       JFreeChart chart = ChartFactory.createTimeSeriesChart(
              String title,    // 图标题
                 String timeAxisLabel,   //x 轴标题
                 String valueAxisLabel,  //y 轴标题

                 boolean legend,          // 是否显示图例
                 boolean tooltips,        // 是否显示 tooltip

时序图的 Plot 对象是 XYPlot 类型。 XYPlot 对象的 x 轴是 DateAxis 对象， y 轴是 NumberAxis 对象，绘制单元是 XYLineAndShapeRenderer 对象，数据源是 XYDataset 对象。

   1. //Plot 对象的获取操作：  
   2. XYPlot plot = (XYPlot) chart.getPlot();  
   3. //X 轴对象的获取操作：  
   4. DateAxis xAxis = (DateAxis) plot.getDomainAxis();  
   5. //Y 轴对象的获取操作：  
   6. NumberAxis yAxis =(NumberAxis) plot.getRangeAxis();  
   7. //Renderer 对象的获取操作：  
   8. XYItemRenderer renderer= plot.getRenderer();  

//Plot 对象的获取操作：
XYPlot plot = (XYPlot) chart.getPlot();
//X 轴对象的获取操作：
DateAxis xAxis = (DateAxis) plot.getDomainAxis();
//Y 轴对象的获取操作：
NumberAxis yAxis =(NumberAxis) plot.getRangeAxis();
//Renderer 对象的获取操作：
XYItemRenderer renderer= plot.getRenderer();





时序图可以接受一切 XYDataset 类型的数据源，下面讲解一下常用的 XYDataset 类型 TimeSeriesCollection 的使用方式。

   1. //实例化：  
   2. TimeSeriesCollection dataset=new TimeSeriesCollection();  
   3. //添加数据操作：  
   4. dataset. addSeries(TimeSeries); // 后面讲解 TimeSeries 对象  
   5. //删除数据操作：  
   6. dataset. removeSeries(int index);  
   7. //查询数据操作 :  
   8. dataset. getSeries(int series);  

//实例化：
TimeSeriesCollection dataset=new TimeSeriesCollection();
//添加数据操作：
dataset. addSeries(TimeSeries); // 后面讲解 TimeSeries 对象
//删除数据操作：
dataset. removeSeries(int index);
//查询数据操作 :
dataset. getSeries(int series);





TimeSeries 对象操作
Java代码  收藏代码

   1. //实例化：  
   2. TimeSeries ts=TimeSeries(String name, Class timePeriodClass);  
   3. //增加数据操作：  
   4. ts. add(RegularTimePeriod period, double value);   
   5. //删除数据操作：  
   6. ts. delete(RegularTimePeriod period);     
   7. //修改数据操作：  
   8. ts. update(RegularTimePeriod period, Number value);  
   9. //查询数据操作：  
  10. ts. getValue(RegularTimePeriod period);  

//实例化：
TimeSeries ts=TimeSeries(String name, Class timePeriodClass);
//增加数据操作：
ts. add(RegularTimePeriod period, double value); 
//删除数据操作：
ts. delete(RegularTimePeriod period);   
//修改数据操作：
ts. update(RegularTimePeriod period, Number value);
//查询数据操作：
ts. getValue(RegularTimePeriod period);



类 RegularTimePeriod 是 JFreeChart 提供的时间模板类，它有很多具体的时间类，比如： Minute 、 Second 、 Hour 、 Day…… 等，不再详述
