1.安装echarts依赖
npm install echarts -S
或者使用国内的淘宝镜像:
安装
npm install -g cnpm --registry=https://registry.npm.taobao.org
使用
cnpm install echarts -S
2.创建图表
全局引入
main.js
// 引入echarts import echarts from ‘echarts‘ Vue.prototype.$echarts = echarts
Hello.vue
<div id="myChart" :style="{width: ‘300px‘, height: ‘300px‘}"></div>
3.mounted 中调用 (mounted 是 vue 的生命周期,表示挂载完毕,html 已经渲染)
mounted(){
this.$nextTick(function() {
this.drawPie(‘myChart‘)
})
}
4.组件
<template>
<!--为echarts准备一个具备大小的容器dom-->
<div id="myChart" style="width:300px;height:300px;"></div>
</template>
<script>
export default {
name: ‘‘,
data () {
return {
charts: ‘‘,
opinion:[‘直接访问‘,‘邮件营销‘,‘联盟广告‘,‘视频广告‘,‘搜索引擎‘],
opinionData:[
{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‘}
]
}
},
methods:{
drawPie(id){
this.charts = $echarts.init(document.getElementById(id));
this.charts.setOption({
tooltip: {
trigger: ‘item‘,
formatter: ‘{a}<br/>{b}:{c} ({d}%)‘
},
legend: {
orient: ‘vertical‘,
x: ‘left‘,
data:this.opinion
},
series: [
{
name:‘访问来源‘,
type:‘pie‘,
radius:[‘50%‘,‘70%‘],
avoidLabelOverlap: false,
label: {
normal: {
show: false,
position: ‘center‘
},
emphasis: {
show: true,
textStyle: {
fontSize: ‘30‘,
fontWeight: ‘blod‘
}
}
},
labelLine: {
normal: {
show: false
}
},
data:this.opinionData
}
]
})
}
},
//调用
mounted(){
this.$nextTick(function() {
this.drawPie(‘myChart‘)
})
}
}
</script>
<style scoped>
* {
margin: 0;
padding: 0;
list-style: none;
}
</style>
