Trend Lines

Trend Line is a line drawn between any two points of a series to show the general direction that values are headed in. It can be limited by these two points or extrapolated to infinity.

Along with other indicators, Trend Lines reside in the XYDiagram2DSeriesViewBase.Indicators collection of a series. A series may have any number of Trend Lines. For more information refer to Trend Lines.
