Zooming can be performed in the Sunburst chart using ZoomBehavior class. To implement zooming, you need to create an object of the ZoomBehavior class available in the C1.Xamarin.Forms.Chart.Interaction namespace and pass it as a parameter to the Add method. This method adds zoom behavior to the behavior collection by accessing it through Behaviors property of the ChartBase class.

The image below shows how Sunburst appears on zooming.

The following code examples demonstrate how to implement zooming in C#. These examples use the sample created in the Quick Start section.

ZoomBehavior z = new ZoomBehavior();
sunburst.Behaviors.Add(z);

Similarly, panning can be implemented in the Sunburst chart by creating an object of TranslateBehavior class available in the C1.Xamarin.Forms.Chart.Interaction namespace and passing it as a parameter to the Add method. This method adds translation behavior to the behavior collection by accessing it through Behaviors property of the ChartBase class.

The image below shows how Sunburst appears on panning.

The following code examples demonstrate how to implement panning in C#. These examples use the sample created in the Quick Start section.

TranslateBehavior t = new TranslateBehavior();
sunburst.Behaviors.Add(t);
