vue.js能用echarts么

vue.js能用echarts，具体操作方法：1、在控制台中输入“npm install echarts --save”命令安装echarts依赖；2、在main.js中进行全局引入，就可以使用echarts创建图表。

本教程操作环境：windows7系统、vue2.9版本，该方法适用于所有品牌电脑。

最近工作中需要用到echarts，由于项目是用的vue-cli开发的。在网上搜到vue中合成了vue-echarts，但是不想使用vue中规定好的数据格式，于是就自己做了一个vue项目引用原生echarts的简单demo，实现过程如下：用了两种实现方式

准备工作

1、安装echarts依赖

控制台输入：npm install echarts --save

2、全局引入

main.js中引入

import echarts from 'echarts'
Vue.prototype.$echarts = echarts

创建图表

第一种创建方式

在一个.vue文件中引入多张图表

创建WelcomePage.vue

<template>
 <div>
 <h1>第一种在vue中使用echart的方式</h1>

 <div class="charts">
  <div id="barGraph" style="height: 350px;"></div>
 </div>

 <div class="charts">
  <div id="pieGraph" style="height: 350px;"></div>
 </div>

 </div>
</template>

<script>
// 引入基本模板,按需加载
 let echarts = require(&#39;echarts/lib/echarts&#39;);
 // 引入柱状图
 require(&#39;echarts/lib/chart/bar&#39;);
 // 引入柱状图
 require(&#39;echarts/lib/chart/pie&#39;);
 require(&#39;echarts/lib/component/tooltip&#39;);
 require(&#39;echarts/lib/component/title&#39;);


export default {
 name: "WelcomePage",
 data () {
 return { }
 },
 mounted(){
 this.drawBar();
 this.drawPie();
 },
 methods:{
 drawBar(){
  // 基于dom，初始化echarts实例
  let barGraph = echarts.init(document.getElementById(&#39;barGraph&#39;));
  // 绘制图表
  barGraph.setOption({
  title: {
   text: &#39;全年产量趋势图&#39;,
   left: &#39;center&#39;
  },
  tooltip: {
   trigger: &#39;item&#39;,

   },
  ]
  })
 },
 drawPie(){
  let pieGraph = echarts.init(document.getElementById(&#39;pieGraph&#39;));
  pieGraph.setOption({

    }
   }
   }
  ]
  })
 }
 }
}
</script>

实现效果如下图：

第二种实现方式（以组件的形式）

创建父组件 father.vue

<div>
 <h1>{{ msg }}</h1>
 <p>第二种方式：通过组件的方式进行页面渲染</p>
 <div class="container" >
  <bar-graph></bar-graph>
 </div>

 <div class="container">
  <pie-graph></pie-graph>
 </div>

 </div>

<script>
// 引入两个子组件
 import BarGraph from "./bargraph";
 import PieGraph from "./piegraph";
 export default {
 name: "father",
 components:{
  BarGraph,
  PieGraph,
 },
 data(){
  return{
  msg: &#39;我是爸爸，想看我的儿子，眼睛请往下移&#39;,
  }
 }
 }
</script>

创建子组件barGraph.vue

 <div>
 <p>{{ msg }}</p>
 <div class="charts">
  <div :id="id" style="min-height: 350px;"></div>
 </div>
 </div>

<script>
 let echarts = require(&#39;echarts/lib/echarts&#39;);

    }
    ]
   }
   )
  }
  }
 }
</script>

创建pieGraph.vue

<template>
 <div>
  <p>{{ msg }}</p>

  <div class="charts">
  <div :id="id" style="min-height: 350px;"></div>
  </div>
 </div>
</template>

<script>
 import echarts from &#39;echarts&#39;

 export default {
  name: "piegraph",
  props:{
  id: {
   type: String,
   default: &#39;pieChart&#39;
  }
  },
  data(){
   return{
   msg: &#39;我是第二个子组件--pie&#39;,
   pieChart: null
   }
  },
  mounted(){
   this.drawPie();
  },
  methods: {
  drawPie () {
   this.pieChart = echarts.init(document.getElementById(this.id));
   this.pieChart.setOption(
   {
    title : {
    text: &#39;某站点用户访问来源&#39;,
    subtext: &#39;纯属虚构&#39;,
    x:&#39;center&#39;
    },
    tooltip : {
    trigger: &#39;item&#39;,
    formatter: "{a} <br/>{b} : {c} ({d}%)"
    },
    legend: {
    orient: &#39;vertical&#39;,
    left: &#39;left&#39;,
    data: [&#39;直接访问&#39;,&#39;邮件营销&#39;,&#39;联盟广告&#39;,&#39;视频广告&#39;,&#39;搜索引擎&#39;]
    },
    series : [
    {
     name: &#39;访问来源&#39;,
     type: &#39;pie&#39;,
     radius : &#39;55%&#39;,
     center: [&#39;50%&#39;, &#39;60%&#39;],
     data:[
     {value:335, name:&#39;直接访问&#39;},
     {value:310, name:&#39;邮件营销&#39;},
     {value:234, name:&#39;联盟广告&#39;},
     {value:135, name:&#39;视频广告&#39;},
     {value:1548, name:&#39;搜索引擎&#39;}
     ],
     itemStyle: {
     emphasis: {
      shadowBlur: 10,
      shadowOffsetX: 0,
      shadowColor: &#39;rgba(0, 0, 0, 0.5)&#39;
     }
     }
    }
    ]
   }
   )
  }
  }
 }
</script>

效果实现如下：

路由文件如下：

import WelcomePage from '@/components/WelcomePage'
import Father from '@/components/father'

import BarGraph from '@/components/bargraph'
import PieGraph from '@/components/piegraph'

export default new Router({
 routes: [
 {
  path: '/',
  name: 'WelcomePage',
  component: WelcomePage
 },
 {
  path: '/father',
  name: 'father',
  component: Father,
  children:[
  {
   path: '/bargraph',
   name: 'bargraph',
   component: BarGraph
  },
  {
   path: '/piegraph',
   name: 'piegraph',
   component: PieGraph
  }
  ]
 },
 ]
})
