Accepted answer
the problem is that values are strings, for example, your data:
["2011-05-30 00:00:00","130"]
should be instead:
[1306706400000, 130]
to it's timestamp in ms and true value.
you can read about json_numeric_check
option for json_encode(string, json_numeric_check)
to change strings to numbers. but dates to timestamps you need to change on your own.
edit: also the problem was with setting data in doubled array, changed from:
data: [rows]
to:
data: rows
