I've created a Pie chart in a sub-report (CR XI).  I think it has to be in a sub-report so I can suppress the chart and the accompanying table when there is no data.  When I add labels to the slices of pie it adds the "Sum of P1", "Sum of P2" etc seen on the Data tab of the Chart Expert.  I'd like to change the "Sum of P1" to what P1 represents in my data but can't figure out where I can manually input my data labels.  What am I missing?
