WPF: Chart is not plotting the chart

I am developing a Chart in WPF Application. But it is not showing the chart. Chart Plot area is blank whereas I can see the number of legends on the basis of number of valueList.add I do in the code.

XAML

<chartingToolkit:Chart HorizontalAlignment="Stretch"
                       x:Name="MyPie"
                       Margin="10"
                       Title="Total Voting Percentage"
                       VerticalAlignment="Stretch">
    <chartingToolkit:PieSeries ItemsSource="{Binding}"
                               DependentValuePath="Total Participants"
                               IndependentValuePath="Total Voted" />
</chartingToolkit:Chart>

Code Behind

public partial class TotalVoting : Window
{
    int TotalParticipant;
    int TotalVoted;
    public TotalVoting()
    {
        InitializeComponent();
        TotalParticipant = int.Parse(da[0].ToString()); //data reaches here
        TotalVoted = int.Parse(da1[0].ToString()) / 2; //data reaches here
        ObservableCollection<Writer> Team = new ObservableCollection<Writer> 
        { 
             new Writer("Total Participants", TotalParticipant), 
             new Writer("Participants Voted", TotalVoted),
             new Writer("Total Participants", TotalParticipant), 
             new Writer("Participants Voted", TotalVoted)
        };
        MyPie.DataContext = Team;
    }
}
public class Writer
{
    public Writer() { }
    public Writer(string writerName, int numOfTypes)
    {
        Name = writerName;
        Types = numOfTypes;
    }
    public string Name { get; set; }
    public int Types { get; set; }
}

When I run the code I can see the number of legends that too with number 1,2,3 ... so with current code it shows from 1 to 4. but doesn't show any chart on my chart control. Any clue so that I can get it done.

EDIT : A Change has been made to the code .. but still the same result

public void GenerateChart()
{
  List<KeyValuePair<string, double>> valueList = new List<KeyValuePair<string, double>>();
  valueList.Add(new KeyValuePair<string, double>("Apple", 101));
  valueList.Add(new KeyValuePair<string, double>("Banana", 201));
  valueList.Add(new KeyValuePair<string, double>("Cake", 20));
  valueList.Add(new KeyValuePair<string, double>("Others", 200));

  pieChart.Title = "Top Products";
  pieChart.DataContext = valueList;
}

the number of time valueList.Add is added. I can the same number of legends on the chart but no chart :(

Hope Somebody can help me !!!
