The PRINCOMP Procedure

ODS Graphics

To request graphics with PROC PRINCOMP, you must first enable ODS Graphics by specifying the ods graphics on statement. See Chapter 21, Statistical Graphics Using ODS, for more information. Some graphs are produced by default; other graphs are produced by using statements and options. You can reference every graph produced through ODS Graphics with a name. The names of the graphs that PROC PRINCOMP generates are listed in Table 70.3, along with the required statements and options.
