Custom Separators Interval

This sample uses C# 13 preview features such as partial properties, it also uses features from the CommunityToolkit.Mvvm package, you can learn more about it here.

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