angular11 引入echarts

1、项目下载echarts的npm包

项目根目录执行命令：

npm install echarts --save

下载成功后项目的package.json文件中的‘dependencies’对象下会自动添加‘echarts’，并标注你下载的版本

"dependencies": {
    "@angular/animations": "~11.2.1",
    "@angular/common": "~11.2.1",
    "@angular/compiler": "~11.2.1",
    "@angular/core": "~11.2.1",
    "@angular/forms": "~11.2.1",
    "@angular/platform-browser": "~11.2.1",
    "@angular/platform-browser-dynamic": "~11.2.1",
    "@angular/router": "~11.2.1",
    "echarts": "^5.3.2",
    "ng-zorro-antd": "^11.4.2",
    "rxjs": "~6.6.0",
    "tslib": "^2.0.0",
    "zone.js": "~0.11.3"
  },

 2、下载成功后，在你需要绘制图表的组件的ts文件中导入echarts

import * as echarts from 'echarts';

具体使用demo如下：

ts：

import {AfterViewInit, Component, OnInit, ViewChild} from '@angular/core';
import * as echarts from 'echarts';

@Component({
  selector: 'app-echart',
  templateUrl: './echart.component.html',
  styleUrls: ['./echart.component.less']
})
export class EchartComponent implements OnInit, AfterViewInit {
  chart: any;
  @ViewChild('chartTpl') chartTpl;

  constructor() {
  }

  ngOnInit(): void {
  }

  ngAfterViewInit(): void {
　　// 需要等页面加载完成后才能获取页面元素
    this.initChart();
  }

  /**
   * 初始化图表
   */
  initChart(): void {
    this.chart = echarts.init(this.chartTpl.nativeElement);
    /**
     * 绑定resize
     */
    window.addEventListener('resize', () => {
      this.chart.resize();
    });
    this.chart.setOption({
      xAxis: {
        type: 'category',
        data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
      },
      yAxis: {
        type: 'value'
      },
      series: [
        {
          data: [120, 200, 150, 80, 70, 110, 130],
          type: 'bar',
          showBackground: true,
          backgroundStyle: {
            color: 'rgba(180, 180, 180, 0.2)'
          }
        }
      ]
    });
  }
}

html：

<div #chartTpl style=" 600px;height: 300px"></div>
