Basic

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 ContentPage instance, but LiveCharts controls can be used inside any container.

View model

using LiveChartsCore;

namespace ViewModelsSamples.Polar.Basic;

public class ViewModel
{
    public double[] Values { get; set; } =
        [15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1];

    public double CotangentAngle { get; set; } =
        LiveCharts.CotangentAngle;

    public double TangentAngle { get; set; } =
        LiveCharts.TangentAngle;
}
