How to change X axis in CIF plot (either in proc lifetest or proc phreg)?

[Reeza]

That's not the one you need so doesn't affect this question, but will affect future output. I would suggest seeing if a colleague/classmate has not and get it from them. They can change slightly between versions so providing mine wouldn't necessarily solve your issue.

Thanks  - I was playing with your old code before I knew what I was doing and I think I changed it already so I do not have the original template.

Hi Reeza,

I reset the template to default and changed ONLY the X axis ticks. I was able to change the X axis. However, I am getting these strange lines from the end of the curve (as shown below). This was happening to me before I changed the template too and I was wondering whether you have seen this before? I have pasted template below.

Proc template;
source Stat.Phreg.Graphics.CIF;
define statgraph Stat.PHReg.Graphics.Cif;
   dynamic title1 title2 title3 title4 xviewMin xviewMax group groupIndex groupName plotCL
      transparency _byline_ _bytitle_ _byfootnote_;
   BeginGraph;
      entrytitle TITLE1 TITLE3;
      entrytitle TITLE2 TITLE4 / textattrs=GRAPHVALUETEXT;
      layout overlay / xaxisopts=(linearopts=(viewmin=0 viewmax=5)) yaxisopts=(
         label="Probability");
         if (PLOTCL)
            bandplot LimitLower=LOWERCIF LimitUpper=UPPERCIF x=TIME / group=GROUP index=
               GROUPINDEX modelname="CIF" datatransparency=transparency;
         endif;
         stepplot y=CIF x=TIME / group=GROUP index=GROUPINDEX name="CIF";
         if (EXISTS(GROUP))
            discretelegend "CIF" / location=outside title=GROUPNAME;
         endif;
      endlayout;
      if (_BYTITLE_)
         entrytitle _BYLINE_ / textattrs=GRAPHVALUETEXT;
      else
         if (_BYFOOTNOTE_)
            entryfootnote halign=left _BYLINE_;
         endif;
      endif;
   EndGraph;
end;

It looks like the data is connecting itself back at 0 for some reason (the last data point is connecting back to the first). 

Try changing your stepplot to look like this:

stepplot y=eval(ifn(time<=5,CIF,.)) x=eval(ifn(time <=5,TIME,.)) / group=GROUP index=GROUPINDEX name="CIF";

[tbn1]

That does seem like that it is what is happening but that correction made the graph crazier somehow!

[JeffMeyers]

That is strange. How did it become crazier? I don't know what it does behind the scenes as I only know the dataset it makes when the procedure ends.

[Reeza]

That x axis label looks like code, or did you do that on purpose?

[tbn1]

That was what happened when I entered the change

I also wanted to ask if you are aware that the plots created by PHREG are predicted curves and not the actual observed data? LIFETEST will give CIF curves based on the observed data so I would stick with that. If you don't want to try my macro and don't want to keep messing with the template, why not just output the dataset (outCIF) and then do an SGPLOT or write your own template to make the curve you want? Are you trying to make the template have the same changes every time or are you modifying it to make a single graph?
