In the attached Excel workbook, I’ve created a Pivot Chart.

I keep on losing the percentages that sit on top of the bar charts, every time I change the filter on the service pivot

Is it possible to maintain them for each individual service, so their percentages are as clear as possible?

Howdy. If I understand correctly, you can right-click the chart and choose Chart Options. Choose Data Labels, and click on Value. However, if you don't show all Services, it will always show 100% for the individual Service selection.
