NG2-Charts Impossible de se lier aux 'ensembles de données' car ce n'est pas une propriété connue de 'canvas'

J'essaie d'utiliser l'exemple de base de NG2-Charts ( http://valor-software.com/ng2-charts/ )

Je copie la partie HTML collée

  <div style="display: block">
    <canvas baseChart
        [datasets]="barChartData"
        [labels]="barChartLabels"
        [options]="barChartOptions"
        [legend]="barChartLegend"
        [chartType]="barChartType"
        (chartHover)="chartHovered($event)"
        (chartClick)="chartClicked($event)"></canvas>
  </div>

et la partie TypeScript

  private barChartOptions: any = {
    scaleShowVerticalLines: false,
    responsive: true
  };
  private barChartLabels: string[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
  private barChartType: string = 'bar';
  private barChartLegend: boolean = true;

  private barChartData: any[] = [
    { data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A' },
    { data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B' }
  ];

  // events
  private chartClicked(e: any): void {
      console.log(e);
  }

  private chartHovered(e: any): void {
      console.log(e);
  }

Je lance npm install ng2-charts --save, npm install chart.js --save et typings install dt~chart.js --save --global

J'ai aussi importé chart.js dans mon fichier vendor.ts

import 'chart.js';

Le site Web NG2-Charts indique que je dois l'inclure dans le code HTML.

<script src="node_modules/chart.js/src/chart.js"></script>

Mais je pense que ce n'est pas correct car comment cette déclaration fonctionnerait-elle dans une application productive/construite/minifiée? Je pensais aussi que ma déclaration d'importation Webpack prendrait déjà soin de cela? J'ai cherché sur Google mais n’ai malheureusement trouvé que des éléments d’une version bêta de Angular 2 sur NG2 Charts. 

Quelqu'un at-il une idée sur la façon de résoudre ce problème? 

Merci et à la vôtre, Raphael Hippe

Essayez d'importer ChartsModule dans vos app.module.ts comme ceci-

import { ChartsModule } from 'ng2-charts/ng2-charts';

imports: [
   .....
   ChartsModule
   .....
]

J'ai eu le même problème. J'ai trouvé sur github que vous devez simplement insérer le ChartsModule dans le sous-module. D'abord, vous ajoutez app.module.ts et le, dans mon cas, reports.module.ts.

Dans mon cas, je devais changer la façon dont j'importais et modifier un peu mon tag de fichier html:

chart.component.ts 

import {Component} from '@angular/core';
import {CHART_DIRECTIVES} from 'ng2-charts/ng2-charts';

@Component({
    selector: 'chart-balance',
    template: require('./templates/chart-balance.template'),
    styles: [`.chart {display: block; width: 100%;}`],
    directives: [CHART_DIRECTIVES]
})

export class ChartBalanceComponent {
    public barChartOptions:any = {
        scaleShowVerticalLines: false,
        responsive: true,
        scales: {
            yAxes: [{
                ticks: {
                    beginAtZero: true,
                    callback: label => `${label.toLocaleString()}`
                }
            }]
        }
    };
    public barChartLabels:string[] = ['2014', '2015', '2016'];
    public barChartType:string = 'bar';
    public barChartLegend:boolean = true;

    public barChartData:any[] = [
        {data: [32131, 3432, 543], label:'Test 1'},
        {data: [54353, 432, 768], label:'Test 2'}
    ];

    // events
    public chartClicked(e:any):void {
        console.log(e);
    }

    public chartHovered(e:any):void {
        console.log(e);
    }

}

Voici un autre changement que j'ai fait:

remarque -> base-chart class = "chart" ...

chart-balance.template 

<base-chart class="chart"
        [datasets]="barChartData"
        [labels]="barChartLabels"
        [options]="barChartOptions"
        [legend]="barChartLegend"
        [chartType]="barChartType"
        (chartHover)="chartHovered($event)"
        (chartClick)="chartClicked($event)"></base-chart>

ng2-charts 

export * from './components/charts/charts';
declare var _default: {
    directives: any[][];
};
export default _default;

graphiques 

import { OnDestroy, OnInit, OnChanges, EventEmitter, ElementRef } from '@angular/core';
export declare class BaseChartComponent implements OnDestroy, OnChanges, OnInit {
    static defaultColors: Array<number[]>;
    data: number[] | Array<number[]>;
    datasets: any[];
    labels: Array<any>;
    options: any;

    constructor(element: ElementRef);

    getChartBuilder(ctx: any): any;
    private refresh();
}
