public NullFormatter()
Method Detail

format

public String format(double in)
Description copied from class: Formatter
Return a String that is the formatted version of the input parameter.

Specified by:
format in class Formatter

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.

Overrides:
