Nightingale Rose

The [ObservableObject], [ObservableProperty] and [RelayCommand] attributes come from the CommunityToolkit.Mvvm package, you can read more about it here.

This web site wraps every sample using a UserControl instance, but LiveCharts controls can be used inside any container.

public partial class ViewModel : ObservableObject
    public ViewModel()
        var outer = 0;
        var data = new[] { 6, 5, 4, 3, 2 };

        // you can convert any array, list or IEnumerable<T> to a pie series collection:
        Series = data.AsPieSeries((value, series) =>
            // this method is called once per element in the array
            // we are decrementing the outer radius 50px
            // on every element in the array.

            series.InnerRadius = 50;
            series.OuterRadiusOffset = outer;
            outer += 50;

    public IEnumerable<ISeries> Series { get; set; }
