st: RE: overlaying 2 or more ciplot/option nolconfidence?
I take this as a reference to the user-written
program -ciplot- on SSC.
I am not quite clear what the precise problem
-ciplot- is best thought of as a wrapper
for -ci-. It has a -by()- option, just
as -ci- does, and the design decision
was to allow several confidence intervals
to be shown in one plot.
That _isn't_ how -twoway ... , by()-
works; in other words, -ciplot- follows
-ci-, not -twoway-, in what -by()- means.
-ciplot- has a -plot()- option, which is
more evident from looking at the code
than from looking at the help, but
I don't think that helps with what
I guess you want.
Perhaps what you want can be
done by saving individual graphs
and then combining.
As the whole point of -ciplot- is to draw
confidence intervals, I am somewhat bemused
by the option suggested. If you want
just to plot means, there are lots of ways
to do that.
