ilog.views.chart.graphic

Interface IlvDataAnnotation

All Known Implementing Classes:

IlvDataLabelAnnotation, IlvDefaultDataAnnotation

public interface IlvDataAnnotation

Represents a graphical annotation that can be associated with a data point. Annotations can be specified either globally or individually:

• To associate an annotation with all the data points of a data set, use the ilog.views.chart.IlvChartRenderer#setAnnotation(IlvDataSet, IlvDataAnnotation) method.
• To associate an annotation with a specific data point, use the ilog.views.chart.IlvChartRenderer#setAnnotation(IlvDataSet, int, IlvDataAnnotation) method.

Note: Annotations don't notify their changes automatically. If you are making changes to an annotation that is being used by a renderer, you have to invoke renderer.triggerChange(ChartRendererEvent.ANNOTATION_CHANGED) in order to ensure that the chart gets updated.
