The doughnut chart can be a pie plot such as the one shown in this figure.

Each point can be assigned a border, fill effect, and a detachment distance for the pie slice. Assigning null for a border or fill effect indicates that the property is null.

Each point can be assigned a border, fill effect, and a detachment distance for the pie slice. Detachment distance is measured relative to pie radius (0 = no detachment, 1 = detachment is length of pie radius). The detachment distance (PieDetachments property) is used to create an exploded doughnut chart.
