After the fnDeleteAllTrendLines function has been added to a Drawing, it is configured by clicking the (+) button along the bottom of the Element.
The fnDeleteAllTrendLines function does not require any parameters.
Note: Any and all trend lines are deleted from the price chart. This includes trend lines created both manually and programatically.
