angular - easy pie chart not appearing in ionic 2

Question

I am using NPM ng2modules-easypiechart for ionic project

Import the module app.maodule.ts

import { EasyPieChartModule } from 'ng2modules-easypiechart';
imports: [
  EasyPieChartModule
]

I am using the easyPieChart directive in my component template but the chart is not appearing.

Html

<easy-pie-chart [percent]="percent" [options]="options"></easy-pie-chart>

Component

import 'easy-pie-chart/dist/easypiechart.js';

@Component({
   selector: 'page-transactiontype',
   templateUrl: 'TransactionDetails.html'
})
export class TransactionDetails {
  public percent: number;
  public options: any;

  constructor() {
     this.percent = 80;
     this.options = {
       barColor: '#ef1e25',
       trackColor: '#f9f9f9',
       scaleColor: '#dfe0e0',
       scaleLength: 5,
       lineCap: 'round',
       lineWidth: 3,
       size: 110,
       rotate: 0,
       animate: {
          duration: 1000,
          enabled: true
       }
     };
   }
 }
