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

org.jfree.chart.renderer.xy.XYLineAndShapeRenderer
A renderer that connects data points with lines and/or draws shapes at each data point. This renderer is designed for use with the {@link XYPlot}class. The example shown here is generated by the XYLineAndShapeRendererDemo2.java program included in the JFreeChart demo collection:

    
    return plot;
  }


  private XYItemRenderer getRouteRenderer(XYSeriesCollection solutionColl) {
    XYItemRenderer solutionRenderer = new XYLineAndShapeRenderer(true, false);   // Lines only
    for(int i=0;i<solutionColl.getSeriesCount();i++){
      XYSeries s = solutionColl.getSeries(i);
      XYDataItem firstCustomer = s.getDataItem(1);
      firstActivities.add(firstCustomer);
    }
