How do I change the Y axis on proc lifetest?

I am using proc lifetest to create survival plots. I want to change the minimum on the y-axis from 0 to, say, 0.5. I have not had success following the SAS documentation and I am not well versed in proc template. I have tried running this proc template and then running my lifetest code but I do not quite understand how to get this template "into" the lifetest procedure.

 

Can someone please advise?? Thank you!

 

proc template;

 define statgraph Stat.Lifetest.Graphics.ProductLimitSurvival; 
  begingraph;
   layout overlay /
    yaxisopts=(label="Incidence of DM" linearopts=(viewmin=0.5 viewmax=1 tickvaluelist=(0.5 0.6 0.7 0.8 0.9 1.0)));
   endlayout;
  endgraph;
 end;
run;

 

ods graphics on;
proc lifetest data=dm_analysis  method=lt plots=survival intervals=1 to 10 by 1;
 time dm_survt_yr*diabetes(0);
 strata M_cohort;
 where casecon in (0,1) and prev_diabetes=0 and dm_survt_flag=0 and age_20150101 ge 18; 
run;
ods graphics off;

If you submit this statement:

 

ods path show;

 

What does it say in your log?

Following that statement, the log is:

 

6900  ods path show;
Current ODS PATH list is:

1. SASUSER.TEMPLAT(UPDATE)
2. SASHELP.TMPLMST(READ)

Re: How do I change the Y axis on proc lifetest?

First, set ODS TRACE ON; and run PROC LIFETEST with the plot you want.  This will list the template(s) used in the log.  Then, source the template to a .sas file, and open it in the program Editor.  This will show you the GTL code.  Add the proc template; run; around the template code.  

 

Now, change the yaxis viewmin=0.5 in both places in the code.  Compile the template which will save it to your sasuser.templat itemstore.  Now, rerun proc lifetest, and it should use this new template from sasuser for all subsequent runs of proc lifetese.  When you no longer want this modified template, delete it from sasuser (but not from sashelp).

 

Here is the modified output.  Note y-axis.
