Echarts结合百度地图API

下面的代码运用到了Echarts 和百度地图API,地图的样式自定义的。(效果图在最下边)
运用到了百度API中的自定义控件，监听事件addEventListener(),添加控件addControl(),添加覆盖物addOverlay()
移除覆盖物removeOverlay()

  //运用Echarts图标表的标准步骤首先需要初始化一个Echarts对象，可以简单理解为定义显示图标显示的位置。 <script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/jquery/jquery.js"></script><script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/echarts-all-3.js"></script><script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/extension/dataTool.min.js"></script><script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/map/js/china.js"></script><script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/map/js/world.js"></script><script type="text/javascript" src="//api.map.baidu.com/api?v=2.0&ak=nfeXoUbpxqp5FTKyxtcLkEiKNaAGpa8H"></script><script type="text/javascript" src="http://echarts.baidu.com/gallery/vendors/echarts/extension/bmap.min.js"></script><script type="text/javascript">    var dom = document.getElementById("allmap");
