Not quite sure I get what you're trying to do, but maybe something like this:

--------- set up example dataset ----------
clear
set obs 1000
gen byte group=trunc(4*runiform())
gen byte died=rbinomial(1, group/5)
replace died=0 if group==0
-------------- end of setup ---------------

------------ result of above --------------
. tab group died

           |         died
     group |         0          1 |     Total
-----------+----------------------+----------
         0 |       215          0 |       215 
         1 |       216         52 |       268 
         2 |       159         95 |       254 
         3 |       102        161 |       263 
-----------+----------------------+----------
     Total |       692        308 |     1,000 
-------------------------------------------

------------- draw bar graph -------------
gen byte died7d=100*(died & group==1)
gen byte died30d=100*(died & group==2)
gen byte died180d=100*(died & group==3)
graph bar (mean) died7d died30d died180d, ascategory ///
	yvaroptions(relabel(1 "7 days" 2 "30 days" 3 "180 days")) ///
	ytitle("% mortality")
------------- end of example -------------
