
y, which must be vectors of the same length.
If x and y have n points, there will be n-1 lines.
The first line will be from the
point (x(1),y(1)) to (x(2),y(2)).
The lines are drawn in the same color and line style.
The coordinates in use for this
graphics command are world coordinates.
An example using 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;
