这篇文章主要介绍了angular4中引入echarts的方法示例，长沙网络推广觉得挺不错的，现在分享给大家，也给大家做个参考。一起跟随长沙网络推广过来看看吧
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() {
}
