Modifying x-axis range in PROC LIFETEST

Kels123 — Fri, 10 Mar 2017 23:57:26 GMT

Hello,

I have written a code to plot a survival curve using PROC LIFETEST:

proc lifetest data=clean.DATABASE3 plots=survival

(FAILURE atrisk (atrisktick maxlen=13 outside)=0 14 30 90 180 365) ;

time time1_C*censor1_C(1) ;

run; quit;

Because I want to better visualize my time points of particular interest, which are before the 365-day mark, I want to modify my x-axis to end at 365 days. However, I don't know how to do this. I tried using the overlay statement, but I don't think I understand how it is supposed to be used:

proc template;

layout overlay / xaxisopts=(shortlabel=XNAME

offsetmin=.05

linearopts=(viewmax=365 tickvaluelist=XTICKVALS

tickvaluefitpolicy=XTICKVALFITPOL);

endlayout; run;

Please help. I just wanted to know the simplest way to modify the x-axis when using PROC LIFETEST.

Thanks in advance.

Is that all of your proc template code?

Does this help:

Or the newest documentation:

Hello,

Try these xaxisopts and let me know please:

xaxisopts=(shortlabel=XNAME

offsetmin=.05

linearopts=(viewmax=365 TICKVALUESEQUENCE=(start = 1 end = 365 increment = 91) ));

This may also work:

xaxisopts=(shortlabel=XNAME

offsetmin=.05

linearopts=(viewmax=370 tickvaluelist=(0 14 30 90 180 365) ));

Many thanks,
