Examples of net.sf.jasperreports.engine.JRChartDataset

net.sf.jasperreports.engine.JRChartDataset
Datasets are used to represent the actual data needed to generate a chart. The dataset structure may vary with each chart type. This is the superinterface for all datasets and contains common dataset properties. @author Teodor Danciu (teodord@users.sourceforge.net) @version $Id: JRChartDataset.java 3033 2009-08-27 11:46:22Z teodord $
