Doughnut

This web site builds the control from code behind but you could also grab it from the toolbox, this sample also uses a ViewModel to populate the properties of the control(s) in this sample.

View model

using System.Collections.Generic;
using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;
using CommunityToolkit.Mvvm.ComponentModel;

namespace ViewModelsSamples.Pies.Doughnut;

[ObservableObject]
public partial class ViewModel
{
    public ISeries[] Series { get; set; } = new ISeries[]
    {
        new PieSeries<double> { Values = new List<double> { 2 }, InnerRadius = 50 },
        new PieSeries<double> { Values = new List<double> { 4 }, InnerRadius = 50 },
        new PieSeries<double> { Values = new List<double> { 1 }, InnerRadius = 50 },
        new PieSeries<double> { Values = new List<double> { 4 }, InnerRadius = 50 },
        new PieSeries<double> { Values = new List<double> { 3 }, InnerRadius = 50 }
    };
}

Form code behind

using System.Windows.Forms;
using LiveChartsCore.SkiaSharpView.WinForms;
using ViewModelsSamples.Pies.Doughnut;

namespace WinFormsSample.Pies.Doughnut;

public partial class View : UserControl
{
    private readonly PieChart pieChart;

    public View()
    {
        InitializeComponent();
        Size = new System.Drawing.Size(50, 50);

        var viewModel = new ViewModel();

        pieChart = new PieChart
        {
            Series = viewModel.Series,

            // out of livecharts properties...
            Location = new System.Drawing.Point(0, 0),
            Size = new System.Drawing.Size(50, 50),
            Anchor = AnchorStyles.Left | AnchorStyles.Right | AnchorStyles.Top | AnchorStyles.Bottom
        };

        Controls.Add(pieChart);
    }
}
