OVAL Function

Draws an oval annotation around the specified (X1, Y1) coordinates using the specified height and width.
Tip: An easy way to draw a circle is to specify PIXEL for the HEIGHTUNIT and WIDTHUNIT variables and then provide the same value for the HEIGHT and WIDTH.

Syntax

FUNCTION= “OVAL”;

Required Variables

HEIGHT= numeric-value
specifies the height of the annotation. Specify a positive number greater than zero. You can use the HEIGHTUNIT variable to specify the unit of measurement.
Default:none
WIDTH= numeric-value
specifies the width of the annotation. Specify a positive number greater than zero. You can use the WIDTHUNIT variable to specify the unit of measurement.
Default:none
X1= numeric-value
specifies the X coordinate of the annotation.
Default:none
Y1= numeric-value
specifies the Y coordinate of the annotation.
Default:none

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).
Default:0.0 (no offset)
DISPLAY= “ALL” | “FILLED” | “OUTLINE”
specifies the fill and outline properties. You can specify that the annotation be filled (FILLED), have an outline (OUTLINE), or both (ALL).
Default:OUTLINE
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:
  • DATAPERCENT
  • DATAPIXEL
  • DATAVALUE
  • GRAPHPERCENT
  • GRAPHPIXEL
  • LAYOUTPERCENT
  • LAYOUTPIXEL
  • WALLPERCENT
  • WALLPIXEL
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.
See:For more information about these values, see Drawing Space Values.
FILLCOLOR= “color” | “style-attribute”
specifies a fill color for the annotation. You can specify a color or a style element attribute. Here is an example of a style attribute: GraphData2:Color
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
Interaction:This option takes effect only if the DISPLAY option is specified as FILLED or ALL.
FILLTRANSPARENCY= numeric-value
specifies the transparency for the fill portion of an annotation. Specify a value from 0.0 (completely opaque) to 1.0 (completely transparent).
Default:0.0
HEIGHTUNIT= “DATA” | “PERCENT” | “PIXEL”
specifies the dimension unit to use for the HEIGHT value.
Default:PERCENT
LAYER= “BACK” | “FRONT”
specifies whether the annotation is drawn in front of (FRONT) or behind (BACK) the graph.
Default:FRONT
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:
GraphData2:Color
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
ROTATE= degrees
rotates the annotation. Specify a number between 0 and 360.
Default:0
TRANSPARENCY= numeric-value
specifies the degree of transparency for the annotation. Specify a value from 0.0 (completely opaque) to 1.0 (completely transparent).
Default:0.0
WIDTHUNIT= “DATA” | “PERCENT” | “PIXEL”
specifies the dimension unit to use for the WIDTH value.
Default:PERCENT
X1SPACE= “draw-space-value”
specifies the drawing space of the annotation’s X coordinate.
draw-space-value can be one of the following:
  • DATAPERCENT
  • DATAPIXEL
  • DATAVALUE
  • GRAPHPERCENT
  • GRAPHPIXEL
  • LAYOUTPERCENT
  • LAYOUTPIXEL
  • WALLPERCENT
  • WALLPIXEL
Default:GRAPHPERCENT
Restriction:For the SGPANEL and SGSCATTER procedures, only GRAPHPERCENT, GRAPHPIXEL, LAYOUTPERCENT, and LAYOUTPIXEL values are valid.
See:For more information about these values, see Drawing Space Values.
XAXIS= “X” | “X2”
specifies which X axis to use for data space annotations.
Default:X
XC1= “text-string”
specifies the character X coordinate of an annotation.
Default:none
Y1SPACE= “draw-space-value”
specifies the drawing space of the annotation’s Y coordinate.
draw-space-value can be one of the following:
  • DATAPERCENT
  • DATAPIXEL
  • DATAVALUE
  • GRAPHPERCENT
  • GRAPHPIXEL
  • LAYOUTPERCENT
  • LAYOUTPIXEL
  • WALLPERCENT
  • WALLPIXEL
Default:GRAPHPERCENT
Restriction:For the SGPANEL and SGSCATTER procedures, only GRAPHPERCENT, GRAPHPIXEL, LAYOUTPERCENT, and LAYOUTPIXEL values are valid.
See:For more information about these values, see Drawing Space Values.
YAXIS= “Y” | “Y2”
specifies which Y axis to use for data space annotations.
Default:Y
YC1= “text-string”
specifies the character Y coordinate of an annotation.
Default:none
