Is there any way in Proc lifetest where I can change the range in horizontal axis instead of getting the default output? e.g. something like using haxis in proc gplot, where I may get the desired output.
I don't know much about PROC LIFETEST, but there is a Tech Support note that seems to contain a lot of info on customizing PROC LIFETEST graphs or reproducing them with PROC GPLOT (which does have a lot of customization ability).
In addition, PROC LIFETEST is one of the procs that supports ODS GRAPHICS (which is still experimental in SAS 9.1.3 -- if you want to adjust the axis for ODS GRAPHICS output, then you might want to contact Tech Support for help in that regard.
here's an example of how you'd use PROC LIFETEST with ODS GRAPHICS:
