Examples of VectorRenderer

org.jfree.chart.renderer.xy.VectorRenderer
A renderer that represents data from an {@link VectorXYDataset} by drawing aline with an arrow at each (x, y) point. The example shown here is generated by the VectorPlotDemo1.java program included in the JFreeChart demo collection:
