Question about ChartAdornmentInfo SymbolTemplate

Hello,

I try to migrate my Telerik chart to Syncfusion in order to just use Syncfusion as library and I have some problems

I attached two files :
- Current.png - Syncfusion actual rendering
- Wanted.png - Telerik actual rendering

My problems :
- How to set the SymbolTemplate Width the same with as the ColumnSegment
- How to bind SymbolTemplate to ColumSegment DataContext
- How to add centered label to the colum segment ?



My code is :

<charts:SfChart Width="{x:Bind ViewModel.ChartWidth, Mode=OneWay}" AreaBorderThickness="0">
                        <charts:SfChart.SecondaryAxis>
                            <charts:NumericalAxis Visibility="Collapsed" ShowGridLines="False" />
                        </charts:SfChart.SecondaryAxis>
                        <charts:SfChart.PrimaryAxis>
                            <charts:CategoryAxis Visibility="Collapsed" ShowGridLines="False" />
                        </charts:SfChart.PrimaryAxis>
                        <charts:SfChart.Series>
                            <charts:ColumnSeries EnableAnimation="True" XBindingPath="Name" YBindingPath="Difference" ItemsSource="{x:Bind ViewModel.ChartParticipants, Mode=OneWay}">
                                <charts:ColumnSeries.CustomTemplate>
                                    <DataTemplate x:DataType="charts:ColumnSegment">
                                        <Canvas>
                                            <Rectangle Canvas.Left="{x:Bind RectX, Mode=OneWay}" Canvas.Top="{x:Bind RectY, Mode=OneWay}" Height="{x:Bind Height, Mode=OneWay}" Width="{x:Bind Width, Mode=OneWay}" Stretch="Fill" Fill="{x:Bind Item, Converter={StaticResource ParticipantToBrushConverter}}" />
                                        </Canvas>
                                    </DataTemplate>
                                </charts:ColumnSeries.CustomTemplate>
                                <charts:ColumnSeries.AdornmentsInfo>
                                    <charts:ChartAdornmentInfo AdornmentsPosition="Top" ShowLabel="True" ShowMarker="True" LabelPosition="Center" SegmentLabelContent="YValue">
                                        <charts:ChartAdornmentInfo.SymbolTemplate>
                                            <DataTemplate x:DataType="charts:ChartAdornmentInfo">
                                                <controls:ParticipantImage HasImage="False" Initial="GT" Height="{x:Bind  SymbolWidth, Mode=OneWay}" Width="{x:Bind SymbolWidth, Mode=OneWay}" />
                                            </DataTemplate>
                                        </charts:ChartAdornmentInfo.SymbolTemplate>
                                    </charts:ChartAdornmentInfo>
                                </charts:ColumnSeries.AdornmentsInfo>
                            </charts:ColumnSeries>
                        </charts:SfChart.Series>
                       
                    </charts:SfChart>

Thanks in advance,
Geoffrey

Hi Geoffery, 
  
Thanks for contacting Syncfusion Support. 
  
By default, the chart adornment symbol will render within the segment area. However, we have achieved your requirement by using the scatter series. 
  
We have prepared a demo sample for your reference and it can be downloaded from below link, 
  
  
Regards, 
Devi
