最近工作中需要用到echarts，由于项目是用的vue-cli开发的。在网上搜到vue中合成了vue-echarts，但是不想使用vue中规定好的数据格式，于是就自己做了一个vue项目引用原生echarts的简单demo，实现过程如下：用了两种实现方式
准备工作
1、安装echarts依赖
控制台输入：npm install echarts --save
2、全局引入
main.js中引入
import echarts from 'echarts' Vue.prototype.$echarts = echarts
创建图表
第一种创建方式
在一个.vue文件中引入多张图表
创建WelcomePage.vue
<template> <div> <h2>第一种在vue中使用echart的方式</h2> <div class="charts"> <div id="barGraph" ></div> </div> <div class="charts"> <div id="pieGraph" ></div> </div> </div> </template>
<script>
// 引入基本模板,按需加载
let echarts = require('echarts/lib/echarts');
// 引入柱状图
require('echarts/lib/chart/bar');
// 引入柱状图
require('echarts/lib/chart/pie');
require('echarts/lib/component/tooltip');
require('echarts/lib/component/title');
export default {
name: "WelcomePage",
data () {
return { }
},
mounted(){
this.drawBar();
this.drawPie();
},
methods:{
drawBar(){
// 基于dom，初始化echarts实例
let barGraph = echarts.init(document.getElementById('barGraph'));
// 绘制图表
barGraph.setOption({
title: {
text: '全年产量趋势图',
left: 'center'
},
tooltip: {
trigger: 'item',
formatter: '{a} <br/>{b} : {c}'
},
legend: {
left: 'center',
data: ['本年', '上年'],
bottom:0
},
xAxis: {
type: 'category',
name: 'x',
splitLine: {show: false},
data: ['一月', '二月', '三月', '四月', '五月', '六月', '七月', '八月', '九月', '十月', '十一月', '十二月']
},
grid: {
left: '1%',
right: '2%',
bottom: '8%',
containLabel: true
},
yAxis: {
type: 'category',
name: 'y',
splitLine: {show: true},
data:['10%','20%','30%','40%','50%','60%','70%','80%','90%','100%']
},
series: [
{
name: '本年',
type: 'line',
data: [0.8, 0.98, 0.96, 0.27, 0.81, 0.47, 0.74, 0.23, .69, 0.25, 0.36, 0.56]
},
{
name: '上年',
type: 'line',
data: [1, 0.2, 0.4, 0.8, 0.16, 0.32, 0.64, 1.28, 5.6, 0.25, 0.63, 0.65, 0.12]
},
]
})
},
drawPie(){
let pieGraph = echarts.init(document.getElementById('pieGraph'));
pieGraph.setOption({
title : {
text: '某站点用户访问来源',
subtext: '纯属虚构',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
legend: {
orient: 'vertical',
left: 'left',
data: ['直接访问','邮件营销','联盟广告','视频广告','搜索引擎']
},
series : [
{
name: '访问来源',
type: 'pie',
radius : '55%',
center: ['50%', '60%'],
data:[
{value:335, name:'直接访问'},
{value:310, name:'邮件营销'},
{value:234, name:'联盟广告'},
{value:135, name:'视频广告'},
{value:1548, name:'搜索引擎'}
],
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
})
}
}
}
</script>
实现效果如下图：
第二种实现方式（以组件的形式）
创建父组件 father.vue
<div>
<h2>{{ msg }}</h2>
<p>第二种方式：通过组件的方式进行页面渲染</p>
<div class="container" >
<bar-graph></bar-graph>
</div>
<div class="container">
<pie-graph></pie-graph>
</div>
</div>
<script>
// 引入两个子组件
import BarGraph from "./bargraph";
import PieGraph from "./piegraph";
export default {
name: "father",
components:{
BarGraph,
PieGraph,
},
data(){
return{
msg: '我是爸爸，想看我的儿子，眼睛请往下移',
}
}
}
</script>
创建子组件barGraph.vue
<div>
<p>{{ msg }}</p>
<div class="charts">
<div :id="id" ></div>
</div>
</div>
<script>
let echarts = require('echarts/lib/echarts');
// 引入柱状图
require('echarts/lib/chart/bar');
require('echarts/lib/component/tooltip');
require('echarts/lib/component/title');
// import echarts from 'echarts'
export default {
name: "bargraph",
