Custom Separators Interval
The [ObservableObject], [ObservableProperty] and [ICommand] 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.

// the library will use this separators instead of
// calculating them based on the date of the chart

MinLimit = 0, // forces the axis to start at 0
