Adding Pie series to Chart

**Sl1ver** · May 30 '13, 09:35 AM

I have a chart in xaml and binding data to it at the back, what im currently finding is that it adds the data to the legend but doesn't actually produce a pie chart

xaml

Code:

<!--Begin Custom Tab Item-->
                        <sdk:TabItem  Name="CustomTabItem" Cursor="Hand" Visibility="Visible">
                            <Grid HorizontalAlignment="Stretch" VerticalAlignment="Stretch">
                                <Grid.RowDefinitions>
                                    <RowDefinition Height="*" MaxHeight="300" />
                                    <RowDefinition Height="Auto" />
                                </Grid.RowDefinitions>
                                <charting:Chart x:Name="SamplePieChart" Title="Sample Pie Chart" BorderThickness="0"                                              
                                                MaxHeight="300"
                                                HorizontalAlignment="Stretch"
                                                VerticalContentAlignment="Top"/>
                                <TextBlock Text="This is for testing purposes" 
                                    Margin="10,10,10,20" FontSize="10" TextWrapping="Wrap"
                                    Grid.Row="1" />
                            </Grid>
                        </sdk:TabItem>

Data

Code:

ChartItems = new KeyValuePair<string, int>[4];

            ChartItems[0] = new KeyValuePair<string, int>("Lorem ipsum dolor sit amet", 20);
            ChartItems[1] = new KeyValuePair<string, int>("Maecenas iaculis dapibus", 90);
            ChartItems[2] = new KeyValuePair<string, int>("Nulla facilisi. Curabitur laoreet", 112);
            ChartItems[3] = new KeyValuePair<string, int>("Pellentesque non turpis elit", 160);

Code Behind

Code:

Chart pie = MapApplication.Current.FindObjectInLayout("SamplePieChart") as Chart;
                    pie.Series.Clear();
                    var Series = new PieSeries();
                    Series.ItemsSource = ChartItems;
                    Series.IndependentValueBinding = new Binding("Key");
                    Series.DependentValueBinding = new Binding("Value");
                    pie.Series.Add(Series);
