Unable to show data using Series Provider and ScatterSplineSeries

[Julio]

Hello,

I am having difficulties in creating a RadCartesianChart Series Provider with a chart type of ScatterSplineSeries. In overview website (http://docs.telerik.com/devtools/silverlight/controls/radchartview/features/chartseriesprovider#overview), it states that to use ScatterSplineSeries, I need to use the ScatterSeriesDescriptor. But for some reason, the plot is not showing. I am just randomizing the data points in the viewmodel. If i remove the Style section, it is able to plot a Scatter Series. How do I go about to plot a Scatter Spline Series?

01.<telerik:RadCartesianChart Margin="10">

02. 

03.               <telerik:RadCartesianChart.HorizontalAxis>

04.                   <telerik:LinearAxis />

05.               </telerik:RadCartesianChart.HorizontalAxis>

06. 

07.               <telerik:RadCartesianChart.VerticalAxis>

08.                   <telerik:LinearAxis />

09.               </telerik:RadCartesianChart.VerticalAxis>

10. 

11.               <telerik:RadCartesianChart.SeriesProvider>

12.                   <telerik:ChartSeriesProvider Source="{Binding Data}">

20.                                   <Style TargetType="telerik:ScatterSplineSeries">

21.                                       <Setter Property="Stroke" Value="Blue" />

22.                                       <Setter Property="StrokeThickness" Value="1" />

23.                                   </Style>

24.                               </telerik:ScatterSeriesDescriptor.Style>

25. 

26.                           </telerik:ScatterSeriesDescriptor>

27.                       </telerik:ChartSeriesProvider.SeriesDescriptors>

28.                   </telerik:ChartSeriesProvider>

29.               </telerik:RadCartesianChart.SeriesProvider>

30.           </telerik:RadCartesianChart>

 

1.public class SeriesViewModel
2.    {
3.        public string SeriesType { get; set; }
4.        public ObservableCollection<TransmitDataItem> TransmitCharacterizationItems { get; set; }
5.    }

 

1.public class TransmitDataItem
2.    {
3.        public double XValue { get; set; }
4.        public double? YValue { get; set; }
5.    }

Spend to much time trying to find a simple answer, but lucklily I found it here: http://www.telerik.com/forums/categoricalseriesdescriptor-causes-chartview-failure#0Onp5xuIJkS5I1RbT562ZQ

Needed to add: BasedOn="{StaticResource ScatterSplineSeriesStyle}" in order to get it to work.

Hello Julio,

We are happy to hear that you have found a solution for your case. 

This behavior is expected if you are using NoXaml binaries in your application. When working with our NoXaml binaries and Implicit Styles you need to have in mind that your custom Styles that target our controls should be based on their default styles. You can do this by setting the BasedOn property of the custom Style. You can find more information in our Styling the Controls article.
