How to bind the array property in WPF SfChart?

The WPF Chart (SfChart) supports binding to array properties using the XBindingPath and YBindingPath. This allows you to visualize array-based data by specifying the index of the array element you want to display. You can bind the same property with different index values.

Data Model

Below is a simple example of a data model where each data point contains an X value and an array of Y 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 } });
  }
}

XAML

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

C#

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

chart.Series.Add(series);
