1.安裝echarts依賴
npm install echarts -S
或者使用國內的淘寶映象:
安裝
npm install -g cnpm --registry=https://registry.npm.taobao.org
使用
cnpm install echarts -S
2.建立圖表
全域性引入
main.js
// 引入echarts
import echarts from 'echarts'
Vue.prototype.$echarts = echarts
Hello.vue
<div id="myChart" :style="{width: '300px', height: '300px'}"></div>
3.mounted 中呼叫 (mounted 是 vue 的生命週期,表示掛載完畢,html 已經渲染)
mounted(){
this.$nextTick(function() {
this.drawPie('myChart')
})
}
4.元件
<template>
<!--為echarts準備一個具備大小的容器dom-->
<div id="myChart" style="width:300px;height:300px;"></div>
</template>
<script>
export default {
name: '',
data () {
return {
charts: '',
opinion:['直接訪問','郵件營銷','聯盟廣告','視訊廣告','搜尋引擎'],
opinionData:[
{value:335, name:'直接訪問'},
{value:310, name:'郵件營銷'},
{value:234, name:'聯盟廣告'},
{value:135, name:'視訊廣告'},
{value:1548, name:'搜尋引擎'}
]
}
},
methods:{
drawPie(id){
this.charts = $echarts.init(document.getElementById(id));
this.charts.setOption({
tooltip: {
trigger: 'item',
formatter: '{a}<br/>{b}:{c} ({d}%)'
},
legend: {
orient: 'vertical',
x: 'left',
data:this.opinion
},
series: [
{
name:'訪問來源',
type:'pie',
radius:['50%','70%'],
avoidLabelOverlap: false,
label: {
normal: {
show: false,
position: 'center'
},
emphasis: {
show: true,
textStyle: {
fontSize: '30',
fontWeight: 'blod'
}
}
},
labelLine: {
normal: {
show: false
}
},
data:this.opinionData
}
]
})
}
},
//呼叫
mounted(){
this.$nextTick(function() {
this.drawPie('myChart')
})
}
}
</script>
<style scoped>
* {
margin: 0;
padding: 0;
list-style: none;
}
</style>
