You can use Rob Bovey's XY Chart Labeler to do this.

Sorry if this is a repeated request, but I'm trying to show the distribution
of 16 points (labelled A through P) using X-Y coordinates. When I turn on
labels, I can show either the X-positions (label) or Y-positions (value), but
I really want to show the text name "A" through "P". Can this be automated
in Excel?
Thanks for any advice.
