Syntax

%PIEXY (angle, size);

Parameters

angle: specifies the angle used to calculate the point, relative to the center of the latest pie slice. The value can be a number, a numeric constant, or a numeric variable. For details, see the Annotate ANGLE Variable for the PIEXY function.

size: specifies the radius multiplier that works with the angle parameter to determine the location of the point. The value can be a number, a numeric constant, or a numeric variable. For details and valid values, see the Annotate SIZE Variable for the PIEXY function.

Details

This macro is useful when you want to label a pie chart or a circle.

When you use this macro, the Annotate facility expects a slice to have been previously drawn. If a slice has not been drawn or if the PIECNTR Function has not been processed, you can get erroneous results.
