Data visualization is the graphical display of information and data utilizing graphic components such as charts, graphs, and so on to tell captivating tales. Furthermore, if your website is data-intensive, you’ll need to figure out how to make that data easy to understand. There are a few libraries out there that can assist us in producing beautiful results with no effort, including Chart. One of them is chart js. After all, humans aren’t great at comprehending long lists of numbers. That’s where an Angular chart comes in: it can make even the most convoluted data correlations clear and intuitive, as well as more accessible to non-English speakers. As a result, developers must understand how to use chart js in Angular. Basic charts are understood by everyone at the same rate, while technical jargon-filled texts are not. Charts will make your website easier to grasp and more visually appealing when used correctly. Naturally, in this article, we’ll look at Angular charts, how to use Chart Js in this tutorial, and the finest framework for creating charts. So let’s get started.

What is Chart js?

how to use chart js in Angular on pc Chart js is a free JavaScript toolkit that makes it simple to create animated and responsive charts for your website. Chart js is a popular open-source data visualization toolkit developed by the community. It allows us to create responsive bar charts, pie charts, line plots, donut charts, scatter plots, and other graphs. Simply select where on your page you want a graph to appear, what type of graph you want to plot, and then provide data, labels, and other options to Chart js. After that, the library will do all the heavy lifting for you! It’s easy to pick up Chart js. It’s supposed to be simple, but it’s also incredibly customizable. Charting libraries, in my experience, lay on a spectrum of complexity, with more complicated libraries offering greater customization but having steeper learning curves. Chart js is one of the most straightforward libraries to learn, with few restrictions. It also includes eight different chart formats, which should satisfy practically all of your data visualization requirements. It is also available for use in React, which you can learn more about here.

How to Create a Chart in Angular Using Chart js?

Step 1 – What are Some Prerequisites Required to Create Charts?

To complete this tutorial, you will need:
  • You should have Node.js installed locally.
  • This requires you to install Angular  on your computer. You should also know about setting up an Angular project and using Angular components.

Step 2 – How to Setup the Project?

For this step, you can use @angular/cli to create a new Angular project. After this, in your terminal window, type the following command:  npx @angular/cli new angular-chartjs-example --style=css --routing=false --skip-tests The above command configures a new Angular project. The command set styles to “CSS,” with no routing and skipping tests. Next, navigate to the directory of the newly created project: cd angular-chartjs-example Now, run the following command: npm install [email protected] [email protected] This will install Chart js. The next step will be to add Chart js to your Angular application. This is Chart js by opening the angular.json file in your code editor and modifying it to add Chart.min.js. Take a look at the contents of the angular.json file below: {   // ...   "projects": {     "angular-chartjs-example": {       // ...       "architect": {         "build": {           // ...           "options": {             // ...             "scripts": [               "node_modules/chart.js/dist/Chart.min.js"             ],             "allowedCommonJsDependencies": [               "chart.js"             ]           },           // ...         },       }     }},   // ... Finally, open the app.module.ts in your editor and modify the file to include ChartsModule import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { ChartsModule } from 'ng2-charts'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, ChartsModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { } With all this inplace, you can start work on the chart component.

Step 3 – What Should you do to Create the Chart Component?

Let us now create a Chart Component. In this example, we will be constructing a line graph for time-series data. So, Open up your code editor and open the app.component.html file. Next modify this file into: <div style="width: 40%;"> <canvas baseChart > </canvas> </div> Next, in the same file modify the canvas to include a legend and chartType: <div style="width: 40%;"> <canvas ... [chartType]="'line'" [legend]="true" > </canvas> </div> But what does chartType and legend do? chatType allows you to set the base type of your chart. It can either be set to pie, bar, line, polarArea, radar, doughnut, or horizontalBar. The legend is a boolean value that specifies whether the legend should be displayed in the chart. Now, modify the canvas to pass in your datasets, add in your labels, and your options: <div style=”width: 40%;”> <canvas … [datasets]=”chartData” [labels]=”chartLabels” [options]=”chartOptions” > </canvas> </div> Finally, open app.component.ts in your editor and define the array your referenced in the template. Moreover, add in you chart labels and the object referenced : // ... export class AppComponent { // ... chartData = [ { data: [330, 600, 260, 700], label: 'Account A' }, { data: [120, 455, 100, 340], label: 'Account B' }, { data: [45, 67, 800, 500], label: 'Account C' } ]; chartLabels = [ 'January', 'February', 'March', 'April' ]; chartOptions = { responsive: true }; } You can visit the official Chart js documentation [1] to learn more about the available chart options. Finally, recompile your application using the following command: npm start You can now visit localhost:4200 to observe the chart you’ve drawn.
