数据格式化对象数组整理成echarts想要的样子

快速的数据整理dataBefore to dataAfter

dataBefore=[{
    no:1,
    name:'a',
    value:'10'
},{
    no:1,
    name:'b',
    value:'11'
},{
    no:2,
    name:'a',
    value:'10'
},{
    no:2,
    name:'b',
    value:'10'
}]

数据整合代码

for (const item of dataBefore) {
    let b = dataAfter.find((list) => list.no === item.no);
    if (b) {
        b.name.push(item.name)
        b.value.push(item.value)
    } else {
        dataAfter.push({ no: item.no, name: [item.name], value: [item.value] })
    }
}

dataAfter=[{
    no:1,
    name:['a','b'],
    value:['10','11']
},{
    no:2,
    name:['a','b'],
    value:['10','10']
}]
