The VARIOGRAM Procedure
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.
For additional control of the graphics that are displayed, see the PLOTS option in the section PROC VARIOGRAM Statement.
PROC VARIOGRAM assigns a name to each graph it creates by using ODS Graphics. You can use this name to refer to the graph when using ODS Graphics. You must also specify the PLOTS= option indicated in Table 102.7.
