Customize vertical axis/survival probability in PROC LIFETEST

haoduonge — Fri, 18 Jun 2021 20:04:43 GMT

Hi all,

I see many posts on how to customize the KM graph.

However, I just need the basic one and would like to ask if we can customize the vertical axis within PROC LIFETEST?

The codes below will give me a full graph of the survival probability from 0 to 1.

Is there anyway to limit it to 0.8 to 1? That will zoom out the graph.

Thank you!

Have you tried changing the viewmin/viewmax values or the tickvalue list as illustrated in this example from the documentation?

https://documentation.sas.com/doc/en/pgmsascdc/v_010/statug/statug_kaplan_sect018.htm

Basically you just need to add the following before your code:

%ProvideSurvivalMacros;
%let yOptions = label="Survival"
                linearopts=(viewmin=0.8 viewmax=1
                            tickvaluelist=(0.8 .9 1));

%CompileSurvivalTemplates;

It is so strange, I add that before my codes and the figure does not change a bit.
