Vue使用echarts可视化组件的方法
echarts组件官网地址:https://echarts.apache.org/examples/zh/index.html
1.找到脚手架项目所在地址,执行cnpm install echarts,安装echarts组件(脚手架的地址就是你vue项目的地址)
(E:\demo\vuepro)这是我的项目地址,vuepro为项目名
2.按需导入,以加快打开速度
//引入echarts组件 import echarts from "echarts" // 引入基本模板 let echart = require('echarts/lib/echarts') // 引入柱状图组件 require('echarts/lib/chart/bar') // 引入提示框和title组件 require('echarts/lib/component/tooltip') require('echarts/lib/component/title')
3.准备div标签 容纳报表图形
div的 id用于绑定echarts插件
<div id="chart" style="width: 50%; height: 400px;"> </div>
4.script标签的内容
//引入echarts组件 import echarts from "echarts" // 引入基本模板 let echart = require('echarts/lib/echarts') // 引入柱状图组件 require('echarts/lib/chart/bar') // 引入提示框和title组件 require('echarts/lib/component/tooltip') require('echarts/lib/component/title') export default{ name: 'App', data(){ return{ chartColumn:null } }, methods:{ initData(){ let dt=document.querySelector("#boss") this.chartColumn=echart.init(dt) this.chartColumn.setOption( //Examples中的模板 ) } }, mounted(){ this.initData() } }
为了方便大家的使用,我在这里放一个在Vue中引入echarts可视化组件的完整模板,大家直接复制使用即可
<template> <div id="boss" style="width: 500px;height: 500px;"> </div> </template> <script> //引入echarts组件 import echarts from "echarts" // 引入基本模板 let echart = require('echarts/lib/echarts') // 引入柱状图组件 require('echarts/lib/chart/bar') // 引入提示框和title组件 require('echarts/lib/component/tooltip') require('echarts/lib/component/title') export default{ name: 'App', data(){ return{ chartColumn:null } }, methods:{ initData(){ let dt=document.querySelector("#boss") this.chartColumn=echart.init(dt) this.chartColumn.setOption( //Examples中模板 ) } }, mounted(){ this.initData() } } </script> <style> </style>
案例:
<template> <div id="boss" style="width: 500px;height: 500px;"> </div> </template> <script> import echarts from "echarts" // 引入基本模板 let echart = require('echarts/lib/echarts') // 引入柱状图组件 require('echarts/lib/chart/bar') // 引入提示框和title组件 require('echarts/lib/component/tooltip') require('echarts/lib/component/title') export default{ name: 'App', data(){ return{ chartColumn:null } }, methods:{ initData(){ let dt=document.querySelector("#boss") this.chartColumn=echart.init(dt) this.chartColumn.setOption( //以下为echarts可视化组件 { tooltip: { trigger: 'axis', axisPointer: { // Use axis to trigger tooltip type: 'shadow' // 'shadow' as default; can also be 'line' or 'shadow' } }, legend: { data: ['Direct', 'Mail Ad', 'Affiliate Ad', 'Video Ad', 'Search Engine'] }, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, xAxis: { type: 'value' }, yAxis: { type: 'category', data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun'] }, series: [ { name: 'Direct', type: 'bar', stack: 'total', label: { show: true }, emphasis: { focus: 'series' }, data: [320, 302, 301, 334, 390, 330, 320] }, { name: 'Mail Ad', type: 'bar', stack: 'total', label: { show: true }, emphasis: { focus: 'series' }, data: [120, 132, 101, 134, 90, 230, 210] }, { name: 'Affiliate Ad', type: 'bar', stack: 'total', label: { show: true }, emphasis: { focus: 'series' }, data: [220, 182, 191, 234, 290, 330, 310] }, { name: 'Video Ad', type: 'bar', stack: 'total', label: { show: true }, emphasis: { focus: 'series' }, data: [150, 212, 201, 154, 190, 330, 410] }, { name: 'Search Engine', type: 'bar', stack: 'total', label: { show: true }, emphasis: { focus: 'series' }, data: [820, 832, 901, 934, 1290, 1330, 1320] } ] } //组件到此结束 ) } }, mounted(){ this.initData() } } </script> <style> </style>
