本文主要是介绍Echarts图表和timeline时间轴的使用,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
option单独放在一个js文件中
export const barOptionMobiSub = {baseOption: {timeline: {axisType: 'category',realtime: true,autoPlay: false,symbolSize: 8,orient: 'vertical',inverse: true,// z: 2,top: 30,right: 'auto',bottom: 10,left: '80%',data: [],label: {interval: 0,color: '#1781bf'},// symbol: 'roundRect',symbol: 'pin',lineStyle: {show: true,color: '#1781bf',width: 1,type: 'dotted'},controlStyle: {showPlayBtn: false,showPrevBtn: false,showNextBtn: false},itemStyle: {color: '#1781bf'},checkpointStyle: {symbol: 'none'},tooltip: {formatter: []},grid: {containLabel: true},series: [{type: 'bar'}]}},options: [{title: {text: '',left: '30%'},legend: {data: ['累积流量', '累积耗电'],orient: 'vertical',left: 0},toolbox: {feature: {dataView: {}}},tooltip: {},xAxis: {position: 'top',axisLabel: {rotate: 45}},yAxis: {data: [],splitLine: {show: false},axisLabel: {interval: 0,rotate: -45},offset: 0,gridIndex: 0,triggerEvent: true},grid: {left: '20%',right: '20%'// bottom: 80},series: [{name: '累积流量',type: 'bar',data: [],animationDelay: function (idx) {return idx * 10}},{name: '累积耗电',type: 'bar',data: [],animationDelay: function (idx) {return idx * 10 + 100}}],animationEasing: 'elasticOut',animationDelayUpdate: function (idx) {return idx * 5}}]
}
在vue文件中导入
import { barOptionMobiSub } from '@/echartOption'
<template><div><div id="myChart" ref="myChart" :class="{hidden: isDisplay}"></div><el-scrollbar class="list"><div id="selectArea":class="{hidden: !isDisplay, active: activeName == item.name}"v-for="item of districts":key="item.id"@click="selectArea(item)"><div class="head-title" v-text="item.name" :title="item.name"></div></div></el-scrollbar><div id="myChart2" ref="myChart2" :class="{hidden: !isDisplay}"></div><divid="back":class="{hidden: !isDisplay}"@click="isDisplay = !isDisplay"style="cursor:pointer">返回上一级</div></div>
