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

[ATTACH=CONFIG]temp_14202_1556102774188_87[/ATTACH]

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
