Vue—echarts的基本使用

<template>
  <div class="datalist">
    <!-- 数据报表容器 -->
    <div id="main" style="width: 750px; height: 400px"></div>
  </div>
</template>

<script>
//引入echarts图表
import * as echarts from "echarts";
import { getReports } from "@/api/api.js";
import _ from "lodash";
export default {
  data() {
    return {

        title: {
          text: "用户来源", //标题
