You can select one of the following two types of graphics in PROC LIFEREG: ODS and traditional. ODS Graphics is the preferred method of creating graphs, superseding traditional graphs.
When ODS Graphics is enabled, you can use the PLOTS= option in the PROC LIFEREG statement to create plots by using ODS Graphics. For more information about ODS Graphics options, see the PLOTS= option. If ODS Graphics is not enabled, then traditional graphics are produced.
You can specify the following option in the PROC LIFEREG statement:
The following options control the appearance of the box in the INSET statement when you use traditional graphics. These options are not available if ODS Graphics is enabled. Table 11 summarizes the options available in the INSET statement.
Table 11: INSET Statement Options
| Option | Description |
|---|---|
| CFILL= | Specifies the color for the filling box |
| CFILLH= | Specifies the color for the filling box header |
| CFRAME= | Specifies the color for the frame |
| CHEADER= | Specifies the color for text in the header |
| CTEXT= | Specifies the color for the text |
| FONT= | Specifies the software font for the text |
| HEADER= | Specifies the text for the header or box title |
| HEIGHT= | Specifies the height of the text |
| NOFRAME | Omits the frame around the box |
| POS= | Determines the position of the inset |
| REFPOINT= | Specifies the reference point for an inset |
All options are specified after the slash (/) in the INSET statement.
Table 12 summarizes the options available in the PROBPLOT statement for traditional graphics.
