Apologies if this has been asked before:

I need to create my chart data in a servlet and then pass using AJAX. This is all working fine but I can't understand how to pass a datetime without having to reprocess it in JavaScript.

I have tried passing millseconds and also strings of the format: 2016-08-08T02:17:14.315Z but these dont appear to be seen as dates

my code is below: any help would be appreciated please

Code:

$('#jqChart').jqChart({
               title : 'Web Service 1',
               tooltips : {
                  type : 'shared'
               },
               legend : {
                  visible : false
               },
               axes : [ {
                  type : 'dateTime',
                  location : 'bottom',
                  zoomEnabled : true
               }, {
                  type : 'linear',
                  location : 'left'
               } ],
               series : [

               {
                  type : 'column',
                  title : '##',
                  data : concurrent_transactions_data.chartdata
               }

               ]
            });


and ideally I would like my JSON to be using millisecos like this:

Code:

[["1470567194319",259],["1470580154318",243],["1470593114317",252],["1470606074316",263],["1470619034315",265],["1470631994314",272],["1470644954313",249],["1470657914312",263],["1470670874311",259],["1470683834310",269],["1470696794309",256],["1470709754308",265],["1470722714307",267],["1470735674306",273],["1470748634305",243],["1470761594304",270],["1470774554303",255],["1470787514302",259],["1470800474301",254],["1470813434300",253]]

Hi,

in your case your data can be in the following format:
Code:
[[new Date(1470567194319), 259], [new Date(1470580154318), 243], [new Date(1470593114317), 252], ...]


You can also check this example:
