Special Pie Chart Properties

Pie charts are quite different from the other chart types since they do not follow the concept of a two-dimensional grid or axes. Altering the diameter of the pie or the properties of the exploding slices can be accomplished with the properties of the Pie class.

Starting Angle

Use the PieOptions.StartingAngleAttached property to specify the angle at which the slices for the first series start. The default angle is 0 degrees. The angle represents the arc between the most clockwise edge of the first slice and the right horizontal radius of the pie, as measured in the counter-clockwise direction.

Exploding Pies

A slice of a Pie chart can be emphasized by exploding it, which extrudes the slice from the rest of the pie. Use the Offset property of the series to set the exploded slice's offset from the center of the pie. The offset is measured as a percentage of the radius of the pie.
