Hi,
I'm working with Stata 7 with data from a group of variables that I'm
processing through a loop and generating process-control charts. Stata 7
produces faster if less elegant graphs than Stata 8. The problem is that
I'm generating a new variable `UBAR' and putting a label on my graph with
rlab:
foreach j in 1 2 3 5 12 16 17 {
tempvar U TOT_CASES TOT_POPN UBAR 3UCL 2UCL
...
sort loc stata_week_end ***sort by location and stata date
for week ending on this date
quietly by loc: gen U = jcs`j' / total_popn *100
quietly by loc: egen TOT_CASES = sum( jcs`j')
quietly by loc: egen TOT_POPN = sum(total_popn)
quietly by loc: gen UBAR = `TOT_CASES'[_N]/`TOT_POPN'[_N] *
100
local ubar = `UBAR'
...
#delimiter ;
graph twoway `U' `UBAR' `3UCL' `2UCL' stata_week_end
...rlab(`ubar')
The problem is that the label and the graph of UBAR aren't matching and it
appears that the variable is carrying over from previous loops. Is there a
way to expunge the values at the close of the loop? "drop" doesn't work
with locals.
