Dear Anant Will this do the trick... ****************************************** * CREATE FAKE DATASET clear set obs 10 generate year = 1995 + _n expand 4 sort year generate cohort = mod((_n-1),4)+1 tab year cohort expand 100 generate tax = int(uniform()*5)+1 tab tax recode tax (1 2=1 "1 or 2") (3 4 5=0 "3,4,5"), gen(rtax) tab tax rtax ****************************************** * Start of real code * collapse to get proportions collapse rtax , by(cohort year) * Convert to percentage replace rtax = rtax*100 * separate into four variables by cohort separate rtax, by(cohort) * graph it graph twoway (line rtax1 rtax2 rtax3 rtax4 year), /// xlabel(1996(1)2005, angle(45)) ///legend(label(1 "Cohort 1") label(2 "Cohort 2") label(3 "Cohort 3") label(4 "Cohort 4"))
And here is the graph that it creates http://screencast.com/t/Y2FkZGQ0Y2U Hope that helps, Michael N. Mitchell See the Stata tidbit of the week at... http://www.MichaelNormanMitchell.com On 2010-04-18 8.06 PM, Thaker, Anant wrote:
I am a Stata 11/SE user. In my dataset, I have a cohort variable coded 1-4 with the various subgroups (e.g. 1 =<1934, 2 = 1934-1948, etc.), and an ordered variable that shows views on progressive taxation (coded 1-5 in terms of relative support). These data points are spread over a number of years (from the General Social Survey). I'm trying to chart out the % of respondents who selected 1 or 2 on the taxation variable, by cohort subgroup, over time. So the x-axis would be year, the y-axis would be "% who chose 1 or 2," and there would be four line graph series (one for each cohort subgroup). Would really appreciate some help! I can clarify as needed. Thanks! Note: data is currently coded as this example: YEAR COHORT TAXATION 2008 1965 1 YEAR COHORT TAXATION 1996 1975 3 ...
