Re: st: Graph bar using the over option

[David Airey <david.airey@vanderbilt.edu>]

Mess around and you'll get it, for example, see:

clear
input time var_4 var_5 var_6
1 10 20 30
2 20 30 40
3 30 40 50
end

graph bar var_4-var_6, over(time)

reshape long var_, i(time) j(variable)
graph bar var_, over(time) over(variable)

clear
input time response var
1 10 4
2 20 4
3 30 4
1 20 5
2 30 5
3 40 5
1 30 6
2 40 6
3 50 6
end

graph bar response, over(time) over(var)
