This example demonstrates how to build a regression line based on High values of a stock series.
- Add the RegressionLineIndicator object to the chart’s collection of series (ChartView.Series).
- 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.
- Set the
ValueLevel
property to High to specify a point value used to build a regression line.
