echarts绘制地图所用的json文件如何修改geometry.coordinates

echarts绘制地图所用的json文件如何修改geometry.coordinates属性；

现阶段我正在学习echarts绘制地图；
我使用的是本地json、js文件通过echarts插件绘制的。但是在绘制内蒙古 - 呼伦浩特市的时候发现与百度地图上的地图区域不太对应，
但是百度地图api里获取到的地理坐标是116.401487, 40.039207;116.396889, 40.043107;116.397532, 40.047478;116.377657, 40.050901这种形式；
而js或json里的coordinates属性（地理坐标）是："@@R@ZNJBbE\\FpGnARD\\TPDL@XEL@jRJH\\^JHJDLD`@^AfIxAH@JHDDNBXCV@ZJ~PL]LIvKRKTQHELCTADAJIreFEDGHANAHBXFL@LCNMnWDIAG@KKK@K@GJU@A_EIECEBKAKBCPMNE†UPMJG^"
这种的字符串形式。

弄了12个小时了，也没找到转换方法，用数字坐标形式，绘制的图形不太对。

有哪路大神能够指点一下，仅限于echarts实现。非常感谢

同求次方法啊~~求大神指点

[囧]

直接用没加密的数据就行了

<script type="text/javascript">
	var mapdata = {"type": "FeatureCollection", "features": [{"type":"Feature","properties":{"name":"丰台区","id":"110106"},"geometry":{"type":"MultiPolygon","coordinates":[[[[116.317345,39.8938430000001],[116.321324492188,39.8769472480469],[116.35845828125,39.8653823066407],[116.377345,39.873843],[116.39634890625,39.8501113105469],[116.411793242188,39.8693959785156],[116.437345,39.873843],[116.454151640625,39.8484108710938],[116.427345,39.833843],[116.421881132813,39.8293056464844],[116.407515898438,39.8120082832032],[116.431300078125,39.7922487617188],[116.369420195313,39.7793056464844],[116.352808867188,39.7993056464844],[116.32748171875,39.8083803535157],[116.302413359375,39.7677419257813],[116.284703398438,39.7890627265625],[116.247345,39.793843],[116.2157825,39.8279079414063],[116.192530546875,39.778637921875],[116.162877226563,39.7798122382813],[116.152535429688,39.7686525703125],[116.1217590625,39.7590334296875],[116.122545195313,39.7788430000001],[116.122125273438,39.7894289375001],[116.085533476563,39.7879787421875],[116.072535429688,39.8290334296875],[116.047345,39.843843],[116.05388796875,39.8544655585938],[116.131158476563,39.8800307441406],[116.157345,39.883843],[116.210953398438,39.8771450019531],[116.231793242188,39.8893959785157],[116.247345,39.8938430000001],[116.292506132813,39.8882009101563],[116.317345,39.8938430000001]]]]}}]};

你需要判断他们用的是什么坐标系。 参考下面这个坐标系转换 https://www.cnblogs.com/yesicoo/p/4668642.html
