ECharts官网地址

全局引入
main.js

import * as echarts from "echarts"
Vue.prototype.$echarts = echarts

按需引入
main.js

// 引入 echarts 核心模块，核心模块提供了 echarts 使用必须要的接口。
import * as echarts from 'echarts/core';

// 引入柱状图图表，图表后缀都为 Chart
import { BarChart, LineChart } from 'echarts/charts';

// 引入提示框，标题，直角坐标系，数据集，内置数据转换器组件，组件后缀都为 Component
import {
  TitleComponent,
  TooltipComponent,
  GridComponent,
  DatasetComponent,
  TransformComponent
} from 'echarts/components';

// 标签自动布局，全局过渡动画等特性
import { LabelLayout, UniversalTransition } from 'echarts/features';
// 引入 Canvas 渲染器，注意引入 CanvasRenderer 或者 SVGRenderer 是必须的一步
import { CanvasRenderer } from 'echarts/renderers';

// 注册必须的组件
echarts.use([
  BarChart,
  LineChart,
  TitleComponent,
  TooltipComponent,
  GridComponent,
  DatasetComponent,
  TransformComponent,
  LabelLayout,
  UniversalTransition,
  CanvasRenderer,
]);

Vue.prototype.$echarts = echarts

组件中使用

<template>
  <div>
    <div id="test"></div>
  </div>
</template>

<script>
export default {
  data() {
    return {};
  },
  mounted() {
    this.getECharts();
  },
  methods: {
    getECharts() {
      // 基于准备好的dom，初始化echarts实例
      var myChart = this.$echarts.init(document.getElementById("test"), null, {
        // width: 100,
        height: 200,
      });
      // 绘制图表
      myChart.setOption({
        title: {
          text: "ECharts 入门示例",
        },
        tooltip: {},
        xAxis: {
          data: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"],
        },
        yAxis: {},
        series: [
          {
            name: "销量",
            type: "line",
            data: [5, 20, 36, 10, 10, 20],
          },
        ],
      });
      //防抖
      let timer;
      window.onresize = function () {
        if (timer) {
          clearTimeout(timer);
        }
        timer = setTimeout(() => {
          myChart.resize();
        }, 500);
      };
    },
  },
};
