Trendlines are used to show the direction and speed of price.
Trendlines can be generated for Cartesian type series (Line, Column, Scatter, Area, Candle, Hilo etc.) except bar type series. You can add more than one trendline to a series.
Chart supports 6 types of trendlines.
A linear trendline is a best fit straight line that is used with simpler data sets. To render a linear trendline,
use trendline type as Linear and inject
Trendlines module using Chart.Inject(Trendlines).
