After Import chartsModule, declare the charts module in imports array.

import { BrowserModule } from '@angular/platform-browser';

import { ErrorHandler, NgModule } from '@angular/core';

import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';

import { ChartsModule } from 'ng2-charts';

import { MyApp } from './app.component';

import { HomePage } from '../pages/home/home';

import { ListPage } from '../pages/list/list';

import { LoginPage } from '../pages/login/login';

import{ RegisterPage } from '../pages/register/register';

import{ UsersPage } from '../pages/users/users';

import { StatusBar } from '@ionic-native/status-bar';

import { SplashScreen } from '@ionic-native/splash-screen';

@NgModule({

declarations: [

MyApp,

HomePage,

ListPage,

LoginPage,

RegisterPage,

UsersPage

imports: [

BrowserModule,

IonicModule.forRoot(MyApp),

ChartsModule

bootstrap: [IonicApp],

entryComponents: [

MyApp,

HomePage,

ListPage,

LoginPage,

RegisterPage,

UsersPage

providers: [

SplashScreen,

{provide: ErrorHandler, useClass: IonicErrorHandler}

]

})

export class AppModule {}

After declare the charts module in imports array, add the charts HTML code in your Apps,

Home.html –

<canvas baseChart height="350"

[datasets]="lineChartData"

[labels]="lineChartLabels"

[options]="lineChartOptions"

[colors]="lineChartColors"

[legend]="lineChartLegend"

[chartType]="lineChartType"

(chartHover)="chartHovered($event)"

(chartClick)="chartClicked($event)"></canvas>

</div>

Home.ts

import { Component } from '@angular/core';

import { NavController } from 'ionic-angular';

@Component({

selector: 'page-home',

templateUrl: 'home.html'

})

export class HomePage {

constructor(public navCtrl: NavController) { }

//line Chart Data

public lineChartData:Array<any> = [

{data: [65, 59, 80, 81, 56, 55, 40], label: 'Series1'},

{data: [28, 48, 40, 19, 86, 27, 90], label: 'Series2'},

{data: [18, 48, 77, 9, 100, 27, 40], label: 'Series3'}

];

public lineChartLabels:Array<any> = ['January', 'February', 'March', 'April', 'May', 'June', 'July'];

public lineChartOptions:any = {

responsive: true

};

public lineChartLegend:boolean = true;

public lineChartType:string = 'line';

public lineChartColors:Array<any> = [

{

backgroundColor: 'rgba(148,159,177,0.2)',

borderColor: 'rgba(148,159,177,1)',

pointBackgroundColor: 'rgba(22,15,17,1)',

pointBorderColor: '#fff',

pointHoverBackgroundColor: '#fff',

pointHoverBorderColor: 'rgba(148,159,177,0.8)'

{

backgroundColor: 'rgba(23,33,33,0.2)',

borderColor: 'rgba(77,83,96,1)',

pointBackgroundColor: 'rgba(77,83,96,1)',

pointBorderColor: '#fff',

pointHoverBackgroundColor: '#fff',

pointHoverBorderColor: 'rgba(77,83,96,1)'

{

backgroundColor: 'rgba(148,159,177,0.2)',

borderColor: 'rgba(148,159,177,1)',

pointBackgroundColor: 'rgba(148,159,177,1)',

pointBorderColor: '#fff',

pointHoverBackgroundColor: '#fff',

pointHoverBorderColor: 'rgba(148,159,177,0.8)'

}];

// Chart events

public chartClicked(e:any):void {

console.log(e);

}

// Chart events
