Javascript 无法读取属性google图表

我想通过JSON设置google图表，但目前它不起作用。该网页无法读取未定义的“1”属性。如何解决这个问题？提前感谢这是我的代码：

测试目的：（模型）

控制器：

    public function getProjects(){
    $this->load->model('mreport');
    $results = $this->mreport->getBilling();
    echo json_encode($results);

}

$PR = $CO = $IN = $SP = $SC = 5;

$table['rows'] = array();
$temp = array();
$temp[] = array('v' => 'PR');
