Ответ 1
Попробуйте импортировать ChartsModule в свой app.module.ts, как это -
import { ChartsModule } from 'ng2-charts/ng2-charts';
imports: [
.....
ChartsModule
.....
]
Я пытаюсь использовать базовый пример NG2-Charts (http://valor-software.com/ng2-charts/)
Я скопирую в HTML-часть
<div style="display: block">
<canvas baseChart
[datasets]="barChartData"
[labels]="barChartLabels"
[options]="barChartOptions"
[legend]="barChartLegend"
[chartType]="barChartType"
(chartHover)="chartHovered($event)"
(chartClick)="chartClicked($event)"></canvas>
</div>
и TypeScript часть
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);
}
Я запускаю npm install ng2-charts --save
, npm install chart.js --save
и typings install dt~chart.js --save --global
Я также импортировал файл chart.js в файле vendor.ts
import 'chart.js';
Мои зависимости:

На сайте NG2-Charts говорится, что мне нужно включить это в HTML
<script src="node_modules/chart.js/src/chart.js"></script>
Но я думаю, что это неверно, потому что как бы это выражение работало в продуктивном минифинированном/построенном приложении? Я также думал, что моя заявка на импорт webpack уже позаботится об этом? Я googled вокруг, но, к сожалению, только нашел материал для некоторой версии Angular 2 Beta на диаграммах NG2.
Есть ли у кого-нибудь идея, как это исправить?
Спасибо и приветствую, Рафаэль Хиппе
Попробуйте импортировать ChartsModule в свой app.module.ts, как это -
import { ChartsModule } from 'ng2-charts/ng2-charts';
imports: [
.....
ChartsModule
.....
]
В моем случае мне пришлось изменить способ импорта и небольшое изменение в моем теге html файла:
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 => `${label.toLocaleString()}`
}
}]
}
};
public barChartLabels:string[] = ['2014', '2015', '2016'];
public barChartType:string = 'bar';
public barChartLegend:boolean = true;
public barChartData:any[] = [
{data: [32131, 3432, 543], label:'Test 1'},
{data: [54353, 432, 768], label:'Test 2'}
];
// events
public chartClicked(e:any):void {
console.log(e);
}
public chartHovered(e:any):void {
console.log(e);
}
}
Вот еще одно изменение:
notice → base-chart class= "chart"...
график-balance.template
<base-chart class="chart"
[datasets]="barChartData"
[labels]="barChartLabels"
[options]="barChartOptions"
[legend]="barChartLegend"
[chartType]="barChartType"
(chartHover)="chartHovered($event)"
(chartClick)="chartClicked($event)"></base-chart>
