series: [
    {
        name:'訪問來源',
        type:'pie',
        radius: ['50%', '70%'],
        avoidLabelOverlap: false,
        label: {
            normal: {
                show: true,
                position: 'inside',
                formatter:`lxjlb1z` + '%'
            },
            emphasis: {
                show: true,
                textStyle: {
                    fontSize: '30',
                    fontWeight: 'bold'
                }
            }
        },
        labelLine: {
            normal: {
                show: false
            }
        },
        data:[
            {value:335, name:'直接訪問'},
            {value:310, name:'郵件營銷'},
            {value:234, name:'聯(lián)盟廣告'},
