alternatively to Martin's approach you could write your titles of the 
subgraphs in the value labels of the by-variable:

sysuse auto, clear
gen year = cond(runiform()<0.3,1978, cond(runiform()<0.6,1979,1980))
label define yearlab 1978 "For year 1978" 1979 "For year 1979" 1980 "For 
year 1980", modify
label values year yearlab
histogram price, by(year, note(""))

best, rich

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.
