I don't think there is any direct way to do this in -sts graph-, but you can generate the survivor function, set up your own labels first and then add them onto -sts graph- with the -plot()- option. Something like this...
sysuse cancer, clear
stset studytime, f(died)
sts gen surv=s
local addplot "plot(scatteri"
forvalues x = 10(10)30 {
summ surv if studytime < `x', meanonly
local y = r(min)
local l = string(`y',"%5.3f")
local addplot `"`addplot' `y' `x' "`l'""'
}
local addplot `"`addplot', ms(i) mlabp(12))"'
sts graph, `addplot' legend(off)
Hope this helps

Hi all,
I want to see the K-M graph with the y-axis values at some
points in the survival function. For instance, see the
exact y-values of the Survival function at X-axis values
like 10, 20, 30 days. I need these values be showed in the
graph, near the line of the survival function.
How can I do it?
Thanks,
Patricia
