POLY Function
Specifies the beginning point of a polygon. Associated
variables can define the fill pattern and color, as well as the line
type that outlines the polygon.
Syntax
Associated Variables
- COLOR='color'
-
specifies the color
of the interior of the polygon, if a pattern is specified for the
STYLE variable. The outline color is specified with the POLYCONT
function. Color can be any
SAS/GRAPH color name.
- HTML='link-string'
-
specifies the text
that defines the link for drill-down.
- LINE=1...46
-
specifies the line
type that outlines the polygon. See
Specifying Line Types for an illustration of the line types.
- STYLE='fill-pattern'
-
specifies the value
of the pattern that fills the polygon. Fill-pattern can be the following map patterns:
- MSOLID
- MS
-
a solid pattern
- MEMPTY
- ME
-
an empty pattern
- Mdensity<style<angle>>
-
a
shaded pattern:
For example, if STYLE='MSOLID'
for the POLY function, the fill area that is drawn by the POLYCONT
sequence uses a solid fill. If STYLE='M5N15', the fill area uses
a shaded fill of parallel lines. The
fill-pattern value M5N15 specifies that the lines use the heaviest density, are
parallel, and are drawn at a 15-degree angle from the horizontal.
See also the discussion of fill patterns for maps in the documentation
for the VALUE= option for the
PATTERN Statement.
Note:Java and ActiveX support only SOLID and EMPTY. EMPTY
is the default if any other value is used.
- WHEN='B' | 'A'
-
specifies when to begin
the polygon in relation to other procedure output. See
WHEN Variable.
- X=horizontal-coordinate
- Y=vertical-coordinate
- Z=depth-coordinate (PROC G3D only)
- XC='character-type-horizontal-coordinate'
- YC='character-type-vertical-coordinate'
-
specify the initial
point of the polygon that is being created. Use the Z variable only
with the G3D procedure.
- XSYS='coordinate-system'
-
specifies the coordinate
system for the X or XC variable. Use the XC variable only with XSYS='2'.
See
XSYS Variable for an explanation of
coordinate-system.
- YSYS='coordinate-system'
-
specifies the coordinate
system for the Y or YC variable. Use the YC variable only with YSYS='2'.
See
YSYS Variable for an explanation of
coordinate-system.
- ZSYS='coordinate-system'
-
specifies the coordinate
system for the Z variable. See
ZSYS Variable for an explanation of
coordinate-system.
Details
Use POLY with POLYCONT
to define and fill areas in the graphics output. POLY and POLYCONT
do not update the (XLAST, YLAST) coordinates.
