As a beginner in learning highchart, I cannot find out why the chart cannot display in the view. My controller displays the json data properly but when I call the controller in the $.getJSON to display the data in the chart I got a blank page.

Can someone help me to make the chart display in the View ?

Thanks

My controller

public function chartBarData() 

$query1 = $this->model_admin->getBarCha1('2019-01-24','2019-01-25');
$category = array();
$category['name'] = 'Medico';

$series1 = array();
$series1['name'] = 'Paciente';


foreach ($query1 as $row)

$category['data'][] = $row->Medico;
$series1['data'][] = $row->Paciente;



$result = array();
array_push($result,$category);
array_push($result,$series1);


print json_encode($result, JSON_NUMERIC_CHECK);

print json_encode($result, JSON_NUMERIC_CHECK) result :

["name":"Medico","data":["baptiste prophete","JUAN ALBERTO SUERO","ADRIANA MATEO","RAUL ARISTY COMAS","VICTORIA LILA FRANCO","IVANHOE LINARES VENTURA"],"name":"Paciente","data":[2,3,15,13,1,6]]

The view
