      • getStepPoint

        public double getStepPoint()
        Returns the fraction of the domain position between two points on which the step is drawn. The default is 1.0d, which means the step is drawn at the domain position of the second`point. If the stepPoint is 0.5d the step is drawn at half between the two points.
        Returns:
        The fraction of the domain position between two points where the step is drawn.
        Since:
        1.0.10

      • setStepPoint

        public void setStepPoint​(double stepPoint)
        Sets the step point and sends a RendererChangeEvent to all registered listeners.
        Parameters:
        stepPoint - the step point (in the range 0.0 to 1.0)
        Since:
        1.0.10
