Line Smoothness

This sample uses C# 12 features, 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.

            Fill = null,
            GeometrySize = 0,
            // use the line smoothness property to control the curve
            // it goes from 0 to 1
            // where 0 is a straight line and 1 the most curved
            LineSmoothness = 0 // mark
        },
