Shading between two lines in a graph

[Sigrid Vikjord]

Dear Statalist,

I'm trying to create a shaded area between the two borders of the confidence interval around TS_HUNT_lln (between lb_i and ub_i). Below is the code I'm using:

twoway (line hr_i lb_i ub_i TS_HUNT_lln, sort lp(l - -)) ///
 if inrange(TS_HUNT_lln, -10,7) , yscale(log) ytitle("Adjusted Hazard Ratio") ///
 xtitle("BMD T-score") ///
 plotregion(style(none)) ///
 yline(1) ///
 ylabel(0.5 1 1.5 2 3, angle(horiz) format(%4.3f)) ///
  legend(off) xlabel(-10(1)7)  name(or_age_mi, replace)

Could -twoway rarea- be used somehow?

 twoway  rarea lb_i ub_i TS_HUNT_lln if inrange(TS_HUNT_lln, -10,7), sort astyle(ci)  || ///
line hr_i TS_HUNT_lln if inrange(TS_HUNT_lln, -10,7) ///
  ,sort lp(l) yscale(log) ytitle("Adjusted Hazard Ratio") ///  xtitle("BMD T-score") ///
 plotregion(style(none)) ///
 yline(1) ///
 ylabel(0.5 1 1.5 2 3, angle(horiz) format(%4.3f)) ///
  legend(off) xlabel(-10(1)7)  name(or_age_mi, replace)

Thank you Maarten! That worked perfectly.
Do you know how I could bring the yline to front, overlaying the rest of the plot?

You can’t do that. Added lines are automatically laid down early. What you can do is add a call to twoway function laying down a line at 1 over the horizontal range of the graph.
