Codeigniter 4 Google Bar & Line Charts Example

In this article, we will explain to you how to integrate the google bar & line charts example in Codeigniter 4(Codeigniter 4 Google Bar & Line Charts Example). we can easily integrate the Google bar and line Chart day, week, and month-wise in CodeIgniter 4.

In this example, we are getting day wise data for google bar and line chart from MySQL in Codeigniter 4 and you can also get or use data month wise or weekly wise from MySQL. so you can see our following example.

Overview
Step 1: Download Codeigniter
Step 2: Basic Configurations
Step 3: Create a Database in table
Step 4: Connect to Database
Step 5: Create Controller
Step 6: Create Views Files
Step 7: Run The Application

Step 1: Download Codeigniter
If you want to download or install the latest version of CodeIgniter 4 then you can go to Codeigniter’s official site and download the latest version of Codeigniter 4. after the downloaded you can configure in “xampp/htdocs/” directory.

Step 2: Basic Configurations
If you want to Basic Configurations in your project then you can below Url.

Step 3: Create a Database in table
In this step, We will create the database and products table. so here we have taken some fruits name as products.

CREATE TABLE IF NOT EXISTS `products` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(255) NOT NULL,
  `sales` varchar(255) NOT NULL,
  `created_at` varchar(30) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

INSERT INTO `products` (`id`, `name`, `sales`, `created_at`) VALUES
(1, 'Apple', '2000', '2021-01-02'),
(2, 'Mango', '3000', '2021-02-03'),
(3, 'Banana', '1000', '2021-03-02'),
(4, 'Orange', '2500', '2021-04-05'),
(5, 'Apricots', '6000', '2021-05-04'),
(6, 'Cherry', '27000', '2021-06-07'),
(7, 'Jackfruit', '1600', '2021-07-05'),
(8, 'Kiwi', '1200', '2021-08-06'),
(9, 'Peach', '1200', '2021-09-02');

Step 4: Connect to Database
Go to the “app/Config/Database.php” folder and open the database.php file some changes in this file like hostname, database username, database password, and database name.

	public $default = [
		'DSN'      => '',
		'hostname' => 'localhost',
		'username' => 'root',
		'password' => '',
		'database' => 'ci4_demo',
		'DBDriver' => 'MySQLi',
		'DBPrefix' => '',
		'pConnect' => false,
		'DBDebug'  => (ENVIRONMENT !== 'production'),
		'cacheOn'  => false,
		'cacheDir' => '',
		'charset'  => 'utf8',
		'DBCollat' => 'utf8_general_ci',
		'swapPre'  => '',
		'encrypt'  => false,
		'compress' => false,
		'strictOn' => false,
		'failover' => [],
		'port'     => 3306,
	];

Step 5: Create Controller
In this step, we will create the “Chart.php” controller in “app/Controllers” directory.
app/Controllers/Chart.php

<?php 

namespace App\Controllers;
 
use CodeIgniter\Controller;
 
class Chart extends Controller
{
 
	public function __construct()
	{
		helper(['html','url']);
	}
		
	public function index() {
		$db = \Config\Database::connect();
		$builder = $db->table('products');

		$query = $builder->select("COUNT(id) as count, sales, DAYNAME(created_at) as day");
		$query = $builder->where("DAY(created_at) GROUP BY DAYNAME(created_at), sales")->get();
		$record = $query->getResult();

		$productData = [];

		foreach($record as $row) {
			$productData[] = array(
				'day'   => $row->day,
				'sell' => floatval($row->sales)
			);
		}

		$data['productData'] = ($productData);    
		return view('index', $data);     
	}
 
}

?>

Step 6: Create Views Files
Finally, we will create the index.php in the app/views directory.

app/views/index.php

	<meta name="viewport" content="width=device-width, initial-scale=1.0">

		</div>
	</div>
	<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
	<script>
		google.charts.load('current', {'packages':['corechart', 'bar']});
		google.charts.setOnLoadCallback(drawLineChart);
		google.charts.setOnLoadCallback(drawBarChart);

		// Line Chart
		function drawLineChart() {
		var data = google.visualization.arrayToDataTable([
			['Day', 'Products Count'],
				<?php 
					foreach ($productData as $row){
					   echo "['".$row['day']."',".$row['sell']."],";
				} ?>
		]);

		var options = {
			title: 'Line chart product sell wise',
			curveType: 'function',
			legend: {
				position: 'top'
			}
		};
		var chart = new google.visualization.LineChart(document.getElementById('GoogleLineChart'));
		chart.draw(data, options);
		}


		// Bar Chart
		google.charts.setOnLoadCallback(showBarChart);
		function drawBarChart() {
		var data = google.visualization.arrayToDataTable([
			['Day', 'Products Count'], 
				<?php 
					foreach ($productData as $row){
					   echo "['".$row['day']."',".$row['sell']."],";
					}
				?>
		]);
		var options = {
			title: ' Bar chart products sell wise',
			is3D: true,
		};
		var chart = new google.visualization.BarChart(document.getElementById('GoogleBarChart'));
		chart.draw(data, options);
		}
	</script>
</body>
</html>

Step 7: Run The Application
We can start the server and run the codeigniter 4 application using the below command.

php spark serve

Now we will run our example using the below Url in the browser.

http://localhost:8080/chart
