php - Make JSON array Flot compatible -

i have php code outputs json array when $.getjson called:

. . . $data = array_combine($date_dispatched,$amount);  echo json_encode($data); 

this collected by:

$.getjson('statistics_get.php',function(output) {             $.plot($("#graph_1"), [{                         data: output,                         lines: {show:true}                         }]                     ); }); 

now, using firebug, response of form:

{"0":"0","1296658458000":"566","1296725534000":"789","1297072385000":"890","1297072388000":"435"} 

flot not processing data. believe flot needs in form [[1,2],[4,5],[6,9]] etc. question is, best way of getting json array correct form flot read , produce graph.

don't use array_combine, since doesn't need. doing "zip" in php little bit unpleasant, should able manage with:

function make_pair($date, $amount) {     return array($date, $amount); }  $data = array_map('make_pair', $date_dispatched, $amount); 

and json-encode that.
