时间:2021-07-01 10:21:17 帮助过:5人阅读

1.安装ngx-echarts

npm install echarts --save
npm install ngx-echarts --save

2.在项目中引入echarts

//angular-cli.json文件

{
  "apps": [{
    "scripts":[
      "../node_modules/echarts/dist/echarts.min.js",
      "../node_modules/echarts/map/js/china.js",
      "../node_modules/echarts/dist/extension/bmap.js"
    ]
  }]
}

3.使用 在你真正需要使用echarts指令的module中import NgxEchartsModule

echarts.module.ts

import { NgModule } from '@angular/core';
import { EchartsComponent } from './echarts/echarts.component';
import { NgxEchartsModule } from 'ngx-echarts';

@NgModule({
 imports: [
  NgxEchartsModule 
 ],
 declarations: [EchartsComponent],
})
export class EchartsModule { }

echarts.component.ts

import { Component, OnInit } from '@angular/core';

@Component({
 selector: 'app-echarts',
 templateUrl: './echarts.component.html',
 styleUrls: ['./echarts.component.scss']
})
export class EchartsComponent implements OnInit {
 showloading:boolean = true;

 constructor() { 
  
  setTimeout(()=> {
   this.showloading = false;
  }, 3000);
 }

 ngOnInit() {
 }
