Dynamic line charts are an effective approach to visualise data trends, variations, and patterns over time. They allow users to swiftly grasp data dynamics and make data-driven decisions. Laravel, a powerful PHP framework, in conjunction with JavaScript libraries such as Highcharts, makes it simple to construct dynamic line charts.

We will walk you through the process of constructing a dynamic line chart in Laravel 10, allowing you to show and update data in an interactive and visually pleasing manner.

Throughout this article, we will look at how to build up a Laravel project, integrate Highcharts, and create dynamic line charts that can fetch and display data in real-time.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

Setup Data Model and Migration

Open project terminal and run this command,

php artisan make:model Student -m

It will create two files:

  • Model – Student.php inside /app/Models folder
  • Migration file – xxx_create_students_table.php inside /database/migrations folder.

Open migration file and write this complete code into it,

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::create('students', function (Blueprint $table) {
            $table->id();
            $table->string("name", 120);
            $table->integer("term1_marks");
            $table->integer("term2_marks");
            $table->integer("term3_marks");
            $table->integer("term4_marks");
            $table->text("remarks");
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down(): void
    {
        Schema::dropIfExists('students');
    }
};

class Student extends Model
{
    use HasFactory;

    public $timestamps = false;
}

     *
     * @return void
     */
    public function run(): void
    {
        $faker = \Faker\Factory::create();

        for ($loop = 0; $loop < 5; $loop++) {

            DB::table("students")->insert([
                "name" => $faker->name(),
                "term1_marks" => $faker->numberBetween(45, 95),
                "term2_marks" => $faker->numberBetween(45, 95),
                "term3_marks" => $faker->numberBetween(45, 95),
                "term4_marks" => $faker->numberBetween(45, 95),
