运行效果如图：

部分代码：

 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

   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
