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, with 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.

PROC CLUSTER can produce plots of the cubic clustering criterion, pseudo F, and pseudo statistics, and a dendrogram. To plot a statistic, you must ask for it to be computed via one or more of the CCC, PSEUDO, or PLOT options.

You can reference every graph produced through ODS Graphics with a name. The names of the graphs that PROC CLUSTER generates are listed in Table 30.5, along with the required statements and options.
