Hide DataPoints in chart control from WinRT XAML Toolkit

Question

Is it possible to hide the data points in the chart control from the WinRT XAML Toolkit from CodePlex? I'm using a LineSeries and only want a line without the dots.

It should be the same approach as in Silverlight Toolkit since that is where we ported it from. You can probably change the template for the data points. — Filip Skakun, Oct 30 '12 at 21:37
Yes, but how I have to change the style for the data points. This is the question. — Thomas Sebastian Jensen, Oct 30 '12 at 21:41

This seems to work. Though I am not yet sure why it makes my lines orange...

<charting:Chart
    x:Name="LineChart2"
    Title="Line Chart Without Data Points"
    Margin="70,0">
    <charting:LineSeries
        Title="Population"
        IndependentValueBinding="{Binding Name}"
        DependentValueBinding="{Binding Value}"
        IsSelectionEnabled="True">
        <charting:LineSeries.DataPointStyle>
            <Style
                TargetType="charting:LineDataPoint">
                <Setter
                    Property="BorderThickness"
                    Value="0" />
                <Setter
                    Property="IsTabStop"
                    Value="False" />
                <Setter
                    Property="Width"
                    Value="0" />
                <Setter
                    Property="Height"
                    Value="0" />
                <Setter
                    Property="Template">
                    <Setter.Value>
                        <ControlTemplate
                            TargetType="charting:LineDataPoint">
                            <Grid
                                x:Name="Root"
                                Opacity="0" />
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </charting:LineSeries.DataPointStyle>
    </charting:LineSeries>
</charting:Chart>

Yeah! It's working great, but you are right the color of the line is acutally orange, but this is not a problem for me. But if I have only one point to display, I see nothing on the graph, because of hiding the points. Is it possible to change the Style, if I have only one point to display? Thanks. — Thomas Sebastian Jensen, Oct 31 '12 at 05:29
Of course - you could either use a different template depending on your data or modify the code of the line series to enable your scenario. — Filip Skakun, Oct 31 '12 at 15:34

@Filip Skakun thanks for the very accurate answer, and about your issue regarding Orange Lines try adding this property and change the color to whatever color you want.

<Charting:LineSeries.DataPointStyle>
                            <Style TargetType="Charting:LineDataPoint">

                                <Setter Property="Background" Value="Red" />
                                <Setter Property="Template">
                                    <Setter.Value>
                                        <ControlTemplate TargetType="Charting:LineDataPoint">
                                            <Grid x:Name="Root" Opacity="0" />
                                        </ControlTemplate>
                                    </Setter.Value>
                                </Setter>
                            </Style>
                        </Charting:LineSeries.DataPointStyle>

it happens mainly because Chart's are capable of displaying multiple data series on single chart. and for Series[0] the default color is set to Orange.
