Migrate from Xamarin.Forms SfSunburstChart to .NET MAUI SfSunburstChart

30 Oct 202413 minutes to read

The SfSunburstChart was created from the scratch using the upgraded APIs and performance of the .NET MAUI graphics library and framework layouts. However, to maintain the consistency of the API naming in MAUI SfSunburstChart, we renamed some of the APIs. The APIs changed in MAUI SfSunburstChart from Xamarin SfSunburstChart are detailed as follows:

Namespaces

Xamarin .NET MAUI
Syncfusion.SfSunburstChart.XForms
Syncfusion.Maui.SunburstChart

To make the migration easier, the most of the APIs from the Xamarin SfSunburstChart were kept in the .NET MAUI SfSunburstChart. Currently, most of the features have been added in the SfSunburstChart, but only a few are pending in the .NET MAUI along with some limitations. Please refer to the following details and the API migration information available below.

Initialize control

To initialize the control, import the sunburst chart namespace and Initialize SfSunburstChart as shown in the following code sample.

Xamarin 
<ContentPage
    . . .
    xmlns:sunburst="clr-namespace:Syncfusion.SfSunburstChart.XForms;assembly=Syncfusion.SfSunburstChart.XForms">

    <sunburst:SfSunburstChart/>

</ContentPage>
using Syncfusion.SfSunburstChart.XForms;
...

SfSunburstChart sunburstChart = new SfSunburstChart(); 
this.Content = sunburstChart;
.NET MAUI 
<ContentPage
    . . .    
    xmlns:sunburst="clr-namespace:Syncfusion.Maui.SunburstChart;assembly=Syncfusion.Maui.SunburstChart">

    <sunburst:SfSunburstChart/>

</ContentPage>
using Syncfusion.Maui.SunburstChart;
. . .
SfSunburstChart sunburstChart = new SfSunburstChart(); 
this.Content = sunburstChart;

API Migration

The following table illustrates the API migration for the sunburst chart.

SunburstChart

The following code example explains how to migrate Xamarin SfSunburstChart to the .NET MAUI SfSunburstChart.

Xamarin

    <sunburst:SfSunburstChart ItemsSource="{Binding DataSource}"
                              ValueMemberPath="EmployeesCount">
        <sunburst:SfSunburstChart.Levels>
            <sunburst:SunburstHierarchicalLevel GroupMemberPath="Country"/>
            <sunburst:SunburstHierarchicalLevel GroupMemberPath="JobDescription"/>

using Syncfusion.Maui.SunburstChart;

SfSunburstChart sunburstChart = new SfSunburstChart();

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;

Legend

Xamarin .NET MAUI

The following code example shows how to enable legend in the sunburst chart.

Xamarin 
<ContentPage
    . . .
    xmlns:sunburst="clr-namespace:Syncfusion.SfSunburstChart.XForms;assembly=Syncfusion.SfSunburstChart.XForms">

    <sunburst:SfSunburstChart.Legend>
        <sunburst:SunburstChartLegend x:Name="legend" 
                                      IsVisible="True"  
                                      LegendPosition="Left" >
        </sunburst:SunburstChartLegend>
    </sunburst:SfSunburstChart.Legend>
    . . .
</ContentPage>
using Syncfusion.SfSunburstChart.XForms;
...
SfSunburstChart sunburstChart = new SfSunburstChart();

SunburstChartLegend legend = new SunburstChartLegend();
legend.IsVisible = true;
legend.LegendPosition = SunburstDockPosition.Left;
sunburstChart.Legend = legend;

this.Content = sunburstChart;
.NET MAUI 
<ContentPage
    . . .
    xmlns:sunburst="clr-namespace:Syncfusion.Maui.SunburstChart;assembly=Syncfusion.Maui.SunburstChart" >

    <sunburst:SfSunburstChart.Legend>
        <sunburst:SunburstLegend Placement="Top" IsVisible="True"/>
    </sunburst:SfSunburstChart.Legend>

</ContentPage>
using Syncfusion.Maui.SunburstChart;

SfSunburstChart sunburstChart = new SfSunburstChart();

sunburstChart.Legend = new SunburstLegend()
{
    Placement = LegendPlacement.Top,
    IsVisible = true
};

this.Content = sunburstChart;

Data Label

To enable data labels, use the ShowLabel property in the SunburstChartDataLabel class and the ShowLabels property in the SfSunburstChart class, in Xamarin and MAUI respectively.
To customize the data label appearance, create an instance of the SunburstDataLabelSettings class and add it to the DataLabelSettings of SfSunburstChart. The following code explains how to initialize data labels.

Xamarin 
<ContentPage
    . . .
    xmlns:sunburst="clr-namespace:Syncfusion.SfSunburstChart.XForms;assembly=Syncfusion.SfSunburstChart.XForms">

    <sunburst:SfSunburstChart.DataLabel>
        <sunburst:SunburstChartDataLabel ShowLabel="True" FontAttributes="Bold" 
                                         FontSize="10" TextColor="Red" >
        </sunburst:SunburstChartDataLabel>
    </sunburst:SfSunburstChart.DataLabel>

</ContentPage>
using Syncfusion.SfSunburstChart.XForms;
...
SfSunburstChart sunburstChart = new SfSunburstChart();
SunburstChartDataLabel label = new SunburstChartDataLabel();
label.ShowLabel = true;
label.TextColor = Color.Red;
label.FontSize = 10;
label.FontAttributes = FontAttributes.Bold;
label.FontFamily = "ArialMT";
sunburstChart.DataLabel = label;

this.Content = sunburstChart;
.NET MAUI 
<ContentPage
    . . .
    xmlns:sunburst="clr-namespace:Syncfusion.Maui.SunburstChart;assembly=Syncfusion.Maui.SunburstChart" >

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

        <sunburst:SfSunburstChart.DataLabelSettings>
                <sunburst:SunburstDataLabelSettings FontSize="13" FontAttributes="Italic"
                                                    RotationMode="Angle" OverFlowMode="Trim" />
            </sunburst:SfSunburstChart.DataLabelSettings>

        <sunburst:SfSunburstChart.Levels>
            <sunburst:SunburstHierarchicalLevel GroupMemberPath="Country"/>
            <sunburst:SunburstHierarchicalLevel GroupMemberPath="JobDescription"/>
            <sunburst:SunburstHierarchicalLevel GroupMemberPath="JobGroup"/>
            <sunburst:SunburstHierarchicalLevel GroupMemberPath="JobRole"/>
        </sunburst:SfSunburstChart.Levels>
    </sunburst:SfSunburstChart>

</ContentPage>
using Syncfusion.Maui.SunburstChart;

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

To enable the tooltip, use the ShowTooltip property in the SunburstTooltipSettings class and the EnableTooltip property in the SfSunburstChart class, in Xamarin and MAUI respectively.
To customize the tooltip appearance, create an instance of the SunburstTooltipSettings class and add it to the TooltipSettings of SfSunburstChart.
