Javascript Question

NG2-Charts Can't bind to 'datasets' since it isn't a known property of 'canvas'

I am trying to use the basic example of NG2-Charts (http://valor-software.com/ng2-charts/)

I copy pasted the HTML part

<div style="display: block">
<canvas baseChart
[datasets]="barChartData"
[labels]="barChartLabels"
[options]="barChartOptions"
[legend]="barChartLegend"
[chartType]="barChartType"
(chartHover)="chartHovered($event)"
(chartClick)="chartClicked($event)"></canvas>
</div>


and the TypeScript part

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);
}


I run
npm install ng2-charts --save
,
npm install chart.js --save
and
typings install dt~chart.js --save --global


I also imported chart.js in my vendor.ts file

import 'chart.js';


My dependencies:

{
"@angular/common": "^2.0.0",
"@angular/compiler": "2.0.0",
"@angular/core": "2.0.0",
"@angular/forms": "2.0.0",

Here is the Error

The NG2-Charts website says I need to include this in the HTML

<script src="node_modules/chart.js/src/chart.js"></script>


But I think thats not correct because how would that statement work in a productive minified / built app? I also thought my webpack import statement would already take care of that?
I googled around but sadly only found stuff for some Angular 2 Beta version on NG2 Charts.

Does anyone has an idea on how to fix that?

Thanks and Cheers,

Answer

Try importing ChartsModule in your app.module.ts like this-

import { ChartsModule } from 'ng2-charts/ng2-charts';

imports: [
   .....
   ChartsModule
   .....
]
