In this article, we will see how to create a dynamic pie chart in laravel. charts are used to represent data in graphics view, for the creation of a dynamic pie chart example you need to create a route, controller, blade file, and database. So, if you will follow this tutorial step by step then definitely you will get output.
So, let's see a dynamic pie chart in laravel 6 and laravel 7 or a dynamic pie chart example.
Type the following command in the terminal.
composer create-project --prefer-dist laravel/laravel echartWe need dynamic data for the pie chart example. So first, we have to create migration for the "product" table using the Laravel PHP artisan command. So, first type the below command.
php artisan make:migration create_products_table --create=productsAfter running this command you will find the PHP file here location "database/migrations/" in this file you need to add the below code.
<?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');
}
}after this, we need to run this migration by following the command in our terminal.
php artisan migrateNow, Add route in Routes/web.php
Route::get('echarts', '[email protected]');After adding the route we need to create a new controller and model so type the below command to create a controller.
php artisan make:controller EchartControllerphp artisan make:model ProductAdd the below code in the App\Http\Controllers\EchartController path.
<?php
namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;
class EchartController extends Controller
{
public function echart(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('echart',compact('fruit_count','veg_count','grains_count'));
}
}Now in this final step, we are creating an echart.blade.php file for view.
