Hi,

You can use this free add-in to link data label content to cells.
http://www.appspro.com/Utilities/ChartLabeler.htm

In those cells you calculate the value you need to display.

Cheers
Andy

I've created a chart with several 100% stacked columns, each having multiple
data points in common. I'd like to show what percentage each of the data
points is in relation to its column but the percentage data label is greyed
out. Is there another way to do what I'm trying?

Thanks!
