title: Ng2-Charts Linechart only showing first 2 two values
body: <p>I'm starting new Angular application which I initialised with Angular-CLI (beta 22.1). But when I add test-data (5 values) to my chart it seems to scale wrong and only shows the first two values and streched them over the whole length of the graph (see picture).</p>

  <p>The project is otherwise blank and does not contain any CSS whatsoever.</p>
  
  <p>My <code>app.component.html</code>:</p>
  
  <pre><code>&lt;div&gt;
      &lt;canvas baseChart [datasets]="_numbers" [labels]="_labels" [options]="_chartOpt" [colors]="_chartColours" [legend]="_chartLegend" [chartType]="_chartType" width="600px"&gt;
      &lt;/canvas&gt;
  &lt;div&gt;
  </code></pre>
  
  <p>The <code>app.component.ts</code></p>
  
  <pre><code>import { Component } from '@angular/core';
  import { BaseChartDirective } from "ng2-charts/ng2-charts";
  
  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
  })
  export class AppComponent {
    private _numbers: any[] = [
        {
          label: "Test",
          data: [10,2,6,7] // should cause 4 points in the chart
       }
    ];
  
    private _chartOpt: any = {
          responsive: true
    };
  
    public _chartColours:any[] = [];
  
    private _labels: string[] = [];
    private _chartLegend: boolean = false;
    private _chartType: string = "line";
  }
  </code></pre>
  
  <p>The <em>chart.js</em> library is added via the <code>angular-cli.json</code>:</p>
  
  <pre><code>"scripts": [
           "../node_modules/chart.js/dist/Chart.bundle.min.js"
        ],
  </code></pre>
  
  <p>I really don't know where I'm going wrong. I've tried many different options (<code>responsive: true/false</code>, <code>maintainAspectRatio : true/false</code>, wrapping the <code>&lt;canvas&gt;</code> in <code>&lt;div&gt;</code> and without, CSS Styles, width/height attributes, ...) but can't seem to get this one to work. I even downgraded the ng2-charts version to one that I reviously worked with, but with no luck.</p>
  
  <p>Let me know if you need anymore code.</p>
