## st: RE: graph bar: frequencies as a label

Yes; I know how to do this.

The Visual Guide is an excellent resource on official Stata graphics. But -- correct me if I'm wrong -- it doesn't touch on user-written programs. So, the usual route to follow is

. findit bar

which gives lots of pointers including

SJ-4-2 gr0004 . Speaking Stata: Graphing categorical and compositional data Q2/04 SJ 4(2):190--215 (no commands) discusses graphical possibilities for categorical and compositional data

catplot from http://fmwww.bc.edu/RePEc/bocode/c 'CATPLOT': module for plots of frequencies, fractions or percents of categorical data / catplot shows frequencies (or optionally fractions or percents) / of the categories of one, two or three categorical variables.

In your case, -price- is irrelevant, as you want a simple bar chart of the frequencies of a variable. Installing -catplot- gives you one way

. ssc inst catplot . catplot bar headroom, percent blabel(bar, format(%5.2f))

But you can get there with official Stata too

except that tweaking the format eludes me for the moment.

This may be covered in Michael Mitchell's book, but I can't check. Colleagues grabbed my copy of the book gleefully as soon as they spotted it and it's hardly been in my hands since the day it arrived.
