please me in project. thankyou

you need update data in chart, example:

$(document).ready(function() {     var options = {         chart: {             renderto: 'container',             plotbackgroundcolor: null,             plotborderwidth: null,             plotshadow: false,             // add code below:             events: {                 load: function() {                      var series = this.series[0];                      settimeout(function() {                          $.getjson("data.php", function(json) {                              series.setdata(json);                          });                      }                 }             }         },         //rest of options , code     }; });
