setMaximumAccelerationFactor(newMaximum): void
Sets the maximum value for Acceleration Factor. AF cannot go above this value.
Parameters
- newMaximum: number
  
  New maximum value for Acceleration Factor.
Returns void

setName

setName(name): void
Sets the name of the indicator.

Parameters
- newOffset: number
  
  New offset value.
