## org.faceless.graph.formatter
Class DiscreteFormatter

    java.lang.Object
      org.faceless.graph.formatter.Formatter
          org.faceless.graph.formatter.DiscreteFormatter

    public class DiscreteFormatter

extends Formatter

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.

Method Summary
`String` | `format(double in)` Return a String that is the formatted version of the input parameter.
`boolean` | `isDiscrete()` For this subclass, discrete returns true.

Constructor Detail

### DiscreteFormatter

    public DiscreteFormatter(List list)

  Create a new DiscreteFormatter

  Parameters:
    `list` - The list of values on the axis.

Method Detail

### isDiscrete

    public boolean isDiscrete()

  For this subclass, discrete returns true.

  Overrides:
    `isDiscrete` in class `Formatter`

### 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:
    `steps` in class `Formatter`
