如何根据两个数组获取到echart所需的x轴，y轴数据

Question

接口一返回的数组如：

接口二返回的数组如：

上面两个数组均有可能为空的情况

期待得到的数据(综合数据)：
xData: ["巡检班A","巡检班B","ceshi"]
yData1: [28,68,16]
yData2: [3,5,0]

假如接口一返回的是空数组的话，得到的数据:
xData: ["维修班A","巡检班B","巡检班A"]
yData1: [0,0,0]
yData2: [4,5,3]

Answer 1

不知道你是不是想要这种的

        var data1=[
            {ins:15,user:'巡检版1'},
            {ins:25,user:'巡检版2'},
            {ins:35,user:'巡检版3'},
        ]
        var data2=[
            {user:'巡检版1',com:1},
            {user:'巡检版2',com:2},
            {user:'巡检版3',com:3},
        ]
        let xAxisData1 = data1.map(v => v.user);
        let xAxisData2 = data2.map(v => v.user);
        let yData1 = data1.map(v => v.ins);
        let yData2 = data2.map(v => v.com);
        if(data1.length==0){
            data2.map(item=>{
                yData1.push(0)
            })
        }
        xAxisData1.push.apply(xAxisData1,xAxisData2);
        xAxisData1=new Set(xAxisData1);
        console.log(xAxisData1,yData1,yData2)

如果数组data1为空时结果如下图：
