Adornments in UWP Pivot Chart (SfPivotChart)

7 Jan 202524 minutes to read

Adornments are used to display data values of a chart segment with custom formatting options. The data point values (x,y) can be formatted by using the AdornmentsInfo property of the SfPivotChart. You can initialize the adornments as specified in the following code snippet.

<syncfusion:SfPivotChart.AdornmentsInfo>
    <syncfusion:PivotChartAdornmentsInfo/>
</syncfusion:SfPivotChart.AdornmentsInfo>
PivotChartAdornmentsInfo adornmentsInfo = new PivotChartAdornmentsInfo();
PivotChart1.AdornmentsInfo = adornmentsInfo;
Dim adornmentsInfo As New PivotChartAdornmentsInfo()
PivotChart1.AdornmentsInfo = adornmentsInfo

Each adornment can be represented by the following components:

  • Marker: Displays a symbol at the data point (x,y).
  • Label: Displays segmented label content at the data point (x,y).
  • Connector line: Connects a label element to a data point (x,y) using a line.

Marker

To enable a marker in adornments, the ShowMarker property is used. By default, no symbol is shown in adornments unless the desired symbol is specified.

The following code snippet demonstrates how to show cross-type markers in adornments.

<syncfusion:SfPivotChart.AdornmentsInfo>
    <syncfusion:PivotChartAdornmentsInfo ShowMarker="True" Symbol="Cross"/>
</syncfusion:SfPivotChart.AdornmentsInfo>
PivotChartAdornmentsInfo adornmentsInfo = new PivotChartAdornmentsInfo();
adornmentsInfo.ShowMarker = true;
adornmentsInfo.Symbol = ChartSymbol.Cross;
PivotChart1.AdornmentsInfo = adornmentsInfo;
Dim adornmentsInfo As New PivotChartAdornmentsInfo()
adornmentsInfo.ShowMarker = True
adornmentsInfo.Symbol = ChartSymbol.Cross
PivotChart1.AdornmentsInfo = adornmentsInfo

Customizing marker appearance

The marker’s size can be customized using the SymbolHeight and SymbolWidth properties; its appearance can be customized using the SymbolInterior and SymbolStroke properties respectively.

<syncfusion:SfPivotChart.AdornmentsInfo>
    <syncfusion:PivotChartAdornmentsInfo ShowMarker="True" Symbol="Ellipse" SymbolStroke="Red" SymbolInterior="White" 
                                         SymbolHeight="15" SymbolWidth="15"/>
</syncfusion:SfPivotChart.AdornmentsInfo>
PivotChartAdornmentsInfo adornmentsInfo = new PivotChartAdornmentsInfo();
adornmentsInfo.ShowMarker = true;
adornmentsInfo.Symbol = ChartSymbol.Ellipse;
adornmentsInfo.Stroke = new SolidColorBrush(Colors.Red);
adornmentsInfo.Stroke = new SolidColorBrush(Colors.White);
adornmentsInfo.SymbolHeight = 15;
adornmentsInfo.SymbolWeight = 15;
PivotChart1.AdornmentsInfo = adornmentsInfo;
Dim adornmentsInfo As New PivotChartAdornmentsInfo()
adornmentsInfo.ShowMarker = True
adornmentsInfo.Symbol = ChartSymbol.Ellipse
adornmentsInfo.Stroke = New SolidColorBrush(Colors.Red)
adornmentsInfo.Stroke = New SolidColorBrush(Colors.White)
adornmentsInfo.SymbolHeight = 15
adornmentsInfo.SymbolWeight = 15
PivotChart1.AdornmentsInfo = adornmentsInfo

Custom marker

You can specify a custom template to create your own symbols by using the SymbolTemplate property as shown in the following code snippet.

<syncfusion:SfPivotChart.AdornmentsInfo>
    <syncfusion:PivotChartAdornmentsInfo ShowMarker="True" Symbol="Custom">
        <syncfusion:PivotChartAdornmentsInfo.SymbolTemplate>
            <DataTemplate>
                <Image Source="ms-appx:///Assets/Clover.ico" Height="15" Width="15"/>
            </DataTemplate>
        </syncfusion:PivotChartAdornmentsInfo.SymbolTemplate>
    </syncfusion:PivotChartAdornmentsInfo>
</syncfusion:SfPivotChart.AdornmentsInfo>
PivotChartAdornmentsInfo adornmentsInfo = new PivotChartAdornmentsInfo();
adornmentsInfo.ShowMarker = true;
adornmentsInfo.Symbol = ChartSymbol.Custom;
adornmentsInfo.SymbolTemplate = Resources["CustomSymbol"] as DataTemplate;
PivotChart1.AdornmentsInfo = adornmentsInfo;
Dim adornmentsInfo As New PivotChartAdornmentsInfo()
adornmentsInfo.ShowMarker = True
adornmentsInfo.Symbol = ChartSymbol.Custom
adornmentsInfo.SymbolTemplate = TryCast(Resources("CustomSymbol"), DataTemplate)
PivotChart1.AdornmentsInfo = adornmentsInfo
