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 -------------
