A regression line is a series indicator that allows you to perform linear regression analysis over your series data. The analysis aims to find a line that is as close to all points of a series as possible using the method of least squares to determine the line equation.

Regression Line Indicator

Add an Indicator to a Series

This example demonstrates how to build a regression line based on High values of a stock series.

  1. Add the RegressionLineIndicator 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.
  3. Set the ValueLevel property to High to specify a point value used to build a regression line.
<dxc:ChartView x:Name="chart">
                <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:RegressionLineIndicator ValueLevel="High"
                                     DisplayName="Regression Line">
                <dxc:CalculatedSeriesDataAdapter Series="{Binding Series[0], Source={x:Reference chart}}"/>

Customize Indicator Appearance

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

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