如下图所示表格

方法: 

//处理数据 将x y z 合并成[x,y,z]
    let dealData = (xList, yList, zList) => {
        let result = []
        for(let i = 0; i < yList.length; i++){
            for(let j = 0; j < xList.length; j++){
                result.push([xList[j],yList[i], zList[i*yList.length + j]])
            }
        }
        return result
    }
