Constructing Dynamic Radar Charts in Laravel Using Chart.js: A Step-by-Step Guide

2 min readNov 29, 2023

Radar charts provide an insightful way to represent multivariate data in a radial format.
In this tutorial, we’ll guide you through integrating Chart.js into your Laravel application to create dynamic and interactive radar charts.


Before you begin, ensure the following prerequisites are met:

  1. A Laravel project is set up.
  2. Basic knowledge of Laravel and JavaScript.
  3. Composer is installed for Laravel dependencies.

Step 1: Install Chart.js via CDN

Include Chart.js in your Laravel project by adding the following CDN link in the <head> section of your blade view:

<!DOCTYPE html>
<html lang="en">
<!-- Other head elements -->
<script src=""></script>
<!-- Your Laravel application content -->

Step 2: Create a Controller

Generate a controller to handle the radar chart data. Run the following Artisan command:

php artisan make:controller RadarChartController

Step 3: Define Routes

In your routes/web.php file, define a route for the radar chart controller:

use App\Http\Controllers\RadarChartController;

Route::get('/radar-chart', [RadarChartController::class, 'radarChart']);

Step 4: Implement the Controller

Open RadarChartController.php and implement the controller logic:


namespace App\Http\Controllers;
use Illuminate\Http\Request;

class RadarChartController extends Controller
public function radarChart()
// Replace this with your actual data retrieval logic
$data = [ 'labels' => ['Category A', 'Category B', 'Category C', 'Category D', 'Category E'],
'data' => [25, 30, 15, 10, 20],
return view('radar-chart', compact('data'));

Step 5: Create a Blade View

Create a new Blade view file (resources/views/radar-chart.blade.php) to render the radar chart:

<!DOCTYPE html>
<html lang="en">
<title>Radar Chart Example</title>
<script src=""></script>
<div style="width: 80%; margin: auto;">
<canvas id="radarChart"></canvas>

var ctx = document.getElementById('radarChart').getContext('2d');
var myChart = new Chart(ctx, {
type: 'radar',
data: {
labels: @json($data['labels']),
datasets: [{
label: 'Data',
data: @json($data['data']),
backgroundColor: 'rgba(75, 192, 192, 0.2)',
borderColor: 'rgba(75, 192, 192, 1)',
borderWidth: 1
options: {
scales: {
r: {
suggestedMin: 0,
suggestedMax: 50


Congratulations! You’ve successfully integrated Chart.js into your Laravel application to create dynamic radar charts. Explore additional customization options provided by Chart.js to enhance the visual appeal of your radar charts. Happy charting!

Note: As in the previous examples, replace the static data in the controller with dynamic data fetched from your database or external API for a real-world scenario.
