title: Dynamically updated ng2-charts
body: <p>Is it possible to update any <code>chart</code> from <code>ng2-charts</code> dynamically? I know there are other libraries like <code>angular2-highcharts</code>, but I would like to handle it using <code>ng2-charts</code>. Main question is how can I redraw <code>chart</code>, after button click? I can resize window and data will be updated, so it have to be any option to do it manually.</p>
