npm install echarts -S
或者使用淘宝的镜像
npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm install echarts -S
在main.js中引入echarts
import echarts from ‘echarts’
Vue.prototype.$echarts = echarts
使用ECharts的时候遇到了报错:
Error in mounted hook: “TypeError: Cannot read property ‘init’ of undefined”
其实产生这个的原因是因为echarts的版本太高了,
可以安装低版本的echarts
npm install echarts@4.8.0 --save或者let echarts = require(‘echarts’)
正确的echarts引入方式:
let echarts = require(‘echarts’)
或
import * as echarts from 'echarts’
在Echarts.vue中
<template>
<div>
<div id="myChart" :style="{width: '300px', height: '300px'}"></div>
</div>
</template>
<script>
let echarts = require(‘echarts’)
export default {
name: 'hello',
data () {
return {
msg: 'Welcome to Your Vue.js App'
}
},
mounted(){
this.drawLine();
},
methods: {
drawLine(){
// 基于准备好的dom,初始化echarts实例
let myChart = echarts.init(document.getElementById('myChart'))
// 绘制图表
myChart.setOption({
title: { text: '在Vue中使用echarts' },
tooltip: {},
xAxis: {
data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
},
yAxis: {},
series: [{
name: '销量',
type: 'bar',
data: [5, 20, 36, 10, 10, 20]
}]
});
//添加点击事件
myChart.on('click', function (params) {
console.log(params,'跳转参数')
});
}
}
}
</script>
