我需要在我的项目中实现一些图表,内置 Angular2(版本 2.4.8),我使用 ng2-charts(版本 1.5.0),chart.js 使用的版本是 2.5.0。首先,我从 ng2-charts 网站复制了一个示例代码,我没有错误,但没有图表... ng2-charts 与 Angular2 的一些重大变化?
我使用图表的组件:HomeComponent.ts
import { Component, VERSION } from '@angular/core';
@Component({
selector: 'pulpe-home-cmp',
templateUrl: './app/components/Home/HomeView.html'
})
export class HomeComponent {
constructor(){
console.log(VERSION.full)
}
// Doughnut
public doughnutChartLabels:string[] = ['Download Sales', 'In-Store Sales', 'Mail-Order Sales'];
public doughnutChartData:number[] = [350, 450, 100];
public doughnutChartType:string = 'doughnut';
// events
public chartClicked(e:any):void {
console.log(e);
}
public chartHovered(e:any):void {
console.log(e);
}
}
视图:HomeView.html
<div style="display: block">
<canvas baseChart
[data]="doughnutChartData"
[labels]="doughnutChartLabels"
[chartType]="doughnutChartType"
(chartHover)="chartHovered($event)" (chartClick)="chartClicked($event)">
</canvas>
</div>
系统js:systemjs.config.js
map: { ...
'ng2-charts': 'node_modules/ng2-charts'
},
package : {
'ng2-charts': { main: 'ng2-charts.js', defaultExtension: 'js' }
}
我的应用模块:app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { PulpeAppComponent } from './app.component';
import { HomeComponent } from './components/Home/HomeComponent';
import { MenuBarComponent } from './components/MenuBar/MenuBarComponent';
import { SigninComponent } from './components/Signin/SigninComponent';
import { RouterModule } from '@angular/router'
import { ROUTES } from './app.routes'; // ROUTING HERE!
import { APP_BASE_HREF } from '@angular/common';
import { ChartsModule } from 'ng2-charts';
@NgModule({
imports: [BrowserModule, RouterModule.forRoot(ROUTES), ChartsModule],
declarations: [
PulpeAppComponent,
MenuBarComponent,
HomeComponent,
SigninComponent
],
bootstrap: [PulpeAppComponent],
providers:[
{provide: APP_BASE_HREF, useValue : '/' }
]
})
export class PulpeModule {
}
索引.html:
<script src="node_modules/chart.js/dist/Chart.bundle.js"></script>
我已经尝试过使用 src/chart.js ,例如网站示例,但会出错(未定义要求)和 dist/Chart.js 但相同,也就是没有显示...
经过 4 小时的搜索后,我求助于您……一些想法?谢谢
