i have problem because used googlechart , chart can't read format of json. format of json isn't good, it's

" new date(2012,11,17) "   

but need

" date(2012,11,17) " 

could me ?

i don't know api, need build date object , convert date string before sending json object.

try

var date1 = new date(2012,11,17).tojson(); ... google.visualization.query.setresponse({...,{"v": date1}...});
