/初始化过程/
this.echarts.getZr().on('click',function (params) {

                    /*此处添加具体执行代码*/

                    //获得图表中我们想要的数据
                    var monthData=op.xAxis[0].data[xIndex];

 //将可以响应点击事件的范围内，鼠标样式设为pointer--------------------

2. that.echarts.getZr().on('mousemove',function (params) {

                var pointInPixel= [params.offsetX, params.offsetY];
                if (that.echarts.containPixel('grid',pointInPixel)) {
                    that.echarts.getZr().setCursorStyle('pointer');
                };
    });

3. that.echarts.on('mouseout', function (params) {

                var pointInPixel= [params.offsetX, params.offsetY];
                if (!that.echarts.containPixel('grid',pointInPixel)) {
                    that.echarts.getZr().setCursorStyle('default');
                };
     });
