disable wpftoolkit chart datapoint

问题

Does anybody know how to turn off the datapoints for a noraml LineSeries in a WPFToolkit chart? I find them to be very annoying, and not useful to my purposes, but I can't find a simple property or anything like that on the class itself.

You want to hide them?

It is possible if to set the empty ControlTemplate to the Template property. Here is the example:

<Window.Resources>
    <Style x:Key="InvisibleDataPoint" TargetType="{x:Type charting:DataPoint}">
        <Setter Property="Background" Value="Blue"/>
        <Setter Property="Template" Value="{x:Null}"/>
    </Style>
</Window.Resources>
<Grid>
    <charting:Chart>
        <charting:LineSeries ItemsSource="{Binding ChartItems}" IndependentValuePath="XValue" DependentValuePath="YValue" 
                                 DataPointStyle="{StaticResource InvisibleDataPoint}"/>
    </charting:Chart>
</Grid>

And although the points are invisible, you can set other properties, like Background and change the look of chart.
