Step 1 : Install Laravel for Dynamic Bar Chart Example 

Run below command in terminal to create new project in laravel.

 Step 2 : Add Migration Table

Here, we required dynamic data for bar chart example so, we will create migration for "product" table using laravel php artisan command.

php artisan make:migration create_products_table --create=products

Now, make changes in migration file in this location "database/migrations".

<?php

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

class CreateProductTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('product', function (Blueprint $table) {
            $table->id();
            $table->string('name')->nullable();
            $table->integer('price')->nullable();
            $table->integer('year')->nullable();
            $table->string('product_type')->nullable();
            $table->timestamps();
        });
    }

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

Now, run this migration using below command.

php artisan migrate

 

Step 3: Add Route

Route::get('barchart', '[email protected]');

use App\Http\Controllers\Admin\BarchartController;

Route::get('barchart', [BarchartController::class,'barchart']);

 

php artisan make:model Product

 

Add below code in your controller.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Product;

class BarchartController extends Controller
{
    public function barchart(Request $request)
    {
    	$fruit = Product::where('product_type','fruit')->get();
    	$veg = Product::where('product_type','vegitable')->get();
    	$grains = Product::where('product_type','grains')->get();
    	$fruit_count = count($fruit);    	
    	$veg_count = count($veg);
    	$grains_count = count($grains);
    	
    	return view('barchart',compact('fruit_count','veg_count','grains_count'));
    }
}
