Re: st: added line in front of area shading

[Roger Harbord <roger.harbord@bristol.ac.uk>]

That's a possibility, but doesn't look as nice.
I had another look in the archives and found this:

http://www.stata.com/statalist/archive/2003-10/msg00502.html

- wherein Jeff Pitblado answers the same question raised by Michael Blasnik.

Jeff's solution is to use -twoway function- to add the line:

. twoway lfitci mpg headroom || function y=20, range(headroom) clcolor(fg)

In fact i searched on -rarea- and that message only came up because -rarea- is 
in the "next by date" message! Usually such behaviour appears to be a 
misfeature of the search facility but serendipity strikes...  Previously I 
searched on "added line" which didn't bring this message up either. Ideally 
I'd like to have been able to search on something like
"(added line OR yline OR xline ) AND (rarea OR lfitci)"

Anyone know if the search engine supports such operators?
(if it does the syntax is not that)

Roger.
