In principle you count the number of observations and then put it
somewhere:
. sysuse auto
(1978 Automobile Data)
. count if foreign
22
. histogram mpg if foreign, subtitle(`r(N)' observations)
(bin=4, start=14, width=6.75)
However, watch out for missings. A more careful count is
. count if mpg < . & foreign
as the -histogram- will not show missings.
See also the -goldbar- code posted yesterday in reply to Richard
Goldstein for some technique.

I am starting to use graphs. So, I hope that you will forgive my
probably basic question.
I run the following command:
histogram ib_scaled_w if ib_scaled_w >-.1 & ib_scaled_w<.1 &
country=="AUS" & sample_sum==1, bin(20) by(post_ifrs) title("AUS")
saving (hist_AUS, replace)
post_ifrs is a binary variable (coded 0 or 1).
Is there a way to display the total number of observations corresponding
to each of the histograms obtained with the command? (one graph with
post_ifrs = 0 and one graph with post_ifrs=1)
I searched in the Graphics Stata manual but did not find the solution.
