    I get the error below when trying to use a Kendo Chart in a Angular application.

    I have installed hammerjs via npm and also loaded the library by using

    import "hammerjs";

    in my component typescript file.

    Not sure what I've missed ?

    Hi Saquib,

    This is a common error that is displayed when hammerjs is not loaded.

    As far as I understand, you have installed Hammer.js npm package and imported it in a component typescript file. However the import has to be done in appModule as shown in the following sample plunker:

    http://plnkr.co/edit/6RKIneFvEwPaPhzs35WD?p=preview

    In app/app.module.ts I have the following:

    import { NgModule }      from '@angular/core';
    import { Component } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
    import { ChartsModule } from '@progress/kendo-angular-charts';
    import { HttpModule } from '@angular/http';
     
    import 'hammerjs';
     
    import { AppComponent }   from './app.component';
     
    @NgModule({
      imports:      [ BrowserModule, BrowserAnimationsModule, ChartsModule, HttpModule ],
      declarations: [ AppComponent ],
      bootstrap:    [ AppComponent ]
    })
     
    export class AppModule { }

    I hope this helps.
