Subject | st: Scatter plot of single variable at different times |
Date | Wed, 07 Dec 2011 17:30:41 -0600 |
Hi Stata-listers!I have a panel data set in long format. I would like to make a scatter plot of a single variable observed at different time periods.
Below is a silly example. The example code below plots individuals' log wages in 1968 against log wages in 1969. But I would like to know if there is a "cleaner" way to do this. Is there a way that I could select two different time periods and arrive at such a scatter plot without having to manually -reshape- my data each time?
webuse nlswork, clear keep idcode year ln_wage reshape wide ln_wage, i(idcode) j(year) scatter ln_wage68 ln_wage69If there is anything built into Stata, or if there is any user-written ssc command that does exactly this, I would appreciate a hint in that direction.
Thanks! Christian Raschke * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
