including a legend with labels in an overlay graph

[Julian Schaper]

Dear all,

I would like to add to an overlay plot a legend, that gives for every color used the name of the region. Here I got 3 regions, that are already labeled, but for some reason the code below only produces a legend showing mean_var three times. What am I doing wrong?

graph twoway line mean_var year if year<2020 & region==1 || line mean_var year if year<2020 & region==2 || line mean_var year if year<2020 & region==3

Best,
Julian

I produced mean_var using:

bysort year region: egen mean_var=mean(var) if var!=.

Nevermind. I solved it myself using the following option:

legend(order(1 "Eastern Europe and post Soviet Union" 2 "Latin America" 3 "North Africa and the Middle East"))

If the values of region are labeled, this would produce a similar result that is more robust than using legend(order(...)):

xtset region year
xtline mean_var if year<2020, overlay
