我正在尝试使用 NG2-Charts 的基本示例(http://valor-software.com/ng2-charts/)
我复制粘贴了 HTML 部分
<div style="display: block">
<canvas baseChart
[datasets]="barChartData"
[labels]="barChartLabels"
[options]="barChartOptions"
[legend]="barChartLegend"
[chartType]="barChartType"
(chartHover)="chartHovered($event)"
(chartClick)="chartClicked($event)"></canvas>
和 TypeScript 部分
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;
/**
* (My guess), for Angular to recognize the change in the dataset
* it has to change the dataset variable directly,
* so one way around it, is to clone the data, change it and then
* assign it;
*/
}
我运行 npm install ng2-charts --save,npm install chart.js --save
我还在 app.module.ts 中导入 ChartsModule
import { ChartsModule } from 'ng2-charts/ng2-charts';
@NgModule({
imports: [ChartsModule]
})
导入 ChartsModule 后,我收到ng2-charts\ng2-charts.js 不导出 ChartsModule 的错误。 点击查看错误图片
有谁知道如何解决这个问题?谢谢
