| The LOESS Procedure |
| ODS Graphics |
To request graphics with PROC LOESS, you must first enable ODS Graphics by specifying the ODS GRAPHICS ON statement. See Chapter 21, Statistical Graphics Using ODS, for more information. You can reference every graph produced through ODS Graphics with a name. The names of the graphs that PROC LOESS generates are listed in Table 50.6, along with the relevant PLOTS= options.
