Hello Statalisters,

I use Stata 15 on Mac and would like to overlay two KM graphs, obtained using two stsset commands.

For example:
Code:
 use http://www.stata-press.com/data/r13/stan3, clear
stset t1, failure(died)
sts graph
stset t1, failure(died) origin(time 30) exit(time 500)
sts graph
I want to be able to overlay/superimpose the two KM curves on the same graph.

Is this possible?

Thank you so much, Horea
