我正在尝试使用 NG2-Charts 的基本图表（http://valor-software.com/ng2-charts/）
我复制粘贴了 HTML 部分
<div>
<div style="display: block">
<canvas baseChart
[datasets]="barChartData"
[labels]="barChartLabels"
[options]="barChartOptions"
[legend]="barChartLegend"
[chartType]="barChartType"
(chartHover)="chartHovered($event)"
(chartClick)="chartClicked($event)"></canvas>
</div>
<button (click)="randomize()">Update</button>
</div>
和 TypeScript 部分
import { Component, AfterViewInit } from '@angular/core';
import { Test2Service } from './test2.service';
@Component({
selector: 'test',
templateUrl: './test2.html',
styleUrls: ['./test2.css']
})
export class Test2Component implements AfterViewInit {
private name: string = 'You';
constructor(private helloWorldService: Test2Service) {
}
ngAfterViewInit(): void {
this.name = 'Me';
}
private getAnswer() {
return this.helloWorldService.giveMeTheAnswer();
}
public barChartOptions: any = {
scaleShowVerticalLines: false,
responsive: true
};
public barChartLabels: string[] = ['2006', '2007', '2008', '2009', '2010', '2011', '2012'];
public barChartType: string = 'bar';
public barChartLegend: boolean = true;
public 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
public chartClicked(e: any): void {
console.log(e);
}
public chartHovered(e: any): void {
console.log(e);
}
public randomize(): void {
// Only Change 3 values
let data = [
Math.round(Math.random() * 100),
59,
80,
(Math.random() * 100),
56,
(Math.random() * 100),
40];
let clone = JSON.parse(JSON.stringify(this.barChartData));
clone[0].data = data;
this.barChartData = clone;
}
}
我跑npm install ng2-charts --save和 npm install chart.js --save。然后我导入<script src="node_modules/chart.js/src/chart.js"></script>我的index.html.
在此之后，我将它导入到我的 AppModule 中：
import { ChartsModule } from 'ng2-charts';
...
...
...
imports: [
...
...
ChartsModule,
...
],
...
然后我添加'ng2-charts':'npm:ng2-charts/bundles/ng2-charts.umd.js'到我的systemjs.config.js
现在我也尝试执行我的 Angular 2 应用程序，但出现以下错误：
Uncaught ReferenceError: require is not defined
at chart.js:4
