Annotate Functions

In an Annotate data set, the value of the FUNCTION variable specifies what action the observation performs. Annotate functions act in conjunction with Annotate variables that determine where and how to perform the action. Many of these variables are function-dependent, that is, what they do depends on the function they are used with. For example, with the LABEL function the STYLE variable specifies a font; with the BAR function, STYLE specifies a pattern.

This section describes all of the values of the FUNCTION variable. For each function it

describes the function's action.
notes whether the function updates the internal coordinate variables XLAST, YLAST and XLSTT, YLSTT.
describes how other Annotate variables behave with the function. For a complete description of each variable, see Annotate Variables.

For a summary of drawing and programming tasks performed by the FUNCTION variable, see Summary of Graphics Tasks Performed by Annotate Functions.

The variables that are available for use with each function are listed in Annotate Variables used with Annotate Functions.
