vue3使用echarts，使用Echarts 后台数据已经获取  如何渲染到视图层？

 const echartInit6 = () => {

axios({

url: "/getradardata/",


data: {}


}).then(back => {


data = back.data;//不清楚dback.ata是什么结构,需要变成数组

chart_6.setOption(option,true);//渲染

}).catch(error => console.log(error, "加载失败"));


}

不知道你的back.data是啥类型

axios({
   url: "/getradardata/",
   data: {}
}).then(back => {   
   console.log(back.data);
    // 对back.data 进行处理变成[value1,value2,...]的格式
    let arr = []
    back.data.forEach(i => arr.push(i.value))
    option.series[0].data = arr
    // 赋值后重新绘制图表
    chart_6.setOption(option, true);

}).catch(error => console.log(error, "加载失败"));

数据已经console出来，不知道如何渲染在视图层，求救

这个是前面打印出来的
