Hello All,
i have been trying to use sfchart in my xamarin.forms project (not pcl) . and i am following the examples given in documentation, but the chart is not rendering in my application. while the same code is working in your provided sample projects.
i am using latest Xamarin.Forms and
sfchart from your nuget packages
  • syncfusion.xamarin.sfchart
  • Syncfusion.SfChart.Android15.2451.0.43
  • Syncfusion.SfChart.XForms.Android15.2451.0.43
  • Syncfusion.SfChart.XForms15.2451.0.43
below is code in my project for sfchart :
user history.xaml page
<?xml version="1.0" encoding="utf-8" ?>
<bottomTabs:BottomTabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
             x:Class="pranjalApp.Views.userHistory" NavigationPage.HasNavigationBar="False">
    <!--Pages can be added as references or inline-->
    <ContentPage Title="Payment History">
            <StackLayout x:Name="pieStack">
                <chart:SfChart x:Name="Chart" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">

                        <chart:ChartTitle Text="Expenditures"/>

                        <local:PieSeriesViewModel />


                        <chart:PieSeries ItemsSource="{Binding PieSeriesData}" XBindingPath="Name" YBindingPath="value" StartAngle="75"  EnableAnimation="True"
                         EndAngle ="435" EnableSmartLabels="True" ConnectorLineType = "Bezier" DataMarkerPosition = "OutsideExtended" LegendIcon="Rectangle">
                                <chart:ChartDataMarker LabelContent="Percentage" ShowLabel="True">
                                        <chart:DataMarkerLabelStyle LabelPosition="Center"/>


    <ContentPage Title="Recharge History" >

userHistory.cs file:
    public partial class userHistory : BottomTabbedPage
        public userHistory ()
            if (!(Device.OS == TargetPlatform.Android || Device.OS == TargetPlatform.iOS))
                Chart.Series[0].AnimationDuration = 2;
                (Chart.Series[0] as PieSeries).StartAngle = 0;
                (Chart.Series[0] as PieSeries).EndAngle = 360;
            Chart.Series[0].BindingContext = new pranjalApp.ViewModels.PieSeriesViewModel();
        protected override void OnPagesChanged(NotifyCollectionChangedEventArgs e)

pieseriesviewmodel class:
public class PieSeriesViewModel
        public ObservableCollection<ChartDataModel> PieSeriesData { get; set; }

        public PieSeriesViewModel()
            PieSeriesData = new ObservableCollection<ChartDataModel>
                new ChartDataModel("Other personal", 94658),
                new ChartDataModel("Medical care", 9090),
                new ChartDataModel("Housing", 2577),
                new ChartDataModel("Transportation", 473),
                new ChartDataModel("Education", 120),
                new ChartDataModel("Electronics", 70)
public class ChartDataModel
        private string Expense;
        private int value;

        public ChartDataModel(string Expense, int value)
            this.Expense = Expense;
            this.value = value;
