需要展示出一天中所有小时的数据，后端返回的数据是这样
beforData: [

  {
    "time_hours": "09", // 时间
    "approved_amount": 28068.0,
    "pass_rate": 1.0
  },
  {
    "time_hours":"10",
    "approved_amount":0.0,
    "pass_rate":0.0
  },
  {
    "time_hours":"11",
    "approved_amount":42706.0,
    "pass_rate":0.5
  },
  {
    "time_hours":"13",
    "approved_amount":0.0,
    "pass_rate":0.0
  },
  {
    "time_hours":"15",
    "approved_amount":37700.0,
    "pass_rate":0.5714285714
  },
  {
    "time_hours":"16",
    "approved_amount":0.0,
    "pass_rate":0.0
  },
  {
    "time_hours":"17",
    "approved_amount":29520.0,
    "pass_rate":0.6
  },
  {
    "time_hours":"18",
    "approved_amount":0.0,
    "pass_rate":0.0
  },{
    "time_hours":"19",
    "approved_amount":56216.0,
    "pass_rate":1.0
  },
  {
    "time_hours":"22",
    "approved_amount":5800.0,
    "pass_rate":1.0
  },
  {
    "time_hours":"23",
    "approved_amount":0.0,
    "pass_rate":0.0
  }
]

需要将缺少的小时补全，转化成
[

  {
    "time_hours": "01:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "02:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "03:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "04:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "05:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "06:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "07:00",
    "approved_amount": null,

  {

  },
  {
    "time_hours": "09:00",
    "approved_amount": 28068.0,
    "pass_rate": 1.0
  },
  {

  },
  {
    "time_hours":"11:00",

    "pass_rate":0.5
  },
  {
    "time_hours": "12:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours":"13:00",
    "approved_amount":0.0,
    "pass_rate":0.0
  },
  {
    "time_hours": "14:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours":"15:00",
    "approved_amount":37700.0,
    "pass_rate":0.5714285714
  },
  {
    "time_hours":"16:00",
    "approved_amount":0.0,
    "pass_rate":0.0
  },
  {
    "time_hours":"17:00",
    "approved_amount":29520.0,
    "pass_rate":0.6
  },
  {
    "time_hours":"18:00",
    "approved_amount":0.0,
    "pass_rate":0.0
  },{
    "time_hours":"19:00",
    "approved_amount":56216.0,
    "pass_rate":1.0
  },
  {
    "time_hours": "20:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours": "21:00",
    "approved_amount": null,
    "pass_rate": null,
  },
  {
    "time_hours":"22:00",
    "approved_amount":5800.0,
    "pass_rate":1.0
  },
  {
    "time_hours":"23:00",
    "approved_amount":0.0,
    "pass_rate":0.0
  },
  {
    "time_hours": "00:00",
    "approved_amount": null,
    "pass_rate": null,
  },
]
