前言

本文将介绍如何在vue project中引入echarts，在引入echarts之前首先需要添加echarts的依赖包。

• vue2.0框架添加方法。

npm install echarts

• vue3.0框架添加方法。

npm add echarts

全局引入

在全局引入，需要在main.js文件中，引入echarts。

1. 全部引入

import echarts from 'echarts

Vue.prototype.$echarts = echarts

2. 按需引入

// echarts 按需引入
let echarts2 = require('echarts/lib/echarts')

// 引入折线图等组件
require('echarts/lib/chart/line')
require('echarts/lib/chart/bar')
require('echarts/lib/chart/radar')

// 引入提示框和title组件，图例
require('echarts/lib/component/tooltip')
require('echarts/lib/component/title')
require('echarts/lib/component/legend')

Vue.prototype.$echarts2 = echarts2

局部引入

局部引入echarts就是在单个vue文件中，引入echarts进行使用。

1. 全部引入

import echarts from "echarts";

2. 按需引入

// echarts 按需引入
let echarts2 = require("echarts/lib/echarts");

// 引入折线图等组件
require("echarts/lib/chart/line");
require("echarts/lib/chart/bar");
require("echarts/lib/chart/radar");

// 引入提示框和title组件，图例
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
require("echarts/lib/component/legend");

代码示例

<template>
<div class="container">
<div id="main1" class="box"></div>
<div id="main2" class="box"></div>
<div id="main3" class="box"></div>
<div id="main4" class="box"></div>
</div>
</template>
<script>
import echarts from "echarts";
// echarts 按需引入
let echarts2 = require("echarts/lib/echarts");
// 引入折线图等组件
require("echarts/lib/chart/line");
require("echarts/lib/chart/bar");
require("echarts/lib/chart/radar");
// 引入提示框和title组件，图例
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
require("echarts/lib/component/legend");
export default {
name: "",
components: {},
mounted() {
this.initChart();
},
data() {
return {};
},
methods: {
initChart() {
let myChart1 = this.$echarts.init(document.getElementById('main1'));
let myChart2 = this.$echarts2.init(document.getElementById('main2'));
let myChart3 = echarts.init(document.getElementById('main3'));
let myChart4 = echarts2.init(document.getElementById('main4'));
// 绘制图表
myChart1.setOption(this.setOption('全局全部引入'));
myChart2.setOption(this.setOption('全局按需引入'));
myChart3.setOption(this.setOption('局部全部引入'));
myChart4.setOption(this.setOption('局部按需引入'));
},
setOption(title) {
let option = {
title: { text: title },
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]
}
]
};
return option;
}
}
};
</script>
<style scoped>
.container {
position: relative;
margin: 0;
padding: 0;
display: flex;
justify-content: space-around;
}
.box {
width: 300px;
height: 300px;
border: 2px solid #000;
}
</style>
