Value on data points is duplicated on each dimension

[Anonymous]

This chart has three dimensions; Upgrades, renewals and upgrade % of total sales.  The upgrade % of total sales is a "value on data point".  How can I show upgrade % just once, instead of on each dimension?  Another thought was to change the font color to green, so that it only shows on the yellow dimensions.  Couldn't figure out how to change the font color.   Any suggestions would be greatly appreciated.

Thanks!

Correction, it has three expressions and only one dimension which is year.
