vue文件如何使用echarts.js？（两种方法介绍）

本篇文章给大家带来的内容是关于vue文件如何使用echarts.js？（两种方法介绍），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。
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

1 2	`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('echarts/lib/echarts');
  // 引入柱状图
  require('echarts/lib/chart/bar');
  // 引入柱状图
  require('echarts/lib/chart/pie');
  require('echarts/lib/component/tooltip');
  require('echarts/lib/component/title');


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('barGraph'));
      // 绘制图表
      barGraph.setOption({
        title: {
          text: '全年产量趋势图',
          left: 'center'
        },
        tooltip: {
          trigger: 'item',
          formatter: '{a} <br/>{b} : {c}'
        },
        legend: {
          left: 'center',
          data: ['本年', '上年'],
          bottom:0
        },
        xAxis: {
          type: 'category',
          name: 'x',
          splitLine: {show: false},
          data: ['一月', '二月', '三月', '四月', '五月', '六月', '七月', '八月', '九月', '十月', '十一月', '十二月']
        },
        grid: {
          left: '1%',
          right: '2%',
          bottom: '8%',
          containLabel: true
        },
        yAxis: {
          type: 'category',
          name: 'y',
          splitLine: {show: true},
          data:['10%','20%','30%','40%','50%','60%','70%','80%','90%','100%']
        },
        series: [
          {
            name: '本年',
            type: 'line',
            data: [0.8, 0.98, 0.96, 0.27, 0.81, 0.47, 0.74, 0.23, .69, 0.25, 0.36, 0.56]
          },
          {
            name: '上年',
            type: 'line',
            data: [1, 0.2, 0.4, 0.8, 0.16, 0.32, 0.64, 1.28, 5.6, 0.25, 0.63, 0.65, 0.12]
          },
        ]
      })
    },
    drawPie(){
      let pieGraph = echarts.init(document.getElementById('pieGraph'));
      pieGraph.setOption({
        title : {
          text: '某站点用户访问来源',
          subtext: '纯属虚构',
          x:'center'
        },
        tooltip : {
          trigger: 'item',
          formatter: "{a} <br/>{b} : {c} ({d}%)"
        },
        legend: {
          orient: 'vertical',
          left: 'left',
          data: ['直接访问','邮件营销','联盟广告','视频广告','搜索引擎']
        },
        series : [
          {
            name: '访问来源',
            type: 'pie',
            radius : '55%',
            center: ['50%', '60%'],
            data:[
              {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'}
            ],
            itemStyle: {
              emphasis: {
                shadowBlur: 10,
                shadowOffsetX: 0,
                shadowColor: 'rgba(0, 0, 0, 0.5)'
              }
            }
          }
        ]
      })
    }
  }
}
</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: '我是爸爸，想看我的儿子，眼睛请往下移',
      }
    }
  }
</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>

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 'echarts'

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