Charts outside of reports page

[stuntnmore]

Im trying to show charts within a tpl file within a custom admin page in whmcs

 

This is what i have tried

 

{php}
$counter = mysql_query("SELECT COUNT(*) AS id FROM tblclients WHERE status='Active'");
$num = mysql_fetch_array($counter);
$count = $num["id"];
$this->assign('clienttotal',$count); 

$counter2 = mysql_query("SELECT COUNT(*) AS id FROM tbldomains WHERE status='Active'");
$num2 = mysql_fetch_array($counter2);
$count2 = $num2["id"];
$this->assign('domaintotal',$count2); 

$counter3 = mysql_query("SELECT COUNT(*) AS id FROM tblhosting WHERE domainstatus='Active'");
$num3 = mysql_fetch_array($counter3);
$count3 = $num3["id"];
$this->assign('hostingtotal',$count3); 
{/php}
{php}
$reportdata["monthspagination"] = true;

$reportdata["tableheadings"] = array(
   "Date",
   "Completed Orders",
   "New Invoices",
   "Paid Invoices",
   "Opened Tickets",
   "Ticket Replies",
   "Cancellation Requests",
);

$reportvalues = array();
$query = "SELECT date_format(date, '%e'),COUNT(id) FROM tblorders WHERE date LIKE '" . $year . "-" . $month . "-%' AND status='Active' GROUP BY date_format(date, '%e') ORDER BY date ASC";
$result = full_query($query);
while ($data = mysql_fetch_array($result)) {
   $reportvalues['orders_active'][$data[0]] = $data[1];
}
$query = "SELECT date_format(date, '%e'),COUNT(id) FROM tblinvoices WHERE date LIKE '" . $year . "-" . $month . "-%' GROUP BY date_format(date, '%e') ORDER BY date ASC";
$result = full_query($query);
while ($data = mysql_fetch_array($result)) {
   $reportvalues['invoices_new'][$data[0]] = $data[1];
}
$query = "SELECT date_format(datepaid, '%e'),COUNT(id) FROM tblinvoices WHERE datepaid LIKE '" . $year . "-" . $month . "-%' GROUP BY date_format(datepaid, '%e') ORDER BY datepaid ASC";
$result = full_query($query);

$result = full_query($query);
while ($data = mysql_fetch_array($result)) {
   $reportvalues['cancellations_new'][$data[0]] = $data[1];
}

for ($day = 1; $day <= 31; $day++) {

   $date = date("Y-m-d", mktime(0, 0, 0, $month, $day, $year));
   $daytext = date("l", mktime(0, 0, 0, $month, $day, $year));

   $neworders = isset($reportvalues['orders_active'][$day]) ? $reportvalues['orders_active'][$day] : '0';

   $cancellations = isset($reportvalues['cancellations_new'][$day]) ? $reportvalues['cancellations_new'][$day] : '0';

   $reportdata["tablevalues"][] = array(
       $daytext.' '.fromMySQLDate($date),
       $neworders,
       $newinvoices,
       $paidinvoices,
       $newtickets,
       $ticketreplies,
       $cancellations,
   );

   $chartdata['rows'][] = array(
       'c'=>array(
           array('v' => fromMySQLDate($date)),
           array('v' => (int)$neworders),
           array('v' => (int)$newinvoices),

           array('v' => (int)$newtickets),
           array('v' => (int)$ticketreplies),
           array('v' => (int)$cancellations)
       )
   );

}

$chartdata['cols'][] = array('label'=>'Day','type'=>'string');
$chartdata['cols'][] = array('label'=>'Completed Orders','type'=>'number');
$chartdata['cols'][] = array('label'=>'New Invoices','type'=>'number');
$chartdata['cols'][] = array('label'=>'Paid Invoices','type'=>'number');
$chartdata['cols'][] = array('label'=>'Opened Tickets','type'=>'number');
$chartdata['cols'][] = array('label'=>'Ticket Replies','type'=>'number');
$chartdata['cols'][] = array('label'=>'Cancellation Requests','type'=>'number');

$args = array();
$args['legendpos'] = 'right';

$reportdata["headertext"] = $chart->drawChart('Area',$chartdata,$args,'400px');

{/php}

 

Everything is correct but i recieve an error when trying to execute,

Fatal error: Call to a member function drawChart() on a non-object in 217
