Doughnut Chart

Expanded Short Description

The Doughnut Chart is represented by the Doughnut3DSeriesView object, which belongs to Pie and Donut Series Views. This view is useful when it's necessary to compare the percentage values of different point arguments in the same series, and to illustrate these values as easy to understand pie slices, but with a hole in its center. In addition, the 3D look makes it possible to rotate a chart to position pie slices in an attractive and easy-to-understand way.

A Doughnut chart is shown in the image below.

Expanded Chart Type Characteristics

The table below lists the main characteristics of this chart type.

Feature Value
Series View type Doughnut3DSeriesView

Expanded Example

The following example demonstrates how to create a ChartControl with a series of the Doughnut3DSeriesView type, set its general properties, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.
