sts graph (by group and overall on same graph)

[Amrita Rao]

I'm trying to graph survival curves stratified by group and overall on the same plot. I'm able to create these graphs separately, but is there a way to overlay them?

sts graph
sts graph, by(site)

The trick of expanding the data and creating a total category should get you what you want.

use https://www.stata-press.com/data/r17/drug2, clear
set scheme s1color
sts graph, hazard saving(gr1, replace)
expand 2, g(new)
replace drug=3 if new
sts graph, by(drug) hazard legend(order(1 "placebo" 2 "drug" 3 "total")) saving(gr2, replace)
gr combine gr1.gph gr2.gph

This worked for me -- thank you so much!
