Matthias was looking for a spineplot, and Scott's code got close to
that, but is not a spineplot. The code below should give you a
spineplot (and a barplot and a combination of the two for comparison).
*---------------- begin example --------------------
sysuse auto,clear
collapse (count) mpg, by(rep foreign)
drop if rep78 >=.
reshape wide mpg, i(rep78) j(foreign)
graph bar (asis) mpg1 mpg0, ///
over(rep78) stack ///
legend(order(1 "foreign" 2 "domestic")) ///
title("bar plot") ///
bar(1, color(gs8)) bar(2,color(gs12)) ///
name(bar,replace)
sysuse auto, clear
collapse (count) mpg (mean) foreign, by(rep)
keep if rep !=.
sum mpg
gen freq = .95*mpg/r(sum)
sort rep78
gen gr_order = _n - 1
expand 2
bysort rep: gen t = _n
gen gap = gr_order * .05/4
gen sum = sum(fre) if t ==2
replace sum = sum[_n-1] if t == 1
replace sum = 0 in 1
replace sum = sum + gap
forvalues i = 0/4 {
local ibegin = `i' * 2 + 1
local iend = `i' * 2 + 2
local begin = sum[`ibegin']
local end = sum[`iend']
local mid = `begin' + (`end' - `begin')/2
local lab = rep78[`ibegin']
local xlab `"`xlab' `mid' "`lab'""'
}
gen foo = 1
twoway area foo sum if rep <=1, color(gs12) ///
|| area foreign sum if rep <=1, color(gs8) ///
|| area foo sum if rep <=2 & rep>1 , color(gs12) ///
