WPF Toolkit Chart - Rolling Point Chart

Question

I have a chart with 1000 data points, and I am wondering how to delete data points? They significantly slow down the whole process. I investigated the need for a style change, is there any other way?

Deleting (collapsing) DataPoints in LineSeries?

<Grid>
    <chartingToolkit:Chart
       Width="Auto" Height="Auto"
       Background="Transparent" Panel.ZIndex="3">
        <chartingToolkit:LineSeries Title="Symbol" Background="Transparent"
      IndependentValueBinding="{Binding Path=Key}"
      DependentValueBinding="{Binding Path=Value}"
      ItemsSource="{Binding Path=SymbolData}" 
      DataContext="{Binding}">
            <chartingToolkit:LineSeries.DataPointStyle>
                <Style TargetType="{x:Type chartingToolkit:LineDataPoint}">
                    <Setter Property="Background" Value="Red"/>
                    <Setter Property="Visibility" Value="Collapsed"/>
                </Style>
            </chartingToolkit:LineSeries.DataPointStyle>
        </chartingToolkit:LineSeries>
    </chartingToolkit:Chart>
</Grid>

I thought the code above would work, but apparently not ...

Further research, even this answer did not help: /

Remove markers from a row or silverlight series

Cheers for help.
