Extra Chart area in Chart.

[Eric]

Here is a Chart I'm working on: 

<Telerik:RadChart Height="750" x:Name="WeightsChart" Width="1400">
    <Telerik:RadChart.DefaultView>
        <Telerik:ChartDefaultView>
            <Telerik:ChartDefaultView.ChartTitle>
                <Telerik:ChartTitle Content="Catia Part and Assembly Weights" HorizontalAlignment="Center"/>
            </Telerik:ChartDefaultView.ChartTitle>
            <Telerik:ChartDefaultView.ChartLegend>
                <Telerik:ChartLegend Visibility="Collapsed"/>
            </Telerik:ChartDefaultView.ChartLegend>
            <Telerik:ChartDefaultView.ChartArea>
                <Telerik:ChartArea>
                    <Telerik:ChartArea.AxisX>
                        <Telerik:AxisX LabelRotationAngle="90"/>
                    </Telerik:ChartArea.AxisX>
                </Telerik:ChartArea>
            </Telerik:ChartDefaultView.ChartArea>
        </Telerik:ChartDefaultView>
    </Telerik:RadChart.DefaultView>
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="1*"/>
            <RowDefinition Height="1*"/>
        </Grid.RowDefinitions>
        <Telerik:ChartArea x:Name="BarChart" NoDataString="No Bar Series Data"/>
        <Telerik:ChartArea x:Name="LineChart" Grid.Row="1" NoDataString="No Line Series Data"/>
    </Grid>
    <Telerik:RadChart.HierarchicalViewDescriptors>

As you can see, I'm getting a mystery series in the center of my grid. How do I get rid of it? I'm having a lot of trouble setting up these charts.

Hello Eric,

This issue is more likely to appear if you don't use the DefaultView of the Chart.
You should set the corresponding ChartArea's Name to the SeriesMapping.ChartAreaName property.
If this doesn't help I would suggest that you send us your runnable project so that we will be able to investigate it locally and get back to you with our findings/suggestions based on the code.

Best wishes,
Evgenia
