         'default'
 'monotone'

        The 'default' algorithm uses a custom weighted cubic interpolation, which produces pleasant curves for all types of data sets.
        The 'monotone' algorithm is more suited to y = f(x) data sets : it preserves monotonicity (or piecewise monotonicity) of the data set being interpolated, and ensures local extremums (if any) stay at input data points.

        mode - algorithm used to interpolate a smooth curve from the discrete data points

        public CubicInterpolationMode getCubicInterpolationMode()
