      • steps

        public double[] steps​(double min,
                      double max)
        Description copied from class: Formatter

        Which steps between min and max should be marked on the axis. This is an array because although the steps will usually be evenly spaced, they may not always be (see the DateFormatter for an example).

        This method returns the default settings, which is to calculate a number of "useful" values between min and max, possibly rounding those two values up or down to fit the scale. The number of values returned depends on the density setting.
