RE: st: line graph with confidence interval
Note that -xtgraph- is a user-written program on SSC.
It does not support Stata 8 or Stata 9 graphics.
In addition, doing it yourself is an option. For
example, something like
egen meanvar = mean(var), by(year)
line meanvar year
gives you means against a time variable (in this
case -year-). Given upper and lower limits,
twoway line meanvar year || rcap upper lower year
gives you the intervals as well. And so forth.
