Syntax

WHEN='B' | 'A' ;

B | A

specifies whether to draw the annotation before (B) or after (A) the graph. These values are not case sensitive. A missing value is equivalent to specifying B.

Note: The frame of some plot types is drawn before annotations where WHEN="B". If you use the Annotate facility to draw a background and you want your graph frame to be visible, then you can use the BAR function to draw a frame. The following annotate statements draw a white graph frame:

xsys="3"; ysys="3"; when="b";
function="move"; x=0; y=0; output;
function="bar"; style="solid"; color="white"; x=100; y=100; output;

Functions

You can use the WHEN variable with these functions:

BAR	MOVE	POINT
DRAW	PIE	POLY
DRAW2TXT	PIECNTR	POLYCONT
FRAME	PIEXY	SYMBOL
LABEL

Details

Normally, observations in an Annotate data set are processed sequentially. If you use the WHEN variable, all those observations with a WHEN value of B are processed first, the procedure output is then processed (if one is to be produced), and finally the observations with a WHEN value of A are processed.
