CSSM Procedure
ODS Graphics
Statistical procedures use ODS Graphics to create graphs as part of their output. ODS Graphics is described in detail in the "Statistical Graphics Using ODS" chapter in SAS/STAT User's Guide.
Before you create graphs, ODS Graphics must be enabled (for example, by using the ODS GRAPHICS ON statement). For more information about enabling and disabling ODS Graphics, see the section "Enabling and Disabling ODS Graphics" in that chapter.
The overall appearance of graphs is controlled by ODS styles. Styles and other aspects of using ODS Graphics are discussed in the section "A Primer on ODS Statistical Graphics" in that chapter.
You can refer to every graph produced through ODS Graphics with a name. The names of the graphs that PROC CSSM generates are listed in Table 10, along with the required statements and options.
