There was a discussion on this a while back, see: http://tolstoy.newcastle.edu.au/R/e2/help/07/08/22858.html There is some good discussion there on why you may not want to do this (adding the numbers at the tops of bars tends to distort the visual comparison of heights, among other things). If you follow the thread for a while and think about what you really want to do, there are some examples of alternative ways to accomplish what you probably really want to do. -- Gregory (Greg) L.
