The ICLIFETEST Procedure

ODS Graphics

Statistical procedures use ODS Graphics to create graphs as part of their output. ODS Graphics is described in detail in Chapter 21: Statistical Graphics Using ODS.

Before you create graphs, ODS Graphics must be enabled (for example, by specifying the ODS GRAPHICS ON statement). For more information about enabling and disabling ODS Graphics, see the section Enabling and Disabling ODS Graphics in Chapter 21: Statistical Graphics Using ODS.

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 Chapter 21: Statistical Graphics Using ODS.

The survival plot is produced by default; other graphs are produced by specifying the PLOTS= option in the PROC ICLIFETEST statement. You can refer by name to every graph produced through ODS Graphics. The names of the graphs that PROC ICLIFETEST generates are listed in Table 49.5, along with the required keywords for the PLOTS= option.
