Svend is right. 
-catplot- on SSC was written as a generalisation of Svend's basic trick.
That is, it counts categories and then shows a graph of the category
counts. 
You needn't do it yourself.

i have data that look like this (portion of):
 
obs year ind_methd
1 2003 rapid
2 2005 standard
3 2004 emerg
4 2002 emerg
5 2002 emerg
6 2005 rapid
7 2006 rapid
8 2003 rapid
9 2006 standard
10 2005 rapid
11 2005 standard
12 2005 standard
13 2006 rapid
14 2002 rapid
 
i want to produce bar chart ala [G] p. 125, with year as x-axis and
count 
of ind_methd as y-axis. however i only wanted rapid and standard to be 
shown on the chart. i am just wondering what i need to do to ind_methd 
variable to make: graph bar (count) ind_methd, over(year) bargap(-30) 
to work to show the graph that i wanted to show.
 
------------------------------------------------
 
Something like:
 
   gen x=1
   graph bar (count) x if ind_methd != "emerg" , over(ind_methd)
over(year)
