• HighChars 之曲线报表和柱状报表


    第一章介绍了highchars 的基本情况和一个饼型报表。

    接下来我们做一个曲线报表和柱状报表,就当做一个代码的备份。具体的步骤就不说了。可以参见第一篇文章。

    代码如下:

    package com.highcharts;
    
    import java.io.IOException;
    
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    /**
     * line_base 报表 和柱状报表
     * */
    public class Line_basic extends HttpServlet {
    	 
    	private static final long serialVersionUID = 7255053394404579739L;
        /**
         * line_basic  曲线图报表
         * 把相应的数据在后台组装好,在前台显示就好。
         * 数据大小的x作标会相应的变化。
         */
    
    	@Override
    	protected void doGet(HttpServletRequest req, HttpServletResponse resp)
    			throws ServletException, IOException {
    		String categories="['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun','Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec','一','二','三','四','五','一']";
    		req.setAttribute("categories",categories);
    		System.out.println(categories);
    		
    		String dataString ="{name: 'Tokyo',data: [7.0, 6.9, 9.5, 14.5, 18.2, 21.5, 25.2, 26.5, 23.3, 18.3, 13.9, 9.6, 9.1,7.0, 6.9, 9.5, 14.5, 18.2]}," +
    							"{name: 'New York',data: [-0.2, 0.8, 5.7, 11.3, 17.0, 22.0, 24.8, 24.1, 20.1, 14.1, 8.6, 2.5, 9.2,-0.2, 0.8, 5.7, 11.3,9.5 ]},"+  
    							"{name: 'Berlin',data: [-9, 0.6, 3.5, 8.4, 13.5, 17.0, 18.6, 17.9, 14.3, 9.0, 3.9, 1.0, 9.3,-9, 0.6, 3.5, 8.4, 13.5]}, " +
    							"{name: 'London', data: [3.9, 4.2, 5.7, 8.5, 11.9, 15.2, 17.0, 16.6, 14.2, 10.3, 6.6, 4.8, 9.4,3.9, 4.2, 5.7, 8.5, 11.9]}";
    		req.setAttribute("data",dataString);
    		System.out.println(dataString);
    		req.getRequestDispatcher("/line_basic.jsp").forward(req,resp);
    	}
    
     
    	@Override
    	protected void doPost(HttpServletRequest req, HttpServletResponse resp)
    			throws ServletException, IOException {
    		this.doGet(req, resp);
    	}
    
    }

                    plotLines: [{
                        value: 0,

                },
                tooltip: {
                    formatter: function() {
                            return '<b>'+ this.series.name +'</b><br/>'+
                            this.x +': '+ this.y +'°C';

                },
                legend: {
                    layout: 'vertical',
                    align: 'right',
                    verticalAlign: 'top',
                    x: -10,
                    y: 100,
                    borderWidth: 0
                },
              // 可以不弹出提示 直接展示数据 开始
    	           plotOptions: {
    	                line: {
    	                    dataLabels: {
    	                        enabled: true
    	                    },
    	                    enableMouseTracking: false
    	                }
    	            },
                // 可以不弹出提示 直接展示数据 结束
                
                series: [${data}]
            });
        });
        
    });
    		</script>
    	</head>
    	<body>
    
    
    <div id="container" style="min- 400px; height: 400px; margin: 0 auto"></div>
    ${categories}<br/>
    ${data}
    	</body>
    </html>
    

    结果图:

    当加上 plotoptions 时,会有数据显示出来。而不会有弹出层。

    如果把类型改成:

    chart: {
      renderTo: 'container',
      type: 'column'
      }

    就把变成柱状图:



    具体的那些参数据可以按照示例修改。
