How the echarts radar chart shows the percentage

option = {
        tooltip: {
        },

        radar: {
            shape: "polygon",
            radius: "60%",

            ]
        }]
    }

how to display this option as a percentage in echarts. I"ve been working on it for a long time

title: { text: '' }, tooltip: { trigger: 'axis', }, legend: { x: 'center', data:['','','','',''] }, radar: [ { indicator: [ {text: '', max: 100}, {text: '', max: 100}, {text: '', max: 100}, {text: '', max: 100} ], center: ['25%','40%'], radius: 80 }, { indicator: [ {text: '', max: 100}, {text: '', max: 100}, {text: '', max: 100}, {text: '', max: 100}, {text: '', max: 100} ], radius: 80, center: ['50%','60%'], }, { indicator: (function (){ var res = []; for (var i = 1; i <= 12; iPP) { res.push({text:i+'',max:100}); } return res; })(), center: ['75%','40%'], radius: 80 } ], series: [ { type: 'radar', tooltip: { trigger: 'item', formatter: function(a){ console.log(a); var name=['','','','']; str = a.name+'<br>' var data = a.value var value = data.reduce(function(a,b){ return a+b; }) for(var i=0;i<name.length;iPP){ str += name[i]+' ' + ((data[i]/value) * 100).toFixed(2) + '% <br>' } return str } }, itemStyle: { normal: {areaStyle: {type: 'default'}}, label: { show: true, position: 'top', } }, data: [ { value: [60,73,85,40], name: '' } ] }, { type: 'radar', radarIndex: 1, data: [ { value: [85, 90, 90, 95, 95], name: '' }, { value: [95, 80, 95, 90, 93], name: '' } ] }, { type: 'radar', radarIndex: 2, itemStyle: {normal: {areaStyle: {type: 'default'}}}, data: [ { name: '', value: [2.6, 5.9, 9.0, 26.4, 28.7, 70.7, 75.6, 82.2, 48.7, 18.8, 6.0, 2.3], }, { name:'', value:[2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 35.6, 62.2, 32.6, 20.0, 6.4, 3.3] } ] } ]
