                               <Setter.Value>
                                   <telerik:SeriesLegendSettings Title="{Binding Label}"/>
                               </Setter.Value>
                            </Setter>
                            <Setter Property="Stroke" Value="{Binding Color}" />
                            <Setter Property="VerticalAxis" Value="{Binding VerticalAxis}"/>
                        </Style>
                    </telerik:CategoricalSeriesDescriptor.Style>
                </telerik:CategoricalSeriesDescriptor>
            </telerik:ChartSeriesProvider.SeriesDescriptors>
        </telerik:ChartSeriesProvider>
    </telerik:RadCartesianChart.SeriesProvider>
    <radchartview:RadCartesianChart.HorizontalAxis>
        <chartview:DateTimeContinuousAxis x:Name="horizontalAxis" PlotMode="BetweenTicks" ShowLabels="True" LabelFormat="{Binding AxisLabel}" MajorTickStyle="{StaticResource tickStyle}" LabelFitMode="Rotate" Minimum="{Binding StartDate}" Maximum="{Binding EndDate}"/>
    </radchartview:RadCartesianChart.HorizontalAxis>
</telerik:RadCatresianChart>

This is my XAML code. When I change the SuppChart collection (ObservableCollection) the chart isn't render the horizontal axis and annotation. I implement INotifyPropertyChanged and INotifyCollectionChanged. Data are render properly after collection change.

I attached picutures of plot before and after refresh the data. 

What can be wrong? I missing something?

Hi Paul,

It does not become clear what might be causing this unexpected behavior. I tried to reproduce the issue but to no avail. Could you please send us the rest of the code in a sample runnable project. This way we would be able to debug it locally and provide you with a possible solution. As this is a forum thread, you could either attach the project by opening a support ticket or use a third party website for upload files.
