There are commands to do this, which I presume is what you want. In
official Stata it is not too difficult. First read in suitable data
. sysuse auto
(1978 Automobile Data)

Suppose that -foreign- were a string variable, which we can simulate
with
. decode foreign, gen(Foreign)

Now go
. gen one = 1

. graph hbar (sum) one, over(Foreign) ytitle(frequency)

However, the user-written command -catplot- from SSC may prove more
convenient.
. catplot hbar Foreign

For -hbar- read also -bar-, for vertical versions usually more difficult
to read. Nick n.j.cox@durham.ac.uk

is there an option in stata to draw bar charts of string variables, i.e.

if the variable contains 40 "yes" and 60 "no", to draw a chart with two bars of height 40 and 60?

to put it differently, is there an option to visualize the results of the command tab varname
