Class StringAxis

java.lang.Object
  jas.plot.AxisType
      jas.plot.StringAxis

All Implemented Interfaces:

CoordinateTransformation, StringCoordinateTransformation, Externalizable, Serializable

public final class StringAxis
extends AxisType
implements StringCoordinateTransformation

This class simply displays a given array of strings. Use for a histogram with a string partition, or if there are very specific labels (numeric or other) you want on the axis. This class displays strings in two formats, represented by two static constants:

• CENTER_TEXT_IN_DIVISION: a tick mark and label will be centered in a division
• TEXT_BESIDE_DIVISION: a tick mark and label will be on either side of a division

Use the method setLabelPlacementStyle(int) to change the setting.

Labels are displayed in the order as they appear in the array given to the method setLabels(String[]) from left to right on a horizontal axis and from bottom to top on a vertical axis.
