Class GrannyTickLabeller

java.lang.Object
  org.das2.graph.GrannyTickLabeller

All Implemented Interfaces:

TickLabeller

public class GrannyTickLabeller
extends java.lang.Object
implements TickLabeller

TickLabeller based on the formatting and bounding-box capabilities of the GrannyTextRenderer. This class by default creates a DatumFormatter for the tickDescriptor it receives, and then uses the grannyFormat method to get the label. This object is useful as-is, but provides an easy way to get complex labels (e.g. TCAs) by overriding init and getLabel.
