Radial Area
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
using LiveChartsCore;
namespace ViewModelsSamples.Polar.RadialArea;
public class ViewModel
{
public int[] Values1 { get; set; } =
[7, 5, 7, 5, 6];
public int[] Values2 { get; set; } =
[2, 7, 5, 9, 7];
public string[] Labels { get; set; } =
["first", "second", "third", "forth", "fifth"];
public double TangentAngle { get; set; } =
LiveCharts.TangentAngle;
}
