RE: st: Graph of two grouping variables

["Scholes, Shaun" <s.scholes@ucl.ac.uk>]

This sounds like something I was playing with a couple of weeks ago. I came up with the following to match one of the figures in a paper I was reading:

ID	year	cause1	cause2	cause3	cause4	cause5	cause6	cause7
1	1	150	25	28	31	13	7	77
2	2	125	38	28	38	12	3	55
3	3	129	38	38	27	26	16	71
4	4	134	35	47	28	20	19	68
5	5	103	39	31	24	27	21	68

label define yearlbl 1 "1981" 2 "1986" 3 "1991" 4 "1996" 5 "2001"
label values year yearlbl

graph bar (asis) cause1 cause2 cause3 cause4 cause5 cause6 cause7,stack over(year) ///
legend(order(1 "CHD" 2 "Lung" 3 "Cancer" 4 "Lungdis" 5 "Injury" 6 "Suicide" 7 "Other")) ///
ytitle("Title") ylabel(0 100 200 300 400,ang(hor)) bar(1,color(black)) bar(2,color(gray)) title("Males",pos(11))

I'm a novice with graphs...but this seemed ok for my purposes. So age group would replace 'year' in this example; and you would have 12 causes rather than 7.
Feel free to ignore: it may not be what you are looking for. Would be very interested, however, to know your final solution!

Then I would suggest to take hints from
