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.

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
