+# leaflet-echarts
+A plugin for leaflet to load echarts map and make BigData Visualization.
+## 基于leaflet 扩展echarts，使ECharts的地图可以加到leaflet上
+
+> 根据百度地图echarts的扩展改写，在事件联动这个地方以及echarts的容器与地图容器在拖动和缩放中的适应上耗费了很长时间，为了兼容echarts的map其他类型的数据又下了不少功夫。现在可以算是一个稍微完美的版本了。好的效果请在谷歌浏览器访问。~~偶尔拖拽会飘，建议拖拽的时候在没有echarts渲染数据的区域拖拽。~~ 貌似修复了！
+
+> This is a beta version,so it would have some bugs,visit it by **chrome** will be better.	~~When you want to drag the map,drag on zhe basemap without echarts data.~~	It seems that i have solved this problem.

+    	var chartsContainer=overlay.getEchartsContainer();
+    	var myChart=overlay.initECharts(chartsContainer);
+    	var option={};//这里跟百度echarts的map的option一样,the option is same as echarts map
