Additional information available during function evaluation

(optional) True to update the secant line by evaluating fn with the current mouse position (x0 is the fixed point and x1 is computed dynamically based on the current mouse position)

The abscissa of the first point i.e. the secant will always intersect the point (x0, fn(x0))

(optional if updateOnMouseMove is set) The abscissa of the second point i.e. the secant will always intersect the point (x1, fn(x1)), requires x0 to be set
