Interface LegendBuilder

All Known Implementing Classes:
ColorScaleLegendBuilder, StandardLegendBuilder
public interface LegendBuilder
A legend builder is responsible for creating a legend for a chart. The API has been kept to a minimum intentionally, so as not to overly constrain developers that want to implement a custom legend builder. The get/setItemFont() methods have been added for convenience because changing the font of the legend item text is a very common operation.

Classes that implement this interface should also implement java.io.Serializable if you intend to serialize and deserialize chart objects.
