[Sergei]

Hello! Ineed to print Adornment for only one Axis, like this -> Sample

Try this :

   <chart:SplineSeries Name="MaxStroke" Opacity="1"  StrokeThickness="3.6" Interior="Red"

                ItemsSource="{Binding ChartPlpanMax}" XBindingPath="Name" YBindingPath="Value">

                <chart:SplineSeries.AdornmentsInfo>

                    <chart:ChartAdornmentInfo Symbol="Ellipse" SymbolInterior="Red" SymbolStroke="Wheat" SymbolHeight="12" SymbolWidth="12">

                    </chart:ChartAdornmentInfo>

                </chart:SplineSeries.AdornmentsInfo>

            </chart:SplineSeries>

Result -> MySample

As you can see, adornments was sets on all axes. How can I set it in only One ?

Hi Sergei, 

 

Thanks for contacting Syncfusion Support. 

 

We have analyzed your requirement(displaying adornment for only one data point) and this can be possible with the help of SymbolTemplate of chart adornment. Using converter to the symbol template, we can collapse the other adornments visibility and can display only required index adornment. Please refer the below codes, 

Code Snippet[XAML] 

<Grid.Resources> 

       <local:AdonrnmentConverter x:Key="adorn"/> 

</Grid.Resources> 

 

<chart:SplineSeries Opacity="1"  StrokeThickness="3.6" Interior="Red" ItemsSource="{Binding Collection}" XBindingPath="XValue" YBindingPath="YValue3"> 

                 

    <chart:SplineSeries.AdornmentsInfo> 

         <chart:ChartAdornmentInfo  > 

                        <chart:ChartAdornmentInfo.SymbolTemplate> 

                            <DataTemplate> 

                                <Ellipse Visibility="{Binding Converter={StaticResource adorn}}" Height="12" Width="12" Stroke="White" Fill="{Binding Interior}"/> 

                            </DataTemplate> 

                        </chart:ChartAdornmentInfo.SymbolTemplate> 

          </chart:ChartAdornmentInfo> 

    </chart:SplineSeries.AdornmentsInfo> 

</chart:SplineSeries> 

 

Code Snippet[C#] 

public class AdonrnmentConverter : IValueConverter 

{ 

   public object Convert(object value, Type targetType, object parameter, CultureInfo culture) 

   { 

            var adonr = value as ChartAdornment; 

            if (adonr.XData == 4) 

                return Visibility.Visible; 

            else 

                return Visibility.Collapsed; 

   } 

 

} 

 

 

Please find the output screenshot,
