I have a PieChart (PieSeries) that I want to customize.

Unfortunatly when I use Blend to edit the DataPointStyle, Blend does put enough XAML in the style to draw the pie slices. The pie chart becomes a blank window. Where can I get a default DataPointStyle from so that I can start tweeking from a working style?

Here is the Xaml that Blend gives me:

<Style x:Key="PieDataPointStyle1" TargetType="{x:Type chartingToolkit:PieDataPoint}">
    <Setter Property="Background" Value="Orange"/>
    <Setter Property="BorderBrush" Value="White"/>
    <Setter Property="BorderThickness" Value="1"/>
    <Setter Property="IsTabStop" Value="False"/>
    <Setter Property="RatioStringFormat" Value="{}{0:p2}"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type chartingToolkit:PieDataPoint}">
                <Grid x:Name="Root" Opacity="0">
                    <Path x:Name="Slice" Data="{TemplateBinding Geometry}" Stroke="{TemplateBinding BorderBrush}" StrokeMiterLimit="1" Fill="#FF1C3C7C">
                        <Path.ToolTip>
                            <StackPanel>
                                <ContentControl Content="{TemplateBinding FormattedDependentValue}"/>
                                <ContentControl Content="{TemplateBinding FormattedRatio}"/>
                            </StackPanel>
                        </Path.ToolTip>
                    </Path>
                    <Path x:Name="SelectionHighlight" Data="{TemplateBinding GeometrySelection}" Fill="Red" IsHitTestVisible="False" Opacity="0" StrokeMiterLimit="1"/>
                    <Path x:Name="MouseOverHighlight" Data="{TemplateBinding GeometryHighlight}" Fill="White" IsHitTestVisible="False" Opacity="0" StrokeMiterLimit="1"/>
                </Grid>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
