Grouped And Stacked Bars

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 ContentPage instance, but LiveCharts controls can be used inside any container.
