Examples of XYStepRenderer

org.jfree.chart.renderer.xy.XYStepRenderer
Line/Step item renderer for an {@link XYPlot}. This class draws lines between data points, only allowing horizontal or vertical lines (steps). The example shown here is generated by the XYStepRendererDemo1.java program included in the JFreeChart demo collection:
