Axis Labels
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.

// Use the Labeler property to give format to the axis values // mark
// Now the Y axis we will display it as currency
// LiveCharts provides some common formatters
// in this case we are using the currency formatter.
Labeler = Labelers.Currency // mark
// you could also build your own currency formatter
// for example:
// Labeler = (value) => value.ToString("C")
// But the one that LiveCharts provides creates shorter labels when
// the amount is in millions or trillions
