By the way, it doesn't appear that the wedges are being numbered counterclockwise. I created a chart with 8 wedges. The first five are numbered clockwise, whereas the remaining are numbered counterclockwise. To clarify, clicking clockwise around the pie chart displays rows in the following order: 0, 1, 2, 3, 4, 7, 6, 5.
