// 引用Echarts
import * as echarts from 'echarts';
Vue.prototype.$echarts = echarts;

<template>
  <el-row :gutter="12">
    <el-col :span="12">
      <el-card class="box-card">
        <div slot="header" class="clearfix">
          <span>基础仪表盘span>
        div>
        <div id="basic_dashboard" style="width: 100%;height: 400px;">div>
      el-card>
    el-col>
  el-row>
template>

<script>
export default {
  created() {
    this.$nextTick(() => {
      this.basic_dashboard_type()
    })
  },
  data() {
    return {}
  },

  methods: {
    basic_dashboard_type() {
      var chartDom = document.getElementById('basic_dashboard');
      var myChart = this.$echarts.init(chartDom);
      var option = {
        tooltip: {
          formatter: '{a} 
{b} : {c}%'
        },
        series: [
          {
            name: 'Pressure',
            type: 'gauge',
            detail: {
              formatter: '{value}'
            },
            data: [
              {
                value: 50,
                name: 'SCORE'
              }
            ]
          }
        ]
      }
      myChart.setOption(option);
    }
  }
}
