Неправильно выводит AmSerialChart,в чём проблема?

jQuery(function() {
	 AmCharts.ready(function () {
		 var chart = new AmCharts.AmSerialChart();
		 chart.dataProvider = [
<?php
// very complex query that looks scarrryyyyyy
$z = 0;
$fetchUsers = $odb->query("
 SELECT
 DAY(FROM_UNIXTIME(date)) as `day`,
 DAYNAME(FROM_UNIXTIME(date)) as `dayname`,
 COUNT(*) as `boots`
 FROM `logs`
 WHERE `date` >= UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 7 DAY))
 GROUP BY DAY(FROM_UNIXTIME(date)), DAYNAME(FROM_UNIXTIME(date))
 ORDER BY `date` ASC
");

while ($row = $fetchUsers->fetch(PDO::FETCH_ASSOC)) {
 echo "{'date':'" . $row['dayname'] . " (" . $row['day'] . ")','boots':'" . $row['boots'] . "'}";
 if ($z <= 7) echo ",";
 $z++;
}
if ($fetchUsers->rowCount() <= 7) {
 for ($i = 0; $i < 7-$fetchUsers->rowCount(); $i++) {
