line graph with year marks on line

[Christian Vienna]

Dear Forum,

I have time-series data and I want to plot two variables 'against' each other, so that the line displays the cyclical behaviour of the two variables over time.

The variables are:

hpr=real house prices
real thh (rthh) = real household debt

The graph below displays the relationship between hpr and rthh over time. What I would like to do, is to set time-markers on the line, at certain points (2008 f.e.)

The code for the graph looks like this (my data-set is technically panel data):

line hpr rthh if iso=="USA", title("USA")

Again, I would now like to 'mark' certain points on this line with the corresponding year. This also means, I do not want to mark each year of the time series, as this would be messy, but only certain years (1970, 1980, 1990, 2008).


Thank you very much,
Christian

You don't give a data example and your graph doesn't show properly. But this is code which anyone can run in Stata (unless behind some firewall) which shows some technique:

webuse grunfeld
line invest year if company == 1 || scatter invest year if company == 1 & year == 1945, ms(none) mla(year) mlabpos(6) legend(off)

For how to show data and graphs, see https://www.statalist.org/forums/help#stata

many thanks. This appears to me like a very nice code to play around with.

I attach some of my data, in case future statlists are interested.
