I do have to ask the graph snob question: Why a pie chart? There are almost always better optons that are perceived more accurately by readers, use less space, etc.

Good morning,

I have, what should be, a simple graphing problem.  I clustered doctors 
into four groups.  I created a table showing the proportion of doctors 
in each group who use a certain drug with their patients.  The 
proportions are simply the weighted means of a binary variable which 
indicates whether or not the drug is prescribed by that doctor.  Now I 
want to draw a pie chart showing those proportions.  I can easily draw a 
pie that displays proportions which are not weighted, but how do I tell 
Stata to draw the pie using the weighted means?  In short, I want the 
table and pie slices to be identical so I can give my client both.

Incidentally, how do I get the pie slice labels to be outside the pie 
and have the percentages next to the slice label?  It seems that 
everything goes inside the pie and we can either get labels or 
percentages, but not both.

Thanks,

Walt
