Remarks

The Sunburst chart control ensures a well-defined hierarchical structure of the data and effectively communicates relationships between different levels of information.

SfSunburstChart class properties provide an option to add the levels collection, allowing customization of the chart elements such as legend, data label, center view, and tooltip features.

Levels

Levels are used to visualize different layers or depths in a hierarchy, aiding in the visualization of structured data. SfSunburstChart offers Levels property.

To add the levels, create an instance of the required SunburstHierarchicalLevel class, and add it to the GroupMemberPath property.

Legend

The Legend includes data points from the first-level items. The information provided in each legend item helps identify the corresponding sunburst sub levels. The Levels of GroupMemberPath property value will be displayed in the legend item.

To render a legend, create an instance of SunburstLegendand assign it to the Legend property.

</sunburst:SfSunburstChart>

 SfSunburstChart sunburstChart = new SfSunburstChart();

 sunburstChart.Legend = new SunburstLegend();

 sunburstChart.SetBinding(SfSunburstChart.ItemsSourceProperty, "DataSource");
 sunburstChart.ValueMemberPath = "EmployeesCount";

 sunburstChart.Levels.Add(new SunburstHierarchicalLevel() { GroupMemberPath = "JobGroup" });
 sunburstChart.Levels.Add(new SunburstHierarchicalLevel() { GroupMemberPath = "JobRole" });

 this.Content = sunburstChart;

Data Label

Data labels are used to display values related to a sunburst chart segment. To render the data labels, you need to enable the ShowLabels property as true in SfSunburstChart class.

To customize the sunburst chart data labels rotation mode using SunburstLabelRotationMode and its default value is Angle, overflow mode using SunburstLabelOverflowMode and its default value is Hide, and label styles, you need to create an instance of SunburstDataLabelSettings and set it to the DataLabelSettings property.

<sunburst:SfSunburstChart  ItemsSource="{Binding DataSource}" 
             ShowLabels="True"   ValueMemberPath="EmployeesCount">

 sunburstChart.ShowLabels = true;
 sunburstChart.DataLabelSettings = new SunburstDataLabelSettings()
 {
       OverFlowMode = SunburstLabelOverflowMode.Trim,
       RotationMode = SunburstLabelRotationMode.Angle,
       FontAttributes = FontAttributes.Italic,
       FontSize = 13
 };
 sunburstChart.SetBinding(SfSunburstChart.ItemsSourceProperty, "DataSource");
 sunburstChart.ValueMemberPath = "EmployeesCount";
 sunburstChart.Levels.Add(new SunburstHierarchicalLevel() { GroupMemberPath = "Country" });
 sunburstChart.Levels.Add(new SunburstHierarchicalLevel() { GroupMemberPath = "JobDescription" });
 sunburstChart.Levels.Add(new SunburstHierarchicalLevel() { GroupMemberPath = "JobGroup" });
 sunburstChart.Levels.Add(new SunburstHierarchicalLevel() { GroupMemberPath = "JobRole" });

 this.Content = sunburstChart;

Tooltip

Tooltip displays information while tapping or mouse hovering on the segment. To display the tooltip on the sunburst chart, you need to set the EnableTooltip property as true in SfSunburstChart.

To customize the appearance of the tooltip elements like Background, TextColor, and Font, create an instance of the SunburstTooltipSettings class, modify the values, and assign it to the TooltipSettings property in SfSunburstChart.

MainPage.xaml

<sunburst:SfSunburstChart  ItemsSource="{Binding DataSource}" 
             EnableTooltip="True"   ValueMemberPath="EmployeesCount">

  <sunburst:SfSunburstChart.BindingContext>

CenterView

Center is used to share additional information about the sunburst chart. The binding context of the Centerview will be the respective sunburst. To display the center view on the sunburst chart, you need to set theCenterView property in SfSunburstChart.

CenterHoleSize is used to prevent overlapping with segments in the sunburst center view.
