and not able out put , getting json data using different file , getting json data using ajax code in code ... there other way solve issue.

you don't seem getting because $.ajax asynchronous, meaning when call it, starts request, , continues next statement (before data returned)

if goes well, end in method assigned success. should drawing chart.

google.load("visualization", "1", {packages:["corechart"]});  function drawchart() {     $.ajax({         url:'getdata.php',         type:'get',         datatype:'json',         contenttype: 'application/x-www-form-urlencoded',         async:false,         success: function(data){             var options = {                 title: 'my daily activities',                 piehole: 0.6,             };             var chart = new google.visualization.piechart(document.getelementbyid('piechart'));             var dataasdatatable = google.visualization.arraytodatatable(data);             chart.draw(dataasdatatable, options);         }     });     }   //typically idea define functions or variables *before* //passing them reference. not quite sure code below do, //but since references drawchart function, should executed after //defining drawchart.  google.setonloadcallback(drawchart);

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
