Quelqu'un peut-il me aider avec le graphique PHP?

Question

Je suis en train d'afficher total Montant de la commande par jour dans le présent mois.

$sql = "SELECT date(order_placed_date), 
               COUNT(order_id), 
               SUM(order_total) AS order_total 
        FROM orders 
        WHERE order_placed_date>=date_sub(current_date, INTERVAL 31 DAY) 
        GROUP BY date(order_placed_date)";

if (!$sql) die('Invalid query: ' . mysql_error());

$result = mysql_query($sql);
$data = array();
while($row = mysql_fetch_array($result))
{
  $data[] = intval($row['order_total']);
}

/*
 *  Create a title object and set the text to present month.
 */
$title = new title('Monthly Sales Statistics for '.date("F Y").' (US Dollar)');
$title->set_style( "{font-size: 18px; 
                     font-family: Calibri; 
                     color: #808000; 
                     text-align: center;}" );

//Make our Bar Chart
$bar = new bar_filled('#f99bd6', '#ee0099');
$bar->set_values($data);

//Create a new Chart object
$chart = new open_flash_chart();

// add the title to the chart:
$chart->set_title( $title );
$chart->set_bg_colour("#FFFFFF");

// Display the bar object on the chart
$chart->add_element($bar);

// create an X Axis object
$x = new x_axis();

// grid line and tick every 10
$x->set_range(
    mktime(0, 0, 0, 7, 1, date('Y')),    // <-- min == 1st Jan, this year
    mktime(0, 0, 0, 7, 31, date('Y'))    // <-- max == 31st Jan, this year
    );

// show ticks and grid lines for every day:
$x->set_steps(86400);

$labels = new x_axis_labels();

// tell the labels to render the number as a date:
$labels->text('#date:j #');

// generate labels for every day
$labels->set_steps(86400);

// only display every other label (every other day)
$labels->visible_steps(1);

// finally attach the label definition to the x axis
$x->set_labels($labels);


//Create a Y Axis object
$y_axis = new y_axis();
$y_axis->set_range(1, 15000, 1000);

//Add the y-axis object to the chart
$chart->add_y_axis($y_axis);
$chart->set_x_axis( $x );
echo $chart->toPrettyString();
?>

Voici ce que je reçois:

Quelqu'un peut-il me dire où est le problème et comment la corriger?

Voici la sortie print_r($data):

Voici la sortie de print_r($data)

Array

    [0] => 7721
    [1] => 2169
    [2] => 2249

    [28] => 0
    [29] => 0
    [30] => 0
)

J'ai changé la boucle while:

for( $i=1; $i<32; $i++ )
{
    $row = mysql_fetch_array($result);    
    $data[] = intval($row['order_total']);
}

Voici le graphique mis à jour lors de l'utilisation ci-dessus pour la boucle: texte alt http://static.zooomr.com/images/7807811_1b3c7c7274_o.png
