这个想法是将chart.js与Angular 4和ng2-charts一起使用。我正在使用此处的示例，但无法使其正常工作。

我收到以下错误消息：

无法绑定到“数据”，因为它不是“画布”的已知属性

我已经将它导入 app.module.ts，因为大多数帖子都建议出现此错误。有什么我想念的吗？

...组件.html：

<div style="display: block">
    <canvas baseChart
        [data]="data"
        [labels]="labels"
        [chartType]="type">
    </canvas>
</div>

...组件.ts

...
labels:string[] = ['Download Sales', 'In-Store Sales', 'Mail-Order Sales'];
data:number[] = [350, 450, 100];
type:string = 'doughnut';
...

索引.html：

<script src="lib/chart.js/dist/chart.js"></script>

app.module.ts：

import { ChartsModule } from 'ng2-charts/ng2-charts';
imports: [
    ...
    ChartsModule,
    ...
],

系统.js

map: {
    ...
    'ng2-charts': 'npm:ng2-charts/bundles'
},
packages: {
    ...
    'ng2-charts': {
         defaultExtension: 'js'
    }
}

包.json：

  "@angular/animations": "^4.3.0",

经过几个小时的尝试和错误，我让它工作了。我更改了以下内容：

app.module.ts：

import { ChartsModule } from 'ng2-charts';

系统.js：

map: {
    ...
    'ng2-charts': 'npm:ng2-charts/bundles'
},
packages: {
    ...
    'ng2-charts': {
         main: 'ng2-charts.umd.min.js',
         defaultExtension: 'js'
    }
}
