org.faceless.graph.formatter.DiscreteFormatter
public class DiscreteFormatter
The DiscreteFormatter
treats it's double
argument as an index into a list of String values, and
returns the matching String.
This is the formatter that's used to plot the String values on the X axis of a Bar Graph, but it's probably not suitable for general use.

public double[] steps(double min, double max)
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.