// props:['id'], // 第一种接收父亲传过来的值的方式
props: {
id: {
type: String,
default: 'chart'
}
},
data(){
return {
msg: "我是第一个子组件--bar",
chart: null,
}
},
mounted(){
this.drawBar();
},
methods:{
drawBar(){
this.chart = echarts.init(document.getElementById(this.id));
let colors = ['#5793f3', '#d14a61', '#675bba'];
this.chart.setOption(
{
color: colors,
tooltip: {
trigger: 'axis',
axisPointer: {
type: 'cross'
}
},
grid: {
right: '20%'
},
toolbox: {
feature: {
dataView: {show: true, readOnly: false},
restore: {show: true},
saveAsImage: {show: true}
}
},
legend: {
data:['蒸发量','降水量','平均温度']
},
xAxis: [
{
type: 'category',
axisTick: {
alignWithLabel: true
},
data: ['1月','2月','3月','4月','5月','6月','7月','8月','9月','10月','11月','12月']
}
],
yAxis: [
{
type: 'value',
name: '蒸发量',
min: 0,
max: 250,
position: 'right',
axisLine: {
lineStyle: {
color: colors[0]
}
},
axisLabel: {
formatter: '{value} ml'
}
},
{
type: 'value',
name: '降水量',
min: 0,
max: 250,
position: 'right',
offset: 80,
axisLine: {
lineStyle: {
color: colors[1]
}
},
axisLabel: {
formatter: '{value} ml'
}
},
{
type: 'value',
name: '温度',
min: 0,
max: 25,
position: 'left',
axisLine: {
lineStyle: {
color: colors[2]
}
},
axisLabel: {
formatter: '{value} °C'
}
}
],
series: [
{
name:'蒸发量',
type:'bar',
data:[2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 135.6, 162.2, 32.6, 20.0, 6.4, 3.3]
},
{
name:'降水量',
type:'bar',
yAxisIndex: 1,
data:[2.6, 5.9, 9.0, 26.4, 28.7, 70.7, 175.6, 182.2, 48.7, 18.8, 6.0, 2.3]
},
{
name:'平均温度',
type:'line',
yAxisIndex: 2,
data:[2.0, 2.2, 3.3, 4.5, 6.3, 10.2, 20.3, 23.4, 23.0, 16.5, 12.0, 6.2]
}
]
}
)
}
}
}
</script>
创建pieGraph.vue
<template>
<div>
<p>{{ msg }}</p>
<div class="charts">
<div :id="id" ></div>
</div>
</div>
</template>
<script>
import echarts from 'echarts'
export default {
name: "piegraph",
props:{
id: {
type: String,
default: 'pieChart'
}
},
data(){
return{
msg: '我是第二个子组件--pie',
pieChart: null
}
},
mounted(){
this.drawPie();
},
methods: {
drawPie () {
this.pieChart = echarts.init(document.getElementById(this.id));
this.pieChart.setOption(
{
title : {
text: '某站点用户访问来源',
subtext: '纯属虚构',
x:'center'
},
tooltip : {
trigger: 'item',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
legend: {
orient: 'vertical',
left: 'left',
data: ['直接访问','邮件营销','联盟广告','视频广告','搜索引擎']
},
series : [
{
name: '访问来源',
type: 'pie',
radius : '55%',
center: ['50%', '60%'],
data:[
{value:335, name:'直接访问'},
{value:310, name:'邮件营销'},
{value:234, name:'联盟广告'},
{value:135, name:'视频广告'},
{value:1548, name:'搜索引擎'}
],
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: 'rgba(0, 0, 0, 0.5)'
}
}
}
]
}
)
}
}
}
</script>
效果实现如下：
路由文件如下：
import WelcomePage from '@/components/WelcomePage'
import Father from '@/components/father'
import BarGraph from '@/components/bargraph'
import PieGraph from '@/components/piegraph'
export default new Router({
routes: [
{
path: '/',
name: 'WelcomePage',
component: WelcomePage
},
{
path: '/father',
name: 'father',
component: Father,
children:[
{
path: '/bargraph',
name: 'bargraph',
component: BarGraph
},
{
path: '/piegraph',
name: 'piegraph',
component: PieGraph
}
]
},
]
})
