Hi!
I didn't quite understand why you tried to create a full response in your
javascript code.
It's hard for me right now to think of a usecase for this...
Such responses are parsed by the library's internal mechanisms when using
google.visualization.Query and such and are not meant to be used in this
way.
For this example, i would keep only the datatable part (something like
{"cols":[{"id":"user","label":
>
> "User","number":"string"},
> {"id":"title","label":"Title","number":"string"},
> {"id":"application","label":"Application","number":"string"},
> {"id":"duration","label":"Duration","number":"number"}],"rows":[{"c":
> [{"f":"string","v":"PKDEV168"},{"f":"string","v":"Some Title"},
> {"f":"string","v":"firefox.exe"},{"f":"1","v":"45"}]},{"c":
> [{"f":"string","v":"PKDEV168"},{"f":"string","v":"Some Title Part 2"},
> {"f":"string","v":"chrome.exe"},
> {"f":"1","v":"40"}]}]}
) and feed it to the constructor of google.visualization.DataTable.
Please elaborate if i didn't understand you correctly.
