已找到！

[coolwxb]

@zuifengwuchou 请问是什么方法啊

[zuifengwuchou]

@coolwxb
myChart.on('graphRoam', function (params) {
var zoom = myChart._coordSysMgr._coordinateSystems[0]._zoom;
var option = myChart.getOption();
});

[coolwxb]

@zuifengwuchou 谢谢，我去试试

[coolwxb]

@zuifengwuchou 对了 我的series type 是map类型
series: [ { type: 'map', mapType: 'china', roam: true, } ]
这种你知道要怎么监听么？我试了graphRoam和roam貌似都不好用

[zuifengwuchou]

geoRoam

[coolwxb]

@zuifengwuchou 谢谢，这回真的好使了，不过请问下这些个参数实在文档哪里能找到，我看官网3.0的文档没发现这些个参数呀

@coolwxb
在源码中找到的
