C# WPF ItemsControl 循环 LiveCharts X点 Y点 绑定Binding

在WPF中使用ItemsControl来循环绑定数据，并使用LiveCharts来绑定X和Y的点。

首先，你需要在你的XAML文件中创建一个ItemsControl来显示数据：

<ItemsControl ItemsSource="{Binding DataPoints}">
    <ItemsControl.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Horizontal" />
        </ItemsPanelTemplate>
    </ItemsControl.ItemsPanel>
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding X}" />
            <TextBlock Text="{Binding Y}" />
        </DataTemplate>
    </ItemsControl.ItemTemplate>
</ItemsControl>

然后，在你的ViewModel中创建一个名为DataPoints的可观察集合，用于存储X和Y的点：

public class ViewModel : INotifyPropertyChanged
{
    private ObservableCollection<DataPoint> _dataPoints;
    public ObservableCollection<DataPoint> DataPoints
    {
        get { return _dataPoints; }
        set
        {
            _dataPoints = value;
            OnPropertyChanged(nameof(DataPoints));
        }
    }

    public ViewModel()
    {
        DataPoints = new ObservableCollection<DataPoint>();
        // 添加一些点
        DataPoints.Add(new DataPoint(1, 2));
        DataPoints.Add(new DataPoint(3, 4));
        DataPoints.Add(new DataPoint(5, 6));
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected virtual void OnPropertyChanged(string propertyName)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

public class DataPoint
{
    public double X { get; set; }
    public double Y { get; set; }

    public DataPoint(double x, double y)
    {
        X = x;
        Y = y;
    }
}

最后，在你的MainWindow中设置DataContext为ViewModel的实例：

public MainWindow()
{
    InitializeComponent();
    DataContext = new ViewModel();
}

这样，你就可以在ItemsControl中循环绑定DataPoints中的点，并使用LiveCharts来显示X和Y的值
