Pie Chart has a red line along the edge of some sectors.

In some scenarios, a Pie Chart will show a thin red line along the edge of the pie for some sectors even though nothing is marked. This is as designed. A red line along the edge of a sector indicates a negative value for that sector. As shown in the attached screen shot (Filename: "RedLine_Pie.png"), the Pie Chart sectors for "Jon" and "Watson" have a red line because they have negative values for the "Age" column.
