Using the same example,
sysuse citytemp, clear
distplot tempjan tempjuly, lc(blue navy)
gets you there pretty directly. There is no need to restructure the data
or to figure out the basic graphics.
You do need to install -distplot-, which is user-written:
SJ-5-3 gr41_3 . . . . . . . . . . . . . . . . . Software update for
distplot
(help distplot if installed) . . . . . . . . . . . . . . . N.

Q3/05 SJ 5(3):471
simplified syntax; both by() and over() are now allowed
There are broader discussions, all freely accessible, at
SJ-4-1 gr0003 . . . . . . . . . . . . Speaking Stata: Graphing
distributions
. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . N.

Q1/04 SJ 4(1):66--88 (no

plots the cumulative distribution function or survival function
and allows multiple variables
Starting from Jeetendra's starting point, something like
distplot yield, over(caste)
seems indicated.
