The COUNTREG Procedure

ODS Graphics

Subsections:

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 in SAS/STAT 13.2 User's Guide.

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 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.

This section describes the use of ODS Graphics to create graphics by using the COUNTREG procedure.

To request these graphs, you must specify the ODS GRAPHICS ON statement. There is no default plot for the COUNTREG procedure. If, in addition to the ODS GRAPHICS statement, you specify the ALL option in the PROC COUNTREG statement, then all applicable plots are created.

ODS Graph Names

PROC COUNTREG assigns a name to each graph that it creates using ODS. You can use these names to refer to the graphs when using ODS. The names are listed in Table 11.11.
