JFreechart 绘制闭合曲线

在网上搜了不少，但实现总是感觉有点难受，无奈还是要看API

?

private static XYDataset createDataset(List<DataModel> data) {XYSeriesCollection xyseriescollection = new XYSeriesCollection(); // 再用XYSeriesCollection添加入XYSeriesfor (DataModel d : data) {XYSeries xyseries = new XYSeries(d.getLabel(),false); // 先产生XYSeries 对象for (Point point : d.getDataList()) {xyseries.add(point.getX(), point.getY());}if(d.getDataList().size()>0){Point point = d.getDataList().get(0);xyseries.add(point.getX(), point.getY());}xyseries.setNotify(false);System.out.println(xyseries.getAutoSort());xyseriescollection.addSeries(xyseries);}return xyseriescollection;}

主要为XYSeries的构造函数，第二个参数为是否自动排序，设为false 万事大吉。
