The Xamarin.Forms doughnut chart is a circular graphic, which is ideal for displaying proportional values in different categories. Doughnut chart 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 in the doughnut chart to differentiate it from others.
Group the smaller segments in the doughnut chart to a single segment called “others”.
You can customize the inner radius of the chart to make it pleasing. Making inner radius to 0 will change the doughnut to pie chart. You can customize both the radius and inner radius of the doughnut.
Customize the look and feel of the doughnut using built-in APIs.
Customize the start and end angle of the chart to achieve the semi-pie.
Arranges data labels smartly to avoid overlapping when the data point values fall in close range.
Easily get started with the Xamarin Doughnut Chart using a few simple lines of C# code example as demonstrated below,
