达到的效果是，隐藏其他图例，只显示当前hover的图例，在emphasis中也可以配置更多的hover效果

option = {
    title: {
        text: '堆叠区域图'
    },
    tooltip: {
        trigger: 'axis',
        axisPointer: {
            type: 'cross',
            label: {
                backgroundColor: '#6a7985'
            }
        }
    },
    legend: {
        data: ['邮件营销', '联盟广告', '视频广告', '直接访问', '搜索引擎']
    },
    toolbox: {
        feature: {
            saveAsImage: {}
        }
    },
    grid: {
        left: '3%',
        right: '4%',
        bottom: '3%',
        containLabel: true
    },
    xAxis: [
        {

            boundaryGap: false,
            data: ['周一', '周二', '周三', '周四', '周五', '周六', '周日']
        }
    ],
    yAxis: [
        {
            type: 'value'
        }
    ],
    series: [
