The WPF doughnut chart is a circular graphic ideal for displaying proportional values in different categories. The doughnut chart in WPF supports animation and interactive features such as tooltip and selection.
Any view can be added to the center of the doughnut chart.
Explode a single segment of the WPF doughnut chart to differentiate it from others.
Group the smaller segments in the WPF doughnut chart into a single segment called “others”.
Customize the look and feel of the doughnut using the built-in APIs.
Customize the start angle and end angle of the chart to create a semi-donut chart.
Making the inner radius 0 will change the doughnut chart to a pie chart. You can customize both the radius and inner radius of the doughnut.
Arrange data labels smartly to avoid overlapping when the data point values are in a close range.
