POLYLINE Function
Specifies the beginning point of a polyline, which
is a connected series of line segments. This function is used in conjunction
with one or more POLYCONT functions to draw a series of connected
straight lines.
Requirement: |
The SG annotation data set must also specify at least
one instance of the POLYCONT function immediately after the POLYLINE
function.
|
Note: |
The POLYLINE object is similar to a POLYGON, except that
the POLYLINE object does not need to be a closed shape.

Syntax
Required Variables
- X1= numeric-value
- specifies the X coordinate of the annotation.
- Y1= numeric-value
- specifies the Y coordinate of the annotation.
Optional Variables
- DISCRETEOFFSET= numeric-value
- specifies an amount to offset the annotation from
a discrete value in data space. Specify a value from
-0.5 (left offset) to +0.5 (right offset).
- DRAWSPACE= “draw-space-value”
- specifies the drawing space and units for the annotation. DRAWSPACE can be used
rather than specify X1SPACE and Y1SPACE individually.
draw-space-value can
be one of the following:
Default:GRAPHPERCENT (unless overridden by a coordinate draw
space, such as X1SPACE)
Restriction:For the SGPANEL and SGSCATTER procedures, only GRAPHPERCENT,
GRAPHPIXEL, LAYOUTPERCENT, and LAYOUTPIXEL values are valid.
- LAYER= “BACK” | “FRONT”
- specifies whether the annotation is drawn in front
of (FRONT) or behind (BACK) the graph.
- LINECOLOR= “color” | “style-attribute”
- specifies a line color for the annotation. You can specify a color
or a style element attribute. Here is an example of a style attribute:
You
can specify colors using the same color schemes that are supported
by
SAS/GRAPH software.
For more information, see Color-Naming Schemes in SAS/GRAPH: Reference.
Default:COLOR attribute in the graph’s current style
- LINEPATTERN= “line-pattern”
- specifies a line pattern for the annotation. You can reference SAS patterns by number or by name. For a list of line patterns,
see Line Patterns.
Default:LineStyle attribute in the graph’s current
style
- LINETHICKNESS= n
- specifies the thickness of the line. You cannot specify
the unit of measure. The default unit of pixels is always used.
Default:LineThickness attribute in the graph’s current
style
- TRANSPARENCY= numeric-value
- specifies the degree of transparency for the annotation. Specify a value from
0.0 (completely opaque) to 1.0 (completely transparent).
- X1SPACE= “draw-space-value”
- specifies the drawing space of the annotation’s
X coordinate.
draw-space-value can
be one of the following:
Default:GRAPHPERCENT
Restriction:For the SGPANEL and SGSCATTER procedures, only GRAPHPERCENT,
GRAPHPIXEL, LAYOUTPERCENT, and LAYOUTPIXEL values are valid.
- XAXIS= “X” | “X2”
- specifies which X axis to use for data space annotations.
- XC1= “text-string”
- specifies the character X coordinate of an annotation.
- Y1SPACE= “draw-space-value”
- specifies the drawing space of the annotation’s
Y coordinate.
draw-space-value can
be one of the following:
Default:GRAPHPERCENT
Restriction:For the SGPANEL and SGSCATTER procedures, only GRAPHPERCENT,
GRAPHPIXEL, LAYOUTPERCENT, and LAYOUTPIXEL values are valid.
- YAXIS= “Y” | “Y2”
- specifies which Y axis to use for data space annotations.
- YC1= “text-string”
- specifies the character Y coordinate of an annotation.
