bootstrap: [ AppComponent ]

})

export class AppModule { }

Step 4: Update Ts File

src/app/app.component.ts

import { Component, OnInit, ViewChild } from '@angular/core';

import { ChartDataSets, ChartOptions } from 'chart.js';

import { Color, Label } from 'ng2-charts';

@Component({

templateUrl: './app.component.html',

styleUrls: [ './app.component.css' ]

})

export class AppComponent {

public lineChartData: ChartDataSets[] = [

{ data: [61, 59, 80, 65, 45, 55, 40, 56, 76, 65, 77, 60], label: 'Apple' },

{ data: [57, 50, 75, 87, 43, 46, 37, 48, 67, 56, 70, 50], label: 'Mi' },

];

public lineChartLabels: Label[] = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'];

public lineChartOptions: (ChartOptions & { annotation: any }) = {

responsive: true,

};

public lineChartLegend = true;

public lineChartType = 'line';

public lineChartPlugins = [];

constructor() { }

ngOnInit() {

}

}

Step 5: Update HTML File

here, we need to update html file as like bellow code:

src/app/app.component.html

<h1>Angular Line Chart Example - ItSolutionStuff.com</h1>

<div style="display: block;">

<canvas baseChart width="500" height="200"
