I need to display the selected value of a donut chart.I am using codeigniter.I have written the code and got nothing in response.

DonutChart::create(array(
    "responsive"=>true,
    "dataSource"=>$orders,
    "columns"=>array(
        "type",
        "amount"=>array(
            "type"=>"number",
            "prefix"=>"$",
        )
    ),
    "clientEvents"=>array(
            "itemSelect"=>"function(params){
                console.log('click', params.selectedValue);
            }",
    )
)); 

No data is displayed in console.I need the selected value of the chart.Please help me.I need this urgently.

Hi,

Thank You so much for the solution.I have solved that problem. But I am facing problem in export to pdf.I am using codeigniter and calling the reports from controller.

I need to export the chart in to pdf and I have used instant exporter function to export.But it gives empty pdf.

Here are the functions,

public function get_cash_detail_by_date()
	{
		
		if (!$this->ion_auth->logged_in()){
			redirect('authentication/login', 'refresh');
		}

		$top_url_menu = str_replace(array("_","-"), ' ', strtolower($this->uri->segment(1)));
		$left_url_menu = $this->input->get('id');

		if(!$this->role_model->create_role_permission($top_url_menu, $left_url_menu, 'rr_update')){
			$this->session->set_flashdata('check_permission', 'You do not have permission to edit attribute');
			redirect($this->uri->segment(1) . '/'. $left_url_menu . "?menu=".$this->input->get('menu').($this->input->get('submenu')? "&submenu=".$this->input->get('submenu') : "" )."&id=".$this->input->get('id')."&dbc=1");
			return false;
		}


			unset($_SESSION["from"]);
			unset($_SESSION["to"]);
			unset($_SESSION["type"]);
			
			$from = $this->input->post('from')?$this->input->post('from'):date('Y-m-d');
			$to = $this->input->post('to')?$this->input->post('to'):date('Y-m-d');
			$type = $this->input->post('type');
			$_SESSION['from']=$from;
			$_SESSION['to']=$to;

			$from = $_SESSION['from'];
			$to = $_SESSION['to'];
			
			$values = $this->reports_model->get_cash_detail_by_date($from, $to, $type);

		//  $_SESSION['values']=$values;
		 
			$data = array(
				'title' 		=>	'Cash Report',
				'page_name' 	=>	'reports/cash_reportpdf',
				'top_menus' 	=> 	$this->menu_model->top_menu(),
				'topmenu_roles'	=> 	$this->role_model->get_user_role_for_topmenu(),
				'all_clients'	=> 	$this->user_model->client_detail(),
				'all_stores'	=> 	$this->user_model->get_all_store_details(),
				'user_roles'	=> 	$this->role_model->user_roles_detail(),
				'stores'		=>	$this->user_model->get_store_detail(),
				'menus' 		=>	$this->menu_model->menus($this->uri->segment(1)),
				'roles' 		=>	$this->role_model->get_user_role(),
				'orders1' 		=> $values
			 );

		$this->load->view('index', $data);	
			
			
	}

This is the function to display the chart in view page.

public function export(){
		
		Exporter::export($_SERVER['DOCUMENT_ROOT']."/client/clienttool/application/views/pages/reports/cash_report.php")
		->pdf(array(
			"format"=>"A4",
			"orientation"=>"portrait"
		))
		->toBrowser("myfile.pdf");
	}

This is the export function.

Can you please tell me how to achieve export to pdf option in codeigniter? Please reply me asap.

Thank You.

And there is another issue , I am trying to add link to the values of table.But it is not showing as link,it is just displaying the a href text insted.
