3 bars for each x axis point instead of 1 bar

[IT Support]

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.

Can anybody help me?

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.

Kind regards,
