WPF Chart - Empty Values - Telerik UI for WPF

I have added link for EmptyPointBehaviour for wpf but it's available for windows, I want to implement same for wpf or uwp xaml UI.

Hello Priti,

The provided link is for the old WPF RadChart control. Instead, I recommend you to use RadChartView for WPF. In this case, you can see the following article that shows how to add empty points in the chart.

Please see below code 

telerikChart:RadCartesianChart x:Name="lineSeries" PaletteName="DefaultLight" >
            <telerikChart:RadCartesianChart.VerticalAxis>
                <telerikChart:LinearAxis/>
            </telerikChart:RadCartesianChart.VerticalAxis>
            <telerikChart:RadCartesianChart.HorizontalAxis>
                <telerikChart:CategoricalAxis/>
            </telerikChart:RadCartesianChart.HorizontalAxis>
            <telerikChart:LineSeries  ItemsSource="{Binding}" x:Name="lseries">
                <telerikChart:LineSeries.CategoryBinding>
                <telerikChart:PropertyNameDataPointBinding PropertyName="Category"/>
                </telerikChart:LineSeries.CategoryBinding>
                <telerikChart:LineSeries.ValueBinding>
                    <telerikChart:PropertyNameDataPointBinding PropertyName="Value"/>
                </telerikChart:LineSeries.ValueBinding>
                <telerikChart:LineSeries.DefaultVisualStyle>
                    <Style TargetType="Path">
                        <Setter Property="Width" Value="10" />
                        <Setter Property="Height" Value="10" />
                        <Setter Property="Fill" Value="#FF5AC3" />
                    </Style>
                </telerikChart:LineSeries.DefaultVisualStyle>
            </telerikChart:LineSeries>
  </telerikChart:RadCartesianChart>



          List<Data> data = new List<Data>();
            data.Add(new Data() { Category = "Apples", Value = 5 });
            data.Add(new Data() { Category = "Oranges", Value = 9 });
            data.Add(new Data() { Category = "Peru", Value = float.NaN,  });
            data.Add(new Data() { Category = "Chiku", Value = float.NaN });
            data.Add(new Data() { Category = "Potato", Value = float.NaN });
            data.Add(new Data() { Category = "a", Value = float.NaN });
            data.Add(new Data() { Category = "b", Value = float.NaN });
            data.Add(new Data() { Category = "c", Value = float.NaN });
            data.Add(new Data() { Category = "d", Value = 4 });
            data.Add(new Data() { Category = "e", Value = float.NaN });
            data.Add(new Data() { Category = "f", Value = 3 });
            data.Add(new Data() { Category = "g", Value = float.NaN });
            data.Add(new Data() { Category = "h", Value = 8 });

            lseries.PointTemplate = this.Resources["PointTemplate"] as DataTemplate;

            this.lineSeries.DataContext = data;

It is Windows 8.1 App,

With this type of code and data I want to see the graph that we see after applying Drop option, is it possible to do so?

RadChartView for WPF doesn't have a PaletteName property. Do you use another product? If so, can you tell me which one?
