【筆記2】laravel數據統計繪圖（今天、7天、30天數據）

開發小筆記：按照時段統計今天、7天、30天的數據

1. 前端vue

使用vue-highcharts

<highcharts :options="options"></highcharts>

data() {
    return {
      options: {
        title: {
          text: ''
        },
        xAxis: {
          categories: []
        },
        yAxis: {
          title: {
            text: ''
          },
          plotLines: [{
            value: 0,
            width: 1,
            color: '#808080'
          }]
        },
        legend: {
          layout: 'horizontal',
          align: 'center',
          verticalAlign: 'bottom',
          borderWidth: 0
        },
        credits: {
          enabled: false   // 去掉highcharts商標
        },
        series: []
      }
    }
  },

請求數據處理：

getTimingHistoryAct(time) {
      getTimingHistory(time).then(response => {
        const curHour = new Date().getHours()
        const hoursArr = []
        const dayArr = []
        const seriesData = []
        switch (time) {
          case 1:
            seriesData.length = 0
            for (let i = 0; i <= curHour; i++) {
              hoursArr.push(i < 10 ? '0' + i : '' + i)
              seriesData[i] = 0
            }
            this.options.xAxis.categories = hoursArr.map(x => x + ':00')
            response.data.forEach(record => {
              const index = hoursArr.indexOf(record.hour)
              if (index > -1) {
                seriesData[index] = record.count
              }
            })
            break
          case 7:
            seriesData.length = 0
            for (let i = 0; i < 7; i++) {
              const ymd = new Date(new Date() - 24 * 60 * 60 * 1000 * i).toLocaleString().split(' ')[0]
              const ymdarr = ymd.split('/')
              if (ymdarr[1] * 1 < 10) {
                ymdarr[1] = '0' + ymdarr[1]
              }
              if (ymdarr[2] * 1 < 10) {
                ymdarr[2] = '0' + ymdarr[1]
              }
              seriesData[i] = 0
              dayArr.unshift(ymdarr.join('-'))
            }
            this.options.xAxis.categories = dayArr.map(x => x.substr(5))
            response.data.forEach(record => {
              const index = dayArr.indexOf(record.date)
              if (index > -1) {
                seriesData[index] = record.count
              }
            })
            break
          case 30:
            // 同7天
            break
        }
        this.options.series = [{
          name: '商品點擊',
          data: seriesData
        }]
      })
    },
