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);
}
}

// 可以不弹出提示 直接展示数据 开始
plotOptions: {

<body>
<div id="container" style="min-width: 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。
