How to bind a list of Tuple in WPF Charts?

1 min read

This article describes how to bind the list of tuples as ItemSource in WPF Chart.

A tuple is a data structure that contains a sequence of elements of different data types. Tuple can be used as a model data for data source.

Let us see the simple example of displaying currency information in WPF chart using the tuple by following these steps:

 

Step 1: Create the required view model with collection property of tuple type to store the currency code and the currency name.

    public class CurrencyViewModel
    {
         /// <summary>
         /// Tuple to store Currency information
         /// </summary>
        public List<Tuple<string, double>> Tuples
        {
            get;
            set;
        }
        
        public CurrencyViewModel()
        {
            Tuples = new List<Tuple<string, double>>();
            Tuples.Add(new Tuple<string, double>("Dollar", 784));       
            Tuples.Add(new Tuple<string, double>("Euro", 978));  
            Tuples.Add(new Tuple<string, double>("Yen", 484));
            Tuples.Add(new Tuple<string, double>("Peso", 554));
            Tuples.Add(new Tuple<string, double>("Riyal", 682));
            Tuples.Add(new Tuple<string, double>("Rupee", 840));        
  }
    }

 

Step2 : Bind the Tuples property as ItemSource and just bind Item1 and Item2 to XBindingPath and YBindingPath properties of series, respectively.

 

    <!--Assign the DataContext-->
    <Window.DataContext>
        <viewmodel:CurrencyViewModel></viewmodel:CurrencyViewModel>
    </Window.DataContext>
 
 
 <Grid>      
 <!—Chart-->  
        <chart:SfChart Width="500" Height="400">
            <chart:SfChart.PrimaryAxis>
                <chart:CategoryAxis />
            </chart:SfChart.PrimaryAxis>
           
            <chart:SfChart.SecondaryAxis>
                <chart:NumericalAxis />
            </chart:SfChart.SecondaryAxis>
            
            <!--Bind Tuples to Series-->
            <chart:ColumnSeries ItemsSource="{Binding Tuples}"      Palette="BlueChrome" XBindingPath="Item1" YBindingPath="Item2" />
        </chart:SfChart>
    
 </Grid>

 

Output

Tuple as ItemSource of chart series.
