Interface IAnnotationSet

public interface IAnnotationSet

This class contains all annotations of the chart object. Note that annotations of other objects, such as TrendLine, HozVertLine and ControlLine, are not stored here. This class also has a method to create a new annotation for any referenced object

Method Summary

void	addAnnotation(IAnnotation anno) Adds an annotation to the chart.
java.util.Vector	getAnnotationList() Returns a list of IAnnotation objects using the whole chart as the referenced object.
IAnnotation	newAnnotation(java.lang.String text) Returns a new annotation object using the origin of the chart as the reference point.
IAnnotation	newAnnotation(java.lang.String[] text) Returns a new annotation object using the origin of the chart as the reference point.
IAnnotation	newAnnotation(java.lang.String[] text, int[] shape, java.awt.Color[] color) Returns a new annotation object using the origin of the chart as the reference point.
IAnnotation	newAnnotation(java.lang.String[] text, int[] shape, java.awt.Color[] color, IReferenceObj refObj) Returns a new annotation object with a specific referenced object.
IAnnotation	newAnnotation(java.lang.String[] text, IReferenceObj refObj) Returns a new annotation object with a specific referenced object.
IAnnotation	newAnnotation(java.lang.String text, IReferenceObj refObj) Returns a new annotation object with a specific referenced object If the value of refObj is null, the reference point is the lower-left corner of the panel
boolean	removeAnnotation(IAnnotation anno) Removes an annotation from the chart.
