		       //显示报表预览窗口

		       preview.setVisible(true);

}

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
