*模板项目源码在文章最后获取哦~

一、先npm安装echarts

npm install echarts --save

二、引入使用

1.全局引入main.js中配置（不推荐使用）

import echarts from 'echarts' //引入echarts
Vue.prototype.$echarts = echarts //挂载在原型，组件内使用直接this.$echarts调用

2.组件内按需引入（推荐使用）
这种方式很简单，在需要引入图表的组件引入,例如如下引入柱状图。具体使用干什么样子的组件需要引入什么可以参考引入示例

//引入基本模板
let echarts = require("echarts/lib/echarts");
// 引入柱状图组件
require("echarts/lib/chart/bar");

三、项目中应用

1.直接上效果图果断干脆

2.目录结构
每一块图表都是一个组件的形式呈现，方便对echarts的修改

first.vue组件代码示例如下，其他组件可以比葫芦画瓢

<template>
  <div class="visual-chart1" id="myChart1"></div>
</template>

<script>

    this.chartsView();
