}  

运行效果如图：

部分代码：

[java] view plain copy
DateFormat df=new SimpleDateFormat("yyyy年MM月");  
   NumberFormat nf= NumberFormat.getNumberInstance();  
   StandardXYToolTipGenerator toolg=new StandardXYToolTipGenerator(StandardXYToolTipGenerator.DEFAULT_TOOL_TIP_FORMAT,df,nf);  
     
   renderer.setToolTipGenerator(toolg);  

加上代码可以显示对应的图点

[java] view plain copy
XYLineAndShapeRenderer xylineandshaperenderer = (XYLineAndShapeRenderer)_xyplot.getRenderer();  
//设置网格背景颜色  
  _xyplot.setBackgroundPaint(Color.white);  
//设置网格竖线颜色  
  _xyplot.setDomainGridlinePaint(Color.pink);  
//设置网格横线颜色  
  _xyplot.setRangeGridlinePaint(Color.pink);  
//设置曲线图与xy轴的距离  
  _xyplot.setAxisOffset(new RectangleInsets(0D, 0D, 0D, 10D));  
//设置曲线是否显示数据点  
xylineandshaperenderer.setBaseShapesVisible(true);  
//设置曲线显示各数据点的值
