StackedBarSeries in xaml

[Stuart]

Hi

I'm trying to set up a stackedbarseriesdefinition chart but no combination of xaml seems to work for me.

My data is

qtr    sector        data
q1    ents            23.5
q2    ents            34
q3    ents            25
q1    shopping     15
q2    shopping     17

etc

and my xaml is

<telerik:RadChart.SeriesMappings>
                <telerik:SeriesMapping>
                    <telerik:SeriesMapping.GroupingSettings>
                        <telerik:GroupingSettings StackGroupFieldName="sector">
                            <telerik:GroupingSettings.GroupDescriptors>
                                <telerik:ChartGroupDescriptor Member="sector"></telerik:ChartGroupDescriptor>
                            </telerik:GroupingSettings.GroupDescriptors>
                        </telerik:GroupingSettings>
                    </telerik:SeriesMapping.GroupingSettings>
                    <telerik:SeriesMapping.SeriesDefinition>
                        <telerik:StackedBarSeriesDefinition>
                        </telerik:StackedBarSeriesDefinition>
                    </telerik:SeriesMapping.SeriesDefinition>
                    <telerik:SeriesMapping.ItemMappings>
                        <telerik:ItemMapping DataPointMember="XCategory"  FieldName="qtr"/>
                        <telerik:ItemMapping DataPointMember="YValue" FieldName="data"/>
                    </telerik:SeriesMapping.ItemMappings>
                </telerik:SeriesMapping>
            </telerik:RadChart.SeriesMappings>
            <telerik:RadChart.DefaultView>
                <telerik:ChartDefaultView>
                    <telerik:ChartDefaultView.ChartTitle>
                        <telerik:ChartTitle />
                    </telerik:ChartDefaultView.ChartTitle>
                </telerik:ChartDefaultView>
            </telerik:RadChart.DefaultView>
        </telerik:RadChart>

but it keeps displaying a chart with each sector bar alongside each other within each qtr as opposed to what I want which is per qtr a stack of all the sector values for that qtr. Does anyone know what I need to change?

Thanks

Hi Stuart,

You can try to set the GroupSettings.StackGroupFieldName to "qtr". For example:

<telerik:RadChart x:Name="radChart1">
    <telerik:RadChart.SeriesMappings>
        <telerik:SeriesMapping>
            <telerik:SeriesMapping.GroupingSettings>
                <telerik:GroupingSettings StackGroupFieldName="qtr">
                    <telerik:GroupingSettings.GroupDescriptors>
                        <telerik:ChartGroupDescriptor Member="sector"/>
                    </telerik:GroupingSettings.GroupDescriptors>
                </telerik:GroupingSettings>
            </telerik:SeriesMapping.GroupingSettings>
            <telerik:SeriesMapping.SeriesDefinition>
                <telerik:StackedBarSeriesDefinition />
            </telerik:SeriesMapping.SeriesDefinition>
            <telerik:SeriesMapping.ItemMappings>
                <telerik:ItemMapping DataPointMember="XCategory"  FieldName="qtr"/>
                <telerik:ItemMapping DataPointMember="YValue" FieldName="data"/>
            </telerik:SeriesMapping.ItemMappings>
        </telerik:SeriesMapping>
    </telerik:RadChart.SeriesMappings>
    <telerik:RadChart.DefaultView>
        <telerik:ChartDefaultView>
            <telerik:ChartDefaultView.ChartTitle>
                <telerik:ChartTitle />
            </telerik:ChartDefaultView.ChartTitle>
        </telerik:ChartDefaultView>
    </telerik:RadChart.DefaultView>
</telerik:RadChart>

You can see the result in the attached image.

I hope this helps.
