动态月数据集

我正在尝试为我的图表创建明智的数据数组。结合每个月的所有销售和购买价值动态月数据集

谁能帮助我获得预期的产出将会非常有帮助。我重视我与我的预期输出试图创建图表

如果可能的话，指导我一些Java脚本功能，这可以是有用的，我

var mainData = [ 
    { 
    "date": "2017-01-03", 
    "month": "JAN", 
    "sales": "200", 
    "purchase": "1000" 
    }, 
    { 
    "date": "2017-01-18", 
    "month": "JAN", 
    "sales": "800", 
    "purchase": "2500" 
    }, 
    { 
    "date": "2017-01-22", 
    "month": "JAN", 
    "sales": "400", 
    "purchase": "2100" 
    }, 
    {

    "month": "FEB",

令人困惑的是：你的数据分布在JAN，FEB和MAR上，但是你的数据分布在Q1，Q2和Q3。这是故意的吗？ – trincot

@trincot对不起我的错误，我刚刚发布了我的图表数据的一部分..更新了我的小提琴。任何方式从mainData对象获得预期的输出 – user4324324

您可以使用小提琴这个功能：

function transformData(data) { 
 
    return { 
 
     data: data.reduce ((acc, item) => { 
 
      let i = acc.months.get(item.month) || 0; 
 
      acc.data[i] = acc.data[i] || { 
 
       data: [{ 
 
        event: "sales", 
 
        inventory: [] 
 
       }, { 
 
        event: "purchase", 
 
        inventory: [] 
 
       }] 
 
      }; 
 
      acc.data[i].data[0].inventory.push({ value: item.sales }); 
 
      acc.data[i].data[1].inventory.push({ value: item.purchase }); 
 
      acc.months.set(item.month, i+1); 
 
      return acc; 
 
     }, { months: new Map, data: [] }).data 
 
    }; 
 
} 
 

 
// Input 
 
var data = [ 
 
    { 
 
    "date": "2017-01-03", 
 
    "month": "JAN", 
 
    "sales": "200", 
 
    "purchase": "1000" 
 
    }, 
 
    { 
 
    "date": "2017-01-18", 
 
    "month": "JAN", 
 
    "sales": "800", 
 
    "purchase": "2500" 
 
    }, 
 
    { 
 
    "date": "2017-01-22", 
 
    "month": "JAN", 
 
    "sales": "400", 
 
    "purchase": "2100" 
 
    }, 
 
    { 
 
    "date": "2017-02-20", 
 
    "month": "FEB", 
 
    "sales": "40", 
 
    "purchase": "90" 
 
    }, 
 
    { 
 
    "date": "2017-02-28", 
 
    "month": "FEB", 
 
    "sales": "970", 
 
    "purchase": "2100" 
 
    }, 
 
    { 
 
    "date": "2017-02-29", 
 
    "month": "FEB", 
 
    "sales": "3300", 
 
    "purchase": "2900" 
 
    }, 
 
    { 
 
    "date": "2017-03-20", 
 
    "month": "MAR", 
 
    "sales": "600", 
 
    "purchase": "900" 
 
    } 
 
]; 
 

 
// Conversion 
 
var result = transformData(data); 
 

 
// Output 
 
console.log(result);
