Customizing the Kaplan-Meier Survival Plot

Changing the Line Pattern

You can change the line patterns as follows:


%let GraphOpts = attrpriority=none
                 DataLinePatterns=(ShortDash MediumDash LongDash);


proc lifetest data=sashelp.BMT
              plots=survival(cb=hw test atrisk(outside maxlen=13));
   time T * Status(0);
   strata Group;

The results are displayed in FigureĀ 23.22.

Other values for the DATALINEPATTERNS= option are provided in the section The Macro Variables. You must use the option ATTRPRIORITY=NONE when you want to have varying line patterns in an ATTRPRIORITY=COLOR style like HTMLBlue or Pearl. In an ATTRPRIORITY=COLOR style, groups are not distinguished by line patterns, and the line patterns for second and subsequent groups match the line pattern for the first group.
