Input Data Sets
DATA= Data Set
The DATA= data set provides the set of variables that are analyzed. The UNIVARIATE procedure must have a DATA= data set. If you do not specify one with the DATA= option in the PROC UNIVARIATE statement, the procedure uses the last data set created.
ANNOTATE= Data Sets
You can add features to plots by specifying ANNOTATE= data sets either in the PROC UNIVARIATE statement or in individual plot statements.
Information contained in an ANNOTATE= data set specified in the PROC UNIVARIATE statement is used for all plots produced in a given PROC step; this is a “global” ANNOTATE= data set. By using this global data set, you can keep information common to all high-resolution plots in one data set.
Information contained in the ANNOTATE= data set specified in a plot statement is used only for plots produced by that statement; this is a “local” ANNOTATE= data set. By using this data set, you can add statement-specific features to plots. For example, you can add different features to plots produced by the HISTOGRAM and QQPLOT statements by specifying an ANNOTATE= data set in each plot statement.
You can specify an ANNOTATE= data set in the PROC UNIVARIATE statement and in plot statements. This enables you to add some features to all plots and also add statement-specific features to plots. See Example 4.25.
