FUNCTION Variable

FUNCTION Variable

Specifies a graphics command or programming function for the Annotate facility to perform.

Type: character

Length: 8

Default: LABEL

Syntax

FUNCTION='function-name';

function-name

specifies the name of an Annotate function. Values for function-name are

BAR	draws and, optionally, fills a rectangle.
CNTL2TXT	copies (XLAST, YLAST) to (XLSTT, YLSTT), overwriting the previous values of (XLSTT, YLSTT).
COMMENT	places comments in your data set. The observation is ignored when the data set is processed.
DEBUG	writes the values of all Annotate variables to the SAS log before and after the next observation.
DRAW	draws a line in the graphics output.
DRAW2TXT	draws a line from (XLAST, YLAST) to (XLSTT, YLSTT).
FRAME	draws a border around the area defined by XSYS and YSYS. It also to specifies a background color for the framed area .
LABEL	draws text and is the default for the FUNCTION variable.
MOVE	moves to the specified point (does not draw a line).
PIE	draws a pie slice, arc, or circle that can be filled.
PIECNTR	sets new center and radius values. The PIEXY function can use this information in a later observation. PIECNTR does not draw a pie.
PIEXY	returns the coordinates of a point on a pie slice. Other functions can use this information in a later observation.
POINT	draws a point.
POLY	begins drawing a polygon (first vertex). Use the POLYCONT function in successive observations to supply the remaining vertices.
POLYCONT	continues drawing a polygon.
POP	gets values from the LIFO stack and changes the current value of (XLAST, YLAST) and (XLSTT, YLSTT) to those values.
PUSH	puts the current values for (XLAST, YLAST) and (XLSTT, YLSTT) in the LIFO stack.
SWAP	exchanges the values of (XLAST, YLAST) and (XLSTT, YLSTT).
SYMBOL	draws a symbol. See Special Symbols for Plotting Data Points for a list of the symbols.
TXT2CNTL	copies the values (XLSTT, YLSTT) to (XLAST, YLAST), overwriting the previous values of (XLAST, YLAST).

All other variables in the observation that contain the function act as parameters for the action. For a detailed description of each function and the Annotate variables that can be used in conjunction with it, see Annotate Functions.
