echarts 饼图 引导线前的圆点怎么做的?

Question

Answer 1

series里面写两次，两次的饼图数据一样，第一次的label是不带点的文字，第二次的label只有一个点，这样就可以单独移动点了，这边有我写的一个例子
const data = {

        dataSex: [ {
            value: '202',
        }],
        dataAge: [{
            name: '中风险',
            value: '272'
        }, {
            name: '高风险',
            value: '292'
        }, {
            name: '无风险',
            value: '120'
        }, {
            name: '低风险',
            value: '42'
        }]
    };
   option = {
        color: 'rgb(193,193,193)',
        series: [
            {
                color: ['rgb(255,99,39)', 'rgb(17,95,225)','rgb(2,144,255)','rgb(252,214,88)'],
                type: 'pie',
                radius: ['60', '90'],
                center: ['50%', '40%'],
                hoverAnimation: false, //鼠标移入变大
                labelLine: {
                    normal: {
                        length: 10,
                        length2: 80,
                        lineStyle: {
                            type: 'solid'
                        }

                        formatter: (params)=>{
                            return '{b| '+params.name+'}  ' + '{c|'+params.percent.toFixed(0)+'%}'
                        },
                        borderWidth: 0,
