This is what I am doing with Highcharts. Wierd thing is my friend used this exact code and my table and it worked fine but when I added it to a view i get:
PHP Error
Undefined variable: final_results
If I intialize $final_results = array(); I get Undefined offset: 0
Can’t seem to win… lol 
I thought I beat this thing.
<?php
$sql = "SELECT DATE_FORMAT( completion_date, '%b' ) AS name, COUNT( * ) AS data FROM `pms` AS p WHERE completion_date > schduled_date AND completion_date != '0000-00-00' GROUP BY name LIMIT 0 , 30";
$connection = Yii::app()->db;
$command = $connection->createCommand($sql);
$results = $command->queryAll();
$months = array('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec');
$x=0;
for($r=0;$r<3;$r++){
for($m=0;$m<12;$m++){
if (strcmp($results[$r]['name'], $months[$m]) == 0){
$final_results[$m] += (integer)$results[$r]['data'];
}
else{
$final_results[$m] += 0;
}
//echo $results[$r]['name'];
}
//$final_name[$r]['name'] = $results[$r]['name'];
}
$final_data[0] = array('name' => 'Result', 'data' => $final_results);
echo '<br/>';
//print_r($final_data);
//$pms->
$this->Widget('ext.highcharts.HighchartsWidget', array(
'options'=>array(
'series' => $final_data
,
'title' => array('text' => 'Fruit Consumption'),
'xAxis' => array(
'categories' => $months
),
'yAxis' => array(
'title' => array('text' => 'Fruit eaten')
),
/* 'series' => array(

array('name' => 'Paul', 'data' => array(11, 10, 14)),

array('name' => 'John', 'data' => array(5, 7, 3))
)*/
//'series' => $results
)
));
?>
Here is the error I am getting:
