Line Smoothness
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.
View model
namespace ViewModelsSamples.Lines.Straight;
public class ViewModel
{
public double[] Values1 { get; set; } =
[5, 0, 5, 0, 5, 0];
public double[] Values2 { get; set; } =
[7, 2, 7, 2, 7, 2];
}
