How to add the percentiles to line graph

[Olivia Li]

Hi good morning !
I'v got a problem of replicating a graph.
The horizontal axis 1-8 means each occupation group.
The vertical axis means the average salary of each group.
I don't know how to add the 95% percentile and 5% percentile to this graph.
It would be so nice if you could help me with this !!

sysuse nlsw88, clear
drop if grade < 10 | grade == .

collapse (mean) wage_mean = wage ///
         (p5) p5 = wage (p95) p95 = wage, by(grade)

twoway (rcap p5 p95 grade) ///
       (connected wage_mean grade)
