The center view of the doughnut chart is used to share additional information about it. Any view can be added to the doughnut chart center using the CenterView property of the DoughnutSeries, as per the following code example.

xmlns:chart="clr-namespace:Syncfusion.Maui.Charts;assembly=Syncfusion.Maui.Charts"

<chart:SfCircularChart>
.  .  . 
    <chart:SfCircularChart.Series>

        <chart:DoughnutSeries ItemsSource="{Binding Data}" InnerRadius="0.6" XBindingPath="Product"
                                                  YBindingPath="Revenue" ShowDataLabels="True">

            <chart:DoughnutSeries.CenterView>
                <StackLayout>
                    <Label Text="Total:" HorizontalOptions="Center"/>
                    <Label Text="$35.07K" HorizontalOptions="Center"/>
