How to Implement Google line Chart using Codeigniter – onlinecode
In this post we will give you information about How to Implement Google line Chart using Codeigniter – onlinecode. Hear we will give you detail about How to Implement Google line Chart using Codeigniter – onlinecodeAnd how to use it also give you demo for it if it is necessary.
In this article, we will explain to you how to Implement Google line Chart using Codeigniter. today we will fetch data into MySQL, and plot a Line graph.
There are many types of charts provide by Google, like a bar chart, area chart, line chart, pie chart, etc. but here we use a Line chart.
In this article, we will plot a line graph using Google API. so you can see below the following steps.
Overview
Step 1: Create a Database in tableStep 2: Connect to DatabaseStep 3: Create ControllerStep 4: Create View File
Step 1: Create a Database in tableIn this step, we have to create a table in the database, so we will create a database using the below code.
CREATE TABLE 'login_history' (
'id' int(11) NOT NULL,
'user_id' int(11) NOT NULL,
'login_date' timestamp NOT NULL DEFAULT current_timestamp() ON UPDATE current_timestamp(),
PRIMARY KEY ('id')
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 AUTO_INCREMENT=1;Step 2: Connect to DatabaseGo to the config folder and open database.php file some changes in this file like hostname, database username, database password, and database name.
$db['default'] = array( 'dsn' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'enter here database name', 'dbdriver' => 'mysqli', 'dbprefix' => '', 'pconnect' => FALSE, 'db_debug' => (ENVIRONMENT !== 'production'), 'cache_on' => FALSE, 'cachedir' => '', 'char_set' => 'utf8', 'dbcollat' => 'utf8_general_ci', 'swap_pre' => '', 'encrypt' => FALSE, 'compress' => FALSE, 'stricton' => FALSE, 'failover' => array(), 'save_queries' => TRUE );
Step 3: Create ControllerIn this step, we will create a Googlechart.php file in the “application/controller” directory and paste the below code in this controller. here we will fetch data Day Wise Count Login Users Of Current Month from the database. that data will be pass in a chart and creating a Line graph.application/controller/Googlechart.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Googlechart extends CI_Controller {
public function __construct() {
parent::__construct();
// load model
$this->load->database();
$this->load->helper(array('url','html','form'));
}
public function line_chart() {
$query = $this->db->query('SELECT DATE_FORMAT(login_date, "%Y-%m-%d") AS 'date', COUNT('login_date') as count FROM login_history WHERE MONTH(login_date) = "' . date('m') . '" AND YEAR(login_date) = "' . date('Y') . '" GROUP BY DAY(login_date)');
$records = $query->result_array();
$data['chart_data'] = $records;
$this->load->view('line_chart',$data);
}
}
?>Step 4: Create View FileSo finally, we will create the line_chart.php file in the “application/views/” directory.application/views/line_chart.php
