Newbie chart question

[Ernstjan]

Hi All,

I'm struggeling for some time now with a radchart (piechart) I'm using in my application, the series are not displayed (probably), see attachment.
My XAML looks like this :

            <telerik:RadChart x:Name="RadChart1" Grid.Row="2" ItemsSource="{Binding}">
                <telerik:RadChart.DefaultView>
                    <telerik:ChartDefaultView ChartLegendPosition="{Binding LegendPosition, Mode=TwoWay}">
                        <telerik:ChartDefaultView.ChartTitle>
                            <telerik:ChartTitle>
                                Employee Actions
                            </telerik:ChartTitle>
                        </telerik:ChartDefaultView.ChartTitle>
                        <telerik:ChartDefaultView.ChartArea>
                            <telerik:ChartArea LabelFormatBehavior="None" LegendName="ChartLegend">
                            </telerik:ChartArea>
                        </telerik:ChartDefaultView.ChartArea>
                        <telerik:ChartDefaultView.ChartLegend>
                            <telerik:ChartLegend Name="ChartLegend"
                                                 LegendItemMarkerShape="{Binding ChartLegendItemMarkerShape, Mode=TwoWay}" />
                        </telerik:ChartDefaultView.ChartLegend>
                    </telerik:ChartDefaultView>
                </telerik:RadChart.DefaultView>
                <telerik:RadChart.SeriesMappings>
                    <telerik:SeriesMapping LegendLabel="Test" >
                        <telerik:SeriesMapping.SeriesDefinition>
                            <telerik:PieSeriesDefinition />
                        </telerik:SeriesMapping.SeriesDefinition>
                        <telerik:SeriesMapping.GroupingSettings>
                            <telerik:GroupingSettings>
                                <telerik:GroupingSettings.GroupDescriptors>
                                    <telerik:ChartGroupDescriptor Member="Type" />
                                </telerik:GroupingSettings.GroupDescriptors>
                            </telerik:GroupingSettings>
                        </telerik:SeriesMapping.GroupingSettings>
                        <telerik:SeriesMapping.ItemMappings>
                            <telerik:ItemMapping FieldName="Type"
                                            DataPointMember="XCategory" />
                            <telerik:ItemMapping FieldName="Type"
                                            DataPointMember="YValue"
                                            AggregateFunction="Count" />
                        </telerik:SeriesMapping.ItemMappings>
                    </telerik:SeriesMapping>
                </telerik:RadChart.SeriesMappings>
            </telerik:RadChart>


I would like to see a real pie chart with slices in different colors :)

Thanks in advance!

Hello Ernstjan,

To show a Pie Chart where each slice has different color you can follow our demo with sample code.
If you want to Populate the Chart with Manual Series Mappings, you can take a look at the sample project attached.
