I would like to count and plot the number of patients addmitted to each
hospital, sorted by volume group.  Patients (variable name key, n=31818
observations) are assigned a numbered ID ranging from 20000-40000. 
Hospitals (variable name hospid, n=2000) are also assigned a numbered ID
ranging from 2000-5000.  Each hospid likely has many key observations
associated with it.  But when I plot it the program plots it based on the
numbered ID, instead of a unique values ie. 1-2000.  Any thoughts on what
commands to use and how to plot this?
