Scatter Plots and Date Times

[Gareth McNicol]

When I have a scatter point series where xvalue mapping is a date time and the chart's horizontal axis is a DateTimeContinuousAxis I get nothing plotted.

I can't imagine I'm the only one wanting to plot time series data without using the line series?

Is there a way to use the line series but not draw the lines, but draw the points?

Setting the point template and setting the stroke thickness gets me halfway there but the fill of the ellipse is wrong...

<telerik:LineSeries CategoryBinding="X" ValueBinding="Y" StrokeThickness="0" ItemsSource="{Binding Data}">
    <telerik:LineSeries.PointTemplate>
        <DataTemplate>
            <Ellipse Height="3" Width="3" Fill="{Binding Stroke, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type telerik:LineSeries}}, BindsDirectlyToSource=True, UpdateSourceTrigger=PropertyChanged}" />
        </DataTemplate>
    </telerik:LineSeries.PointTemplate>
</telerik:LineSeries>

How would one bind it to the palette  which is metro.

Hello Gareth,

If you need the accent color from our metro theme, you need to use the following DataTemplate:

<telerik:MetroColors x:Key="MetroColors" />
<SolidColorBrush x:Key="AccentBrush" Color="{Binding Source={StaticResource MetroColors}, Path=Palette.AccentColor}"/>
<DataTemplate x:Key="pointTemplate">
    <Grid>
        <Ellipse Fill="{StaticResource AccentBrush}" Height="15" Width="15"/>
    </Grid>
</DataTemplate>

But if you have set the Metro palette to your RadChartView then use:

<DataTemplate x:Key="pointTemplate2">
    <Grid>
        <Ellipse Fill="{Binding ElementName=chart, Path=Palette.GlobalEntries[1].Fill}" Height="15" Width="15"/>
    </Grid>
</DataTemplate>

where chart is the x:Name.

I hope this helps.
