Vue项目中引入 ECharts

npm install echarts --save

import * as echarts from "echarts";

<template>
  <div
    class="echart"
    id="mychart"
    :style="{ float: 'left', width: '100%', height: '400px' }"
  ></div>
</template>

<script>
import * as echarts from "echarts";

export default {
  data() {
    return {
      name: "张雪",
      xData: ["2020-02", "2020-03", "2020-04", "2020-05"], //横坐标数据
      yData: [30, 132, 80, 134] //纵坐标数据，与横坐标对应
    };
  },
  mounted() {
    this.initEcharts();
  },
  methods: {
    initEcharts() {
      const 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", //类型为柱状图
            data: [5, 20, 36, 10, 10, 20]
          }
        ]
      };
      const myChart = echarts.init(document.getElementById("mychart"));// 图标初始化
      myChart.setOption(option);// 渲染页面
      //随着屏幕大小调节图表
      window.addEventListener("resize", () => {
        myChart.resize();
      });
    }
  }
};
</script>

// 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 } 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,
  DatasetComponentOption,
  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([
  TitleComponent,
  TooltipComponent,
  GridComponent,
  DatasetComponent,
  TransformComponent,
  BarChart,
  LabelLayout,
  UniversalTransition,
  CanvasRenderer
]);

// 接下来的使用就跟之前一样，初始化图表，设置配置项
var myChart = echarts.init(document.getElementById('main'));
myChart.setOption({
  // ...
});
