why highchartis giving different results with similar data structure?

Yii 1.1 General Discussion

I am using high chart in my yii based application.

after querying the database I am storing the result in a associative array named $catexp

after printing the structure using print_r($catexp) I am getting follwing


Array ( [0] => Array ( [name] => Food [y] => 91 ) [1] => Array ( [name] => Utilities [y] => 9 ) )

now this the structure of data which can be passed to highcart for generating pie chart.

but after passing this $catexp as data for pie chart I am getting wired output i.e. i am not getting the full chart

although i made a similar manual array structure like this


$a = array('name'=> 'Opera','y'=>91);

        $b = array('name'=> 'Safari','y'=>9);

    	$c = array($a,$<img src='http://www.yiiframework.com/forum/public/style_emoticons/default/cool.gif' class='bbc_emoticon' alt='B)' />;

print_r($c) gives


Array ( [0] => Array ( [name] => Opera [y] => 91 ) [1] => Array ( [name] => Safari [y] => 9 ) )

and passed this variable as data for pie chart and i got the full chart.

So my question is what is wrong with my previous chart both the array structures are same but output is diff?????

finally i found the bug why i am not getting the full data… it is because the $catexp array contain the ‘y’ value in string format which should be number and because of this i was getting error so i used a foreach loop and converted the ‘y’ values to double like




$i = 0;

foreach ($catexp as $key => $value)

{

$c[]=array($catexp[i]['name'], (double)$catexp[i]['y']);

}

and then i am passing $c as data to piechart and i am getting desired output.

hope somw day it will help you…
