Examples of org.jfree.chart.renderer.xy.StandardXYItemRenderer

org.jfree.chart.renderer.xy.StandardXYItemRenderer
Standard item renderer for an {@link XYPlot}. This class can draw (a) shapes at each point, or (b) lines between points, or (c) both shapes and lines.
This renderer has been retained for historical reasons and, in general, you should use the {@link XYLineAndShapeRenderer} class instead.
