在LiveCharts中创建饼图切片

Question

我正在使用LiveCharts创建一个饼图。我有一个要在饼图中表示的替身列表。问题是列表的值可以并且将会更改，因此我希望能够相应地更改图表。

以下是来自LiveCharts网站的一些示例代码：

using System;
using System.Windows.Forms;
using LiveCharts;
using LiveCharts.Wpf;

namespace Winforms.PieChart
{
public partial class PieChartExample : Form
{
    public PieChartExample()
    {
        InitializeComponent();

        Func<ChartPoint, string> labelPoint = chartPoint =>
            string.Format("{0} ({1:P})", chartPoint.Y, chartPoint.Participation);

        pieChart1.Series = new SeriesCollection
        {
            new PieSeries
            {
                Title = "Maria",
                Values = new ChartValues<double> {3},
                PushOut = 15,
                DataLabels = true,
                LabelPoint = labelPoint
            },
            new PieSeries
            {
                Title = "Charles",
                Values = new ChartValues<double> {4},
                DataLabels = true,
                LabelPoint = labelPoint
            },
            new PieSeries
            {
                Title = "Frida",
                Values = new ChartValues<double> {6},
                DataLabels = true,
                LabelPoint = labelPoint
            },
            new PieSeries
            {
                Title = "Frederic",
                Values = new ChartValues<double> {2},
                DataLabels = true,
                LabelPoint = labelPoint
            }
        };

        pieChart1.LegendLocation = LegendLocation.Bottom;
    }
}

}

本质上，我想做同样的事情，但不是迭代列表，而是为饼图创建适当数量的切片。LiveCharts提供了PieSlices，但PieChart Control只接受SeriesCollection，这就是当我将pieChartData赋给图表时代码崩溃的原因。以下是我填充PieChart的尝试：

        LiveCharts.Wpf.PieChart pieChartData = new LiveCharts.Wpf.PieChart();

        foreach (var n in areavalues)
        {
            pieChartData.AddToView(new PieSlice
            {
                PieceValue = n
            });
        }

        areaChart.Series.Add(new PieSeries(pieChartData)); //<-- CRASH

我很难找到LiveCharts的其他示例代码，有人知道如何做到这一点吗？
