        public void setCubicInterpolationMode​(CubicInterpolationMode mode)
        Sets algorithm used to interpolate a smooth curve from the discrete data points.

         'default'
 'monotone'

        The 'default' algorithm uses a custom weighted cubic interpolation, which produces pleasant curves for all types of datasets.
        The 'monotone' algorithm is more suited to y = f(x) datasets : it preserves monotonicity (or piecewise monotonicity) of the dataset 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
