graph — Fusion Charts с использованием переполнения стека

Я пытаюсь сгенерировать график в php, используя набор данных. Это многолинейный график, т.е. у меня есть 3 оператора: GP, BL, ROBI. Я могу генерировать строки для двух операторов, но третья строка не генерируется для оператора.
Вот что я попробовал:

$smarty = new Smarty();

if($year == "")
{
$year="2014";
}

$strpaid = "SELECT DATE_FORMAT(sdate, '%Y-%m') AS tdate,operator,sum(total_revenue) AS TotalRevenue FROM tbl_revenue_opr GROUP BY operator,tdate";

//$strfree = "SELECT sum(total_revenue) AS TotalRevenue, DATE_FORMAT(sdate, '%Y-%m') AS tdate FROM funstore_mis.tbl_revenue_opr GROUP BY tdate";

//echo $strpaid; echo $strfree; exit;
$resultpaid = mysql_query($strpaid) or die('Error:'.mysql_error());

//$year = "2012";
$year1 = $year."-01";
$year2 = $year."-02";
$year3 = $year."-03";
$year4 = $year."-04";
$year5 = $year."-05";
$year6 = $year."-06";
$year7 = $year."-07";
$year8 = $year."-08";
$year9 = $year."-09";
$year10 = $year."-10";
$year11 = $year."-11";
$year12 = $year."-12";
$c1 = "0099FF";
$c2 = "FF8000";
$c3 = "008000";
$c4 = "FB8000";

//$File2 = "downloadsmanth.xml";
//$Handle2 = fopen($File2, 'w');
$manthXML ="<graph caption='Total Revenue' xAxisName='Month' yAxisName='Revenue' bgColor='F1f1f1' showLegend='1' decimalPrecision='0' showNames='1' showValues='1' pieFillAlpha='70' pieSliceDepth='15' pieRadius='100' baseFontSize='12' rotateNames='1' formatNumberScale='0'>";

Пожалуйста, скажите, где я иду не так! Спасибо !!
