本文實例為大家分享了vue實現(xiàn)可按時間查詢的折線圖的具體代碼，供大家參考，具體內(nèi)容如下

1.vue前端

//查詢條件<template><el-date-picker v-model='listQuery.toptime' :picker-options='pickerOptions' type='daterange' clearable range-separator='至' start-placeholder='開始日期' end-placeholder='結(jié)束日期'/> <el-select v-model='listQuery.xAxis' placeholder='統(tǒng)計粒度' clearable > <el-option v-for='(item, index) in xAxisList' :key='index' :label='item.value' :value='item.id' /> </el-select>//折線圖 <el-card class='box-card'> <div slot='header' class='clearfix'> <span>折線圖</span> </div> <div : /> </el-card></template>

2.對應(yīng)script代碼

// 引入基本模板const echarts = require(’echarts/lib/echarts’)// 引入柱狀圖組件require(’echarts/lib/chart/bar’)require(’echarts/lib/chart/pie’)// 引入提示框和title組件require(’echarts/lib/component/tooltip’)require(’echarts/lib/component/title’)require(’echarts/lib/component/legend’)export default {data() { return { listQuery: { page: 0, limit: 20, toptime: null, xAxis: null }, XList: [], XListName: ’’, YList: [], YListName: ’’, xAxisList: [ { id: 1, value: ’年’ }, { id: 2, value: ’月’ }, { id: 3, value: ’周’ } ], temp: { id: undefined, } } }, methods: { handleFilter1() { const listQueryData = Object.assign({}, this.listQuery) if (listQueryData.toptime !== null) { listQueryData.toptime = JSON.stringify(this.listQuery.toptime) } else if (listQueryData.toptime === null) { const end = new Date() const start = new Date() start.setTime(start.getTime() - 3600 * 1000 * 24 * 7)//默認按周查詢 this.listQuery.toptime = [start, end] listQueryData.toptime = JSON.stringify([start, end]) } switch (listQueryData.xAxis) { case 1: { const end = new Date() const start = new Date() start.setTime(start.getTime() - 3600 * 1000 * 24 * 365)//按年查詢 this.listQuery.toptime = [start, end] listQueryData.toptime = JSON.stringify([start, end]) break } case 2: { const end = new Date() const start = new Date() start.setTime(start.getTime() - 3600 * 1000 * 24 * 30)//按月查詢 this.listQuery.toptime = [start, end] listQueryData.toptime = JSON.stringify([start, end]) break } case 3: { const end = new Date() const start = new Date() start.setTime(start.getTime() - 3600 * 1000 * 24 * 7)//按周查詢 this.listQuery.toptime = [start, end] listQueryData.toptime = JSON.stringify([start, end]) break } } getShareTripCount(listQueryData).then(response => { this.XList = response.data.data.XList this.YList = response.data.data.YList this.YListName = response.data.data.YListName this.XListName = response.data.data.XListName this.drawLine() })},//重點drawLine() { const myChart3 = echarts.init(document.getElementById(’myChart3’)) myChart3.showLoading() // 數(shù)據(jù)加載完之前先顯示一段簡單的loading動畫 myChart3.hideLoading() // 隱藏加載動畫 // 繪制折線圖 const option = { title: { text: ’分享行程數(shù)據(jù)統(tǒng)計’, subtext: ’’ }, // tooltip: { // trigger: ’axis’ // }, legend: { data: [’總分享次數(shù)’, ’通過分享注冊用戶數(shù)’, ’今日分享次數(shù)’, ’今日通過注冊分享數(shù)’] }, // toolbox: { // show: true, // feature: { // mark: { show: true }, // dataView: { show: true, readOnly: false }, // magicType: { show: true, type: [’line’, ’bar’] }, // restore: { show: true }, // saveAsImage: { show: true } // } // }, calculable: true, xAxis: { name: this.XListName, type: ’category’, data: this.XList }, yAxis: { name: this.YListName, type: ’value’ }, series: [ { name: ’總分享次數(shù)’, type: ’line’, data: this.YList.sharenumList // markPoint: { // data: [ // { type: ’max’, name: ’最大值’ }, // { type: ’min’, name: ’最小值’ } // ] // } // markLine: { // data: [ // { type: ’average’, name: ’平均值’ } // ] // } }, { name: ’通過分享注冊用戶數(shù)’, type: ’line’, data: this.YList.shareUserRegisterList // markPoint: { // data: [ // { type: ’max’, name: ’最大值’ }, // { type: ’min’, name: ’最小值’ } // ] // } // markLine: { // data: [ // { type: ’average’, name: ’平均值’ } // ] // } }, { name: ’今日分享次數(shù)’, type: ’line’, data: this.YList.shareNumByDayList // markPoint: { // data: [ // { name: ’周最低’, value: -2, xAxis: 1, yAxis: -1.5 } // ] // } // markLine: { // data: [ // { type: ’average’, name: ’平均值’ } // ] // } }, { name: ’今日通過注冊分享數(shù)’, type: ’line’, data: this.YList.shareUserRegisterByDayList // markPoint: { // data: [ // { name: ’周最低’, value: -2, xAxis: 1, yAxis: -1.5 } // ] // } // markLine: { // data: [ // { type: ’average’, name: ’平均值’ } // ] // } } ] } myChart3.setOption(option)} }}

3.對應(yīng)后端controller代碼
