make a simple two way graph
note: we will discuss this command, and making graphs in general, in detail in lab4. You do not need to memorize this command until lab4.
see help scatter
examples:
scatter x y
scatter wage_re fem [w=n], ti("Occupational Wages by Proportion Female") note("Source:CPS 2005") saving(l1, replace)
twoway (scatter wage_re fem [w=n]) (line hat fem), ti("Occupational Wages by Proportion Female") note("Source:CPS 2005") saving(l1, replace)
* twoway (scatter wage_re fem [w=n]) (lowess wage_re fem), ti("Occupational Wages by Proportion Female") note("Source:CPS 2005") saving(l1, replace)
in lab2:
scatter twoway c a, c(m) by(b) saving(graph-name, replace)
** explain the c() and by() options
in lab5:
twoway (scatter wage fem, msymbol(oh)) (lfit wage fem) (lowess wage fem, /// bwidth(.4)), saving(lab4c, replace)
twoway (scatter wage edyrs, msymbol(oh)) (lfit wage edyrs) (lowess wage edyrs, /// bwidth(.4)), saving(lab4d, replace)
twoway (scatter wage union, msymbol(oh)) (lfit wage union) (lowess wage union, /// bwidth(.4)), saving(lab4e, replace)
graph combine lab4c.gph lab4d.gph lab4e.gph, saving(lab4f, replace) ///
ti("descriptive analysis of occupational wages") note("source: CPS 2005")
