这种类型的图表称为嵌套饼图或多级饼图。它是通过创建两个ChartArea -饼图和圆环图来完成的，这两个图表相对于另一个正确放置。下面是代码。

public partial class Form1 : Form
{
    public class DataInt {
        public string Label { get; set; }
        public int Value { get; set; } }
    public Form1()
    {
        InitializeComponent();
        pieChart.Series.Clear();

        float outerSize = 80;
         
        ChartArea outerArea = new ChartArea("OUTER_AREA");
        outerArea.Position = new ElementPosition(0, 10, 100, 100);
        outerArea.InnerPlotPosition = new ElementPosition((100 - outerSize) / 2, (100 - outerSize) / 2, outerSize, outerSize);
        outerArea.BackColor = Color.Transparent;
         
        pieChart.ChartAreas.Add(outerArea);

        outerSeries["DoughnutRadius"] = Math.Min(baseDoughnutWidth * (100 / outerSize), 99).ToString().Replace(",", ".");

           new DataInt{Label="Red",Value=31}, new DataInt { Label = "Blue", Value = 48 } };

        innerSeries.Points.DataBindXY(innerData, "Label", innerData, "Value");
        outerSeries.Points.DataBindXY(outerData, "Label", outerData, "Value");

        pieChart.Series.Add(innerSeries);

        int inclination = 20;
        int rotation = 45;
        bool enable3d = true;
