Der Inhalt dieses Artikels befasst sich mit der Methode (Codebeispiel) zur Einführung von Echarts in Angular4. Ich hoffe, dass er für Freunde hilfreich ist.
1. Installieren Sie ngx-echarts
npm install echarts --save
npm install ngx-echarts --save
2 Projekt 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. Verwenden Sie 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() {
}

}in dem Modul, das Sie wirklich verwenden müssen die Echarts-Anweisung. echarts.component.html
<div echarts [options] = "chartOption" [loading]="showloading" class="demo-chart"></div> <div echarts [options] = "Baroptions" [loading]="showloading" class="demo-chart"></div> <div echarts [options] = "linkoption" [loading]="showloading" class="demo-chart"></div> <div echarts [options] = "mapoption" [loading]="showloading" class="demo-chart"></div>
Das obige ist der detaillierte Inhalt vonSo führen Sie Echarts in Angular4 ein (Codebeispiel). Für weitere Informationen folgen Sie bitte anderen verwandten Artikeln auf der PHP chinesischen Website!
