Angular2和NG2-Charts不显示任何图表



我需要在我的项目中实现一些图表,该图表(版本2.4.8),我使用ng2-charts(版本1.5.0),以及使用Chart.js的版本。是2.5.0。首先,我从NG2-Charts网站复制了一个示例代码,但没有错误,但没有图表...与Angular2?

的NG2-Charts有些破坏了变化。

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);
    }
}

查看:homeview.html

<div style="display: block">
    <canvas baseChart
        [data]="doughnutChartData"
        [labels]="doughnutChartLabels"
        [chartType]="doughnutChartType"
        (chartHover)="chartHovered($event)" (chartClick)="chartClicked($event)">                                                                                                 
    </canvas> 
</div>

systemjs: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 {
}

index.html:

<script src="node_modules/chart.js/dist/Chart.bundle.js"></script>

我尝试使用src/chart.js之类的网站示例,但这会出错(不定定义)和dist/chart.js。

搜索4个小时后,我转向您...一些想法?谢谢

我找到了答案,这是因为我使用了外部lib(mdbootstrap)break break break break break break break with一些依赖关系...我猜

谢谢
