Assuming SAS/STAT 14.1 (SAS 9.4)

 

Add the PLOTS=Survival statement to your PROC PHREG statement to get a survival curve. Note that the survival curve will be for a specified age value, usually the average. You can choose to have a different value used if required, usually to make it easier to interpret or explain.

Do i also use the mean for categorical variable?or is it just for continious variables?Thanks for the comment.

Uh...you can't take an average of a categorical variable? Possibly an ordinal, but it wouldn't make logistical sense.

 

Use the Reference Category or a category of interest in this case. See what the documentation states as well.
