echarts 迁徙图 图例点击事件出错

Question

使用echarts3 做出类似迁徙图的效果如下：

但是点击图例的时候，并没有将图例所对应的系列隐藏，该系列对应的线还存在，只是该系列对应的effect特效静止不动了。

核心代码如下：
internal.bigHieChart = echarts.init($("#bigHie")[0]);

        var option = {
            tooltip: {
                trigger: "item",
                formatter: "{b}"
            },
            geo: {
                map: "xiamen",
                label: {
                    normal: {
                        show: true,
                        color: "#c1bfbf"
                    },
                    emphasis: {
                        show: true,
                        color: "#c1bfbf"
                    }
                },
                selectedMode: "single",
                roam: true,
                itemStyle: {
                    normal: {

                    },
                    emphasis: {

        internal.bigHieChart.setOption(option);

        internal.bigHieChart.on("click", function (params) {
            if (typeof params.region == "object") {
                if (params.region.selected) {
                    internal.bigHieChart.dispatchAction({
                        type: "geoSelect",
                        name: params.name
                    });
                } else {
                    internal.bigHieChart.dispatchAction({
                        type: "geoUnSelect",
                        name: params.name
                    });

                }
            }
        });

        internal.bigHieChart.on("geoselected", function (params) {
  
            req.getHieAmount(params.name, internal.setHieAmount);
        });

        internal.bigHieChart.on("geounselected", function (params) {
         
            req.getHieAmount("", internal.setHieAmount);
        });
    },
    
    
    我将图例相关代码拷贝在
    http://gallery.echartsjs.com/editor.html?c=xr1XLo-V5g
    这个上面尝试图例的点击事件一切正常。
    不清楚为什么自己写的就会报错。
    求教各位，谢谢
