Integrating Chart.js with Angular can take an app not only better looking but more interactive user-wise than half of Italy. While this article will guide you through that process, we also show ways to optimize performance and check over your finished production: In addition, the end of the article briefly summarizes 3 sites offering online tools that can help with your Angular apps SEO work (for those interested in such information).

Why Choose Chart.js for Angular?

To provide a little background before we dive into the nitty-gritty technical details, why should Angular developers choose Chart.js?

1. Lightweight & Simple: Chart.js provides developers with a fast, low-footprint library to produce interactive, responsive, and lightweight-resolution byte charts.
2. Responsive Design: All these charts will spy for click events while automatically adjusting to whatever screen size and display medium they are being asked, ensuring that your visual data looks as good on a 220cm screen as it does with the screen a little over 10cm wide.
3. Wide Range of Chart Types: From line graphs and bar charts to scatter plots and pie graphs, Chart.js has a very rich assortment of more than 6 types for you to choose from depending on what you are looking at.
4. Customizable: You can customize everything from colors and fonts to animation effects according to your app’s demand.
5. Active Community Support: With a large development community involved in its development process, Chart.js is designed to be easily referable and constantly updated.

Getting Started with Chart.js in Angular

For you to start using Chart.js in Angular, there are four steps:

1. Self-Learning of ng Chart and Chart.js

To start, make sure If you don’t have Angular CLI yet, you can do so via npm command line:

npm install -g @angular/cli

Next, create an Angular project or navigate to your existing project folder:

ng new angular-chartjs-app
cd angular-chartjs-app

After that, install Chart.js and ng2-charts, which is a library that wraps Chart.js for use with Angular:

npm install chart.js ng2-charts

2. ChartModule Introduction in Your Angular App

After the installation is complete, import ChartsModule from ng2-charts into your Angular module (app.module.ts):

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { ChartsModule } from 'ng2-charts';

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

@NgModule({
declarations: [
  AppComponent
],
imports: [
  BrowserModule,
  ChartsModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }

3. Basic Creation of Chart Component

Now that you have already laid the foundation, let us present a simple bar chart component. In your app.component.html, add the following code:

<div style="display: block;">
  <canvas baseChart
    [datasets]="barChartData"
    [labels]="barChartLabels"
    [options]="barChartOptions"
    [legend]="barChartLegend"
    [chartType]="barChartType">
  </canvas>
</div>

Then in your app.component.ts, load the data and provide options for the chart:

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

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
  public barChartOptions = {
    scaleShowVerticalLines: false,
    responsive: true
  };
  public barChartLabels = ['January', 'February', 'March', 'April', 'May', 'June', 'July'];
  public barChartType = 'bar';
  public barChartLegend = true;

  public barChartData = [
    { data: [65, 59, 80, 81, 56, 55, 40], label: 'Series A' },
    { data: [28, 48, 40, 19, 86, 27, 90], label: 'Series B' }
  ];
}

4. Running Your Angular App

Finally, compile your Angular application to see the bar chart you’re working on in action:

ng serve

1. Line Chart: [type]="'line'"  
2. Pie Chart: [type]="'pie'"  
3. Dynamic Updates: Use Angular’s ngOnChanges to refresh data dynamically.

Integrating Chart.js with Angular is a powerful way to explode your soft and hard information visualisation functions. If you follow this guide, you will be able to easily construct brief, self-explanatory bar charts that can be interacted with.

Chart.js and Angular are a perfect match for dashboards, analytics platforms, and other apps that make heavy use of data. Test out different chart types, customization options, and performance improvements today!
