In the first two days, you need to draw an eckarts chart. Click the buttons of the previous week and the next week to get the data of the chart.
I have been looking for it on the Internet for a long time and found it written by the blogger. It's super. I changed it and wrote it in vue for later use.

// Get last week, this week, and next week's time
    getDates(date) {
      var year = date.getFullYear() + '-'
      var month = ((date.getMonth() + 1) + '-').length === 2 ? ('0' + (date.getMonth() + 1) + '-') : (date.getMonth() + 1) + '-'
      var day = (date.getDate() + '').length === 1 ? ('0' + date.getDate()) : date.getDate()
      this.timeStamp.push(year + month + day)
      return year + month + day
    },
    addDate(date, n) {
      date.setDate(date.getDate() + n)
      return date
    },
    setDate(date) {
      this.timeStamp = []
      var week = date.getDay() - 1
      date = this.addDate(date, week * -1)
      this.currentFirstDate = new Date(date)
      for (var i = 0; i < 7; i++) {
        this.getDates(i === 0 ? date : this.addDate(date, 1)) // Monday starts
      }
    },
    // Click previous week
    lastWeek() {
      this.setDate(this.addDate(this.currentFirstDate, -7))
      this.getGraphChartData(this.timeStamp[0], this.timeStamp[6])
    },
    // This week
    onWeek() {
      this.setDate(new Date())
      this.getGraphChartData(this.timeStamp[0], this.timeStamp[6])
    },
    // Next week
    nextWeek() {
      this.setDate(this.addDate(this.currentFirstDate, 7))
      this.getGraphChartData(this.timeStamp[0], this.timeStamp[6])
    },

The definition written in return:

      // Initial time to click last week next week button
      currentFirstDate: new Date(),
      // Returns a collection of one week's time
      timeStamp: []

In addition, there is a method to calculate the first five minutes and the next few minutes according to a certain time:

        // startTime is the standard time format, ex: 2019-04-23 00:00:00
        var date = new Date(startTime.replace(/-/g, '/'))
        // Standard time to timestamp
        var time = date.getTime()
        // Five minutes before calculation
        var time1 = time - 1000 * 60 * 5
         // 15 minutes after calculation
        var time2 = time + 1000 * 60 * 15
        // Time stamp converted to standard time
        var date1 = this.getTime(time1)
        var date2 = this.getTime(time2)

this.getTime method for standard time:

// Change time format
export function getTime(date) {
  var dateStr = ''
  date = new Date(date)
  var yy = date.getFullYear()
  var mm = parseInt(date.getMonth()) + 1
  var dd = parseInt(date.getDate())
  var hh = date.getHours()
  var min = date.getMinutes()
  var ss = date.getSeconds()
  if (mm < 10) {
    mm = '0' + mm
  }
  if (dd < 10) {
    dd = '0' + dd
  }
  if (hh < 10) {
    hh = '0' + hh
  }
  if (min < 10) {
    min = '0' + min
  }
  if (ss < 10) {
    ss = '0' + ss
  }
  dateStr = yy.toString() + '-' + mm + '-' + dd + ' ' + hh + ':' + min + ':' + ss
  return dateStr
}

Conclusion.
