A preliminary study on the use of Echarts in the Vue project

1. First build the basic framework of the Report.vue component

<template>
  <div>
    <!-- 面包屑导航 -->
    <el-breadcrumb separator-class="el-icon-arrow-right">
      <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
      <el-breadcrumb-item>数据统计</el-breadcrumb-item>
      <el-breadcrumb-item>数据报表</el-breadcrumb-item>
    </el-breadcrumb>
    <!-- 卡片视图区 -->
    <el-card>
      <!-- 为 ECharts 准备一个具备大小（宽高）的 DOM -->
      <div id="main" style="width: 600px; height: 400px"></div>
    </el-card>
  </div>
</template>
<script>
export default {
    
    
  data() {
    
    
    return {
    
    }
  },
  created() {
    
    },
  methods: {
    
    }
}
</script>

<style lang="less" scoped>
</style>

2. Import echarts:

import echarts from 'echarts'

3. Execute after the DOM of the page is loaded:

  mounted() {
    
    
    // 基于准备好的dom，初始化echarts实例
    var myChart = echarts.init(document.getElementById('main'))
    // 指定图表的配置项和数据
    var option = {
    
    
      title: {
    
    
        text: 'ECharts 入门示例'
      },
      tooltip: {
    
    },
      legend: {
    
    
        data: ['销量']
      },
      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]
        }
      ]
    }
    // 使用刚指定的配置项和数据显示图表。
    myChart.setOption(option)

Save and run. If an error like echarts Cannot read property 'init' of undefinedthis type is reported, reinstall the latest version of echarts and restart the entire project.
