How to create a graph covering the development of a variable over time including interquartile ranges?

[Tal Wa]

Dear all,

I would like to create a graph such as Altavilla et al. created it on page 8 (Figure 1): https://www.google.com/url?sa=t&rct=...gSVC6Jv4lM0tjX

I have all the data available, but I do not know which command I should give STATA to create such a graph (including the quartiles).

Many thanks for your help!
Best wishes,
Tal

We can't so easily give commands either without knowing your variable names. But this is a sketch:

Suppose you have a quarterly date variable qdate and some variable whatever to summarize.

foreach q in 5 16 25 50 75 84 95 {
     egen whatever`q' = pctile(whatever), p(`q') by(qdate)
}

twoway rarea q5 q95 qdate || rarea q16 q84 qdate || rarea q25 q75 qdate || line q50 qdate

where you will need add options to tune colours, and so forth. .

Many thanks Nick! Worked perfectly.

Next time I will provide var names
