I think you need to loop over countries and then use -graph combine-.
Here is a code sketch:
egen country2 = group(country)
sum country2, meanonly
forval i = 1/`r(mean)' {
xtline response time if country2 == `i' , overlay name(gr`i')
local graphs `graphs' gr`i'
}
graph combine `graphs'

I have a panel of European regions over time. I would like to plot a
variable
against time for these regions grouped by countries - that is, I would
like to
have all the regions of one country in one plot, and the plots of all
countries
together on the same overall graph.
I can create one single graph containing all regions of a particular
country by
using "xtline ... , overlay" and specifying all regions of that country
using
the "if" option. But I have not found a way to get all the
country-specific
plots together on one graph.
I've tried "addplot xtline" which does not work. Also, the "by" option
is not
allowed, so that I cannot define a variable "country" which assigns the
same
number to all regions of a country, and then run "xtline ...,
by(country)".
