Add an Indicator to a Series

This example demonstrates how to build a median price indicator for a stock series.

  1. Add the MedianPriceIndicator object to the chart's collection of series (ChartView.Series).
  2. Set the indicator's Data property to a CalculatedSeriesDataAdapter class instance. Use this object's Series property to specify a series for which the indicator should be calculated.
<dxc:ChartView x:Name="chart">
    <dxc:ChartView.Series>
        <dxc:StockSeries>
            <dxc:StockSeries.Data>
                <dxc:SeriesDataAdapter DataSource="{Binding StockPrices}" ArgumentDataMember="Date">
                    <dxc:ValueDataMember Type="High" Member="High" />
                    <dxc:ValueDataMember Type="Low" Member="Low" />
                    <dxc:ValueDataMember Type="Open" Member="Open" />
                    <dxc:ValueDataMember Type="Close" Member="Close" />
                </dxc:SeriesDataAdapter>
            </dxc:StockSeries.Data>
        </dxc:StockSeries>

        <dxc:MedianPriceIndicator VisibleInLegend="True"
                                  DisplayName="Median Price">
            <dxc:MedianPriceIndicator.Data>
                <dxc:CalculatedSeriesDataAdapter Series="{Binding Series[0], Source={x:Reference chart}}"/>
            </dxc:MedianPriceIndicator.Data>
        </dxc:MedianPriceIndicator>
    </dxc:ChartView.Series>
</dxc:ChartView>

Customize Indicator Appearance

To change the indicator line appearance, set the MedianPriceIndicator.Style property to the LineIndicatorStyle object with the specified Stroke and StrokeThickness properties.

    <dxc:MedianPriceIndicator.Style>
        <dxc:LineIndicatorStyle Stroke="#9859c9"/>
