If you are doing it in Excel right click the pie chart and select format and change the angle of the first slice. The macro for it looks like the following
Sub Macro1()

' Macro1 Macro

ActiveSheet.ChartObjects("Chart 1").Activate
ActiveChart.SeriesCollection(1).Select
With ActiveChart.ChartGroups(1)
.VaryByCategories = True
.FirstSliceAngle = 10
End With
'rotate it again to 20 degrees
With ActiveChart.ChartGroups(1)
.VaryByCategories = True
.FirstSliceAngle = 20
End With
End Sub
