MS Charts C＃DataSource from array or List

我想从二维数组中的值填充图表的数据，一列将呈现X轴，第二列呈现Y轴..我做了它，但它不是从数组读取，它给出我运行应用程序时的默认行，我发现使用List 的解决方案，我有一个错误，所以如果任何人可以帮助我，我会感激：D

这是代码

Answer 1

在XY类中，而不是私有字段：

  private double X; private double Y; 

使用公共属性：

  public double X { get; private set; } public double Y { get; private set; } 

DataBinding不适用于字段。
