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

J'essaie d'utiliser ng2-charts et je rencontre une erreur qui dit que les éléments que j'utilise sont incorrects.
J'ai essayé quelques réponses sur ce site, mais pas de chance:

NG2-Charts ne peut pas se lier à des 'ensembles de données' car ce n'est pas une propriété connue de 'canvas'

ng2-charts - Impossible de se lier aux 'ensembles de données' car ce n'est pas une propriété connue de 'base-chart'

Voici mon code:

import { Component } from "@angular/core";

@Component({
    moduleId: module.id,
    templateUrl: "four-item-horse-shoe-graph.component.html",
    styleUrls: ["four-item-horse-shoe-graph.component.css"],
    selector: "four-item-horse-shoe"
})

export class FourItemHorseShoeGraphComponent {
    // 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);
    }
}

Et le HTML:

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

systemjs.config.js:

            'chart': 'npm:chart.js/src/chart.js',
        "ng2-charts": "node_modules/ng2-charts"
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
        app: {
            main: './main.js',
            defaultExtension: 'js'
        },
        rxjs: {
            defaultExtension: 'js'
        },
        "ng2-charts": { main: "ng2-charts.js", defaultExtension: "js" }

app.module.ts

J'avais besoin d'importer le ChartModule dans le fichier module.ts du composant dans lequel je voulais utiliser le graphique. Au départ, je l'avais seulement importé dans app.module.ts.

ArtisanSamosa

Essayez d'utiliser la syntaxe d'attribut pour la liaison:

Au lieu de:

[data]="doughnutChartData"

Essayer:

attr.data="{{doughnutChartData}}"

Je ne sais pas si cela fonctionnera dans votre cas, mais cela a à voir avec ce qu'est une propriété DOM par rapport à un attribut, et comment Angular gère la liaison pour les deux.

chrispy

Dans le fichier app.module.ts, dans le décorateur NgModule, il y a un tableau appelé imports, mentionnez ChartsModule dans le tableau des importations comme ceci

importe: [BrowserModule, RouterModule.forRoot (appRoutes), ChartsModule],

Ça m'a aidé. Cela peut aussi vous être utile

Pour Angular 7 ou version supérieure, utilisez

npm install [email protected]

--save npm install chart.js --save
