29 Apr 20261 minute to read

Adornments (Data Markers) are used to provide information about the data points to the user. Values from data point(x, y) or other custom properties from a data source can be displayed.You can add a shape and label to adorn each data point.

Each adornment can be represented by the following:

• Marker- Displays the desired symbol at the (X, Y) point.
• Label - Displays the segment label content at the (X, Y) point.
• ConnectorLine - Line used to connect the (X, Y) point and the label element.

The following code example illustrates how to initialize the adornment.

XAML

<chart:ColumnSeries3D ItemsSource="{Binding CategoricalData}" XBindingPath="Year" YBindingPath="Plastic">

    <!--AdornmentsInfo-->
    <chart:ColumnSeries3D.AdornmentsInfo>
        <chart:ChartAdornmentInfo3D 
            UseSeriesPalette="True" 
            BorderBrush="White" 
            BorderThickness="1" 
            ShowLabel="True">
        </chart:ChartAdornmentInfo3D>
    </chart:ColumnSeries3D.AdornmentsInfo>
</chart:ColumnSeries3D>

C#

ColumnSeries3D series = new ColumnSeries3D()
{
    ItemsSource = new ViewModel().CategoricalData,
    XBindingPath = "Year",
    YBindingPath = "Plastic"
};

ChartAdornmentInfo3D adornmentInfo = new ChartAdornmentInfo3D() 
{ 
    ShowLabel = true 
};

series.AdornmentsInfo = adornmentInfo;

chart.Series.Add(series);
