To put the % value on each pie chart slice do this (as shown here):

1. On the design surface, right-click on the pie and select Show Data Labels. The data labels should appear within each slice on the pie chart.
2. On the design surface, right-click on the labels and select Series Label Properties. The Series Label Properties dialog box appears.
