how do I restrict xtline height?

[Elijah Moreno]

Hey, I am using the command xline to generate these two red lines. I don't know how to make the height of the line stay within the confines of the graph region. 40 on the left is the highest value on the y-axis. I have seem something like "noextend" but not sure how to incorporate that code or if there are other solutions.

I must be missing something because I don't see how scatteri would help in this case. It looked helpful for scattering labels through out the graph but I didn't see anything connected to reducing the height of an existing line. I know that tline or xtline can both generate a line at a specified point but I don't know how to make the out stay within the bounds of the graph. Sorry if I missed something with this comment..

The help flags what you need: (I've corrected an obvious typo below):

Programmers: Note carefully scatteri's advanced_option recast(); see [G-3] advanced_options. It can
be used to good effect, such as using scatteri to add areas, bars, spikes, and dropped lines.

Here is an example you can run:

webuse grunfeld , clear
xtline invest , overlay ysc(log) yla(1000 100 10 1, ang(h)) legend(off) addplot(scatter invest year if year == 1954, ms(none) mla(company) mlabcolor(black) || scatteri 1 1939 1000 1939, recast(line))
