Anyone know how to get a scatter plot to display a label containing a field value, rather than the default display of the X,Y values used to create the scatter plot?

For example, I've a table containing City, SalesPotential, and MarketShare. Plotting the SalesPotential and MarketShare produces a great matrix for allocating our sales resources. The rub is that the City name will only show up in the legend, not on a label next to the point.

Any ideas?
