Morris.js文件数据

I am using mysql for data and then i get them with php...

$array = data()->query("SELECT DATE(rezervacijaOpravljena) d, COUNT(id) visits FROM rezervacija GROUP BY d")->fetchAll(PDO::FETCH_ASSOC);
echo json_encode($array,JSON_NUMERIC_CHECK);    

Than in javascript (morris.js data) i am using following script:

Morris.Line({         
    element: 'morris-line-chart',
    data:  $.ajax({             
            url: "dodajRezervacijo.php",
            success: function(html) {
            console.log(JSON.parse(html)[0]);   

            return JSON.parse(html)[0];         
            }
            })
        ,       
    // The name of the data record attribute that contains x-visitss.
    xkey: 'd',
    // A list of names of data record attributes that contain y-visitss.
    ykeys: ['visits'],
    // Labels for the ykeys -- will be displayed when you hover over the
    // chart.
    labels: ['Visits'],
    // Disables line smoothing
    smooth: true,
    resize: true
});    

But it is not working. I am a beginner in using ajax. Also is such use of php quering data good? or is better to have all things like(prepare and execute function separetly?)?

Get the data from your ajax call and in the success function call the morris graph.

That should do the trick.
