Always try to use latest version of Highcharts. If you will use 3.07 version, you will have in javascript console explanation why your chart doesn't work. Culprit is that your data contains strings, while should be numbers:

    "data": ["4", "0", "44", "3" ...]

While should be:

    "data": [4, 0, 44, 3 ...]

Error reference.

You are very right @Pawel, but when i am passing array to Highchart php like this way `$chart->series[] = array( 'name' => 'name99', 'data' => $chartArr[1] );` it automatically adding double quotes on array value. – Dec 05 '13 at 06:03
Use `json_encode()`. There is a lot of example for it over SO ;) Like [this one](http://stackoverflow.com/questions/13523729/how-to-json-encode-php-array-but-the-keys-without-quotes). – Paweł Fus Dec 05 '13 at 10:57
