Pushout
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
{
// you can convert any array, list or IEnumerable<T> to a pie series collection:
public IEnumerable<ISeries> Series { get; set; } =
new[] { 6, 5, 4, 3, 2 }.AsPieSeries((value, series) =>
{
// pushes out the slice with the value of 6 to 30 pixels.
if (value != 6) return;
series.Pushout = 30;
});
