I am not sure whether the value of the by var is accessible with -by- so I
am using -graph combine- here
*******
sysuse auto, clear
g year=cond(runiform()<0.3,1978, cond(runiform()<0.6,1979,1980))
levelsof year, loc(levels)
foreach year of loc levels{
hist mpg, graphregion(color(white)) freq title("This is for year `year'")
name(hist`year', replace) nodraw
}
graph combine hist1978 hist1979 hist1980, plotregion(ifcolor(white))

Subject: st: help with a histogram by year
Dear members,
I am trying to get a histogram by year. I use the following command
hist y, by(year,graphregion(color(white))) freq
Two things annoy me so far.
1. I do not know how to get rid of the note on the lower left part of
the graph "Graphs by year". I tried adding
note(`" "')
at the end of the command, with no effect
2. I would like to add a small title under each graph for each year,
such as "For year 1990", "For year 1991", so that I could replace the
title added by stata automatically on the top of each graph, like
"1990", "1991".
Any suggestions would be greatly appreciated.
Thanks!
Sincerely,
Faye
