Echart在Openlayers的应用-航班的炫光特效

概述

在前两篇文章中讲到了echart在openlayers2中的应用,地图统计图与热力图的实现,在本文中介绍openlayers中结合echart实现航班的炫光特效展示。

效果

实现代码:

1、EchartLayer

OpenLayers.Layer.EchartLayer = OpenLayers.Class(OpenLayers.Layer,
    {
        isBaseLayer : false,
        echart : null,

            echartdiv.style.cssText = "position:absolute;width:" + map.size.w + "px;height:"

            {
                scope.updateLayer(e);
            };
            map.events.register("zoomend", this, handler);

            var x = scrPt.x,
