Jqplot & JSON data from Ajax Request

Jqplot & JSON data from Ajax Request

Hi,
I wolud like to have jqplot graph with actual data beside on user choose in select (html element- alias comobobx).
I found this working example (from this thread), but still can not understand, why my code doesn't work:
http://jsfiddle.net/A24cm/

edit: problem is, that data must be vartype array, not string... but how to build array on returning string?
data.split(';').each(function(){ ... new Array(left, right) });


¯\_(ツ)_/¯
