How to bind the array property in WPF Chart (SfChart)?

Platform: WPF |
Control: SfChart |
Published Date: May 20, 2015 |
Last Revised Date: July 2, 2021

WPF Chart (SfChart) supports array values for the XBindingPath and YBindingPath. The XBindingPath and YBindingPath are bound with the property name in the corresponding index value. You can bind the same property with different index values.

public class TestClass
  public double X { get; set; }
  public double[] Y { get; set; }
public class TestClassCollection : ObservableCollection<TestClass>
  public TestClassCollection()
    this.Add(new TestClass { X = 1, Y = new double[] { 4, 10 } });
    this.Add(new TestClass { X = 2, Y = new double[] { 8, 15 } });
    this.Add(new TestClass { X = 3, Y = new double[] { 12,20 } });


<chart:ColumnSeries ItemsSource="{Binding}" XBindingPath="X" YBindingPath="Y[0]">


ColumnSeries series = new ColumnSeries() { XBindingPath = "X", YBindingPath = "Y[0]"};
