Data Markers in WPF Charts (SfChart)

12 Jan 20242 minutes to read

Chart adornments (Data Markers) are used to display values related to a chart segment element. Values from data point(x, y) or other custom properties from a data source can be displayed.

Each adornment can be represented by the following:

  • Label - Displays the segment label content at the (X, Y) point.
  • Marker- Displays the desired symbol 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.

<syncfusion:ColumnSeries Interior="#777777" ItemsSource="{Binding Demands}" XBindingPath="Category" YBindingPath="Value">
ColumnSeries series = new ColumnSeries()
                ItemsSource = ViewModel().Demands,
                XBindingPath = "Demands",
                YBindingPath = "Value",
                Interior = new SolidColorBrush(Color.FromRgb(0x77, 0x77, 0x77))
        ChartAdornmentInfo adornmentInfo = new ChartAdornmentInfo();
        series.AdornmentsInfo = adornmentInfo;
