How to bind Annotations of MainChartSurface to OverviewSurface

Hi there,

You can place anything in the SciChartOverview if you use this technique from the documentation.

How to: Create a Custom SciChartOverview with any Background

The SciChartOverview only supports a single series behind it, and does
not allow a custom background. You can however use the
SciChartScrollbar API to create a custom overview.

<Grid Background="{Binding ElementName=MainChartSurface, Path=Background}">
         <Grid.RowDefinitions>
               <RowDefinition Height="*" />
               <RowDefinition Height="100" />
         </Grid.RowDefinitions>
  
         
         <s:SciChartSurface x:Name="MainChartSurface">
            
         </s:SciChartSurface>
  
         
         <Grid Grid.Row="1" >
  
               
  
               
               <s:SciChartScrollbar Grid.Column="0"
                   Axis="{Binding ElementName=MainChartSurface, Path=XAxis}" />
         </Grid>
  </Grid>
  

Using this technique you can place anything behind a SciChartScrollbar to create an overview with custom series. You can place annotations on the series as well.

Just be advised that you cannot have the same Annotation instance on two SciChartSurfaces. This is because Annotations are UIElements and cannot have two parents.

If you want the same annotations on two charts they will need to be duplicated. This can be done with either SciChart’s MVVM Annotations API or with XAML or Code-behind annotations.
