• 利用Highcharts制作web图表学习(二)


        最近中海油的项目需要用到图表展示数据,最近还是一直边学习边开发,今天做了一个展示,炼化厂加热炉效率展示的柱状图,把代码贴出来,大家指点一下互相学习,我是通过数组给Highcharts绑定的值,感觉这样做有点麻烦而且不灵活,大家有比较好的建议可以帮我看下,我引用了三个js,可以把本地的js注释掉用这些
    <script type="text/javascript" src="http://cdn.hcharts.cn/highcharts/highcharts.js"></script>
      <script type="text/javascript" src="http://cdn.hcharts.cn/highcharts/exporting.js"></script>
     <script type="text/javascript" src="http://cdn.hcharts.cn/jquery/jquery-1.8.3.min.js"></script>
    exporting.js是用来将图表导出成你想要的格式。
    源码如下:
