[Angela]

Hi Jim,

I tried it and it while it does make the diagram look more like what I want, there are a few categories still out of order.  Thank you for your help!

 Hi Angela,
 Assuming that your reformatted data is named
 "data", have you tried:

 data[order(data$count,data$before,decreasing=TRUE),]
