Hi,



I'm trying to make a graph with 3 bars that each bar is connected to a specific legend.



For some reason, I get 3 bars for each x axis item.



I'm probably doing something wrong.

Hi,

In this scenario you need to use SeriesMapping.GroupingSettings in order to group the data by one or more parameters. For example:

<telerik:RadChart x:Name="radChart">

<telerik:RadChart.SeriesMappings>

<telerik:SeriesMapping >

<telerik:SeriesMapping.SeriesDefinition>

<telerik:BarSeriesDefinition />

</telerik:SeriesMapping.SeriesDefinition>

<telerik:SeriesMapping.GroupingSettings>

<telerik:GroupingSettings ShouldCreateSeriesForLastGroup="True">

<telerik:GroupingSettings.GroupDescriptors>

<telerik:ChartGroupDescriptor Member="TypeAmount"/>

</telerik:GroupingSettings.GroupDescriptors>

</telerik:GroupingSettings>

</telerik:SeriesMapping.GroupingSettings>

<telerik:SeriesMapping.ItemMappings>

<telerik:ItemMapping DataPointMember="YValue" FieldName="Amount" />

<telerik:ItemMapping DataPointMember="XCategory" FieldName="TypeAmount" />

</telerik:SeriesMapping.ItemMappings>

</telerik:SeriesMapping>

</telerik:RadChart.SeriesMappings>

</telerik:RadChart>

I hope this helps.
