Subject: st: RE: Re: About cumul command
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.
J. Cox
Q1/04 SJ 4(1):66--88 (no
commands)
a review of official and user-written commands for
graphing univariate distributions; includes tricks
beyond what is obviously and readily available
STB-51 gr41 . . . . . . . . . . . . . . . . . . Distribution function

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.
