javascript - HighCharts with Dynamic Data not working -

-

i have asp.net mvc project signalr.

i have page highchart , script looks this:

$(function () { window.highcharts.setoptions({     global: {         useutc: false     } });  var chart;  $(document).ready(function () {     chart = new highcharts.chart({         chart: {             renderto: 'container',             type: 'line',             marginright: 10         },         title: {             text: 'gmas queues'         },         xaxis: {             type: 'datetime',             tickinterval: 500,             labels: {                 enabled: false             }         },         yaxis: {             title: {                 text: 'queue count'             },             plotlines: [{                 value: 0,                 width: 1,                 color: '#808080'             }]         },         legend: {             enabled: false         },         exporting: {             enabled: false         },         series: [{             name: 'processing queues'         }]     });  });  $.connection.hub.logging = true; // reference auto-generated proxy hub.   var chartdata = $.connection.processingqueueshub; // create function hub can call display messages. chartdata.client.updatequeuecounts = function (data) {     //$.each(data, function(i, item) {     //    // add message page.      //    $('#chartdatalog').append('<li><strong>' + htmlencode(item.queuename)     //        + '</strong>: ' + htmlencode(item.length) + '</li>');     //});     // set updating of chart.     var series = chart.series[0];      $.each(data, function (i, item) {         if (item.queuename == "queue a") {             var x = date.parse(item.date),              y = item.length;              series.addpoint([x, y], true, false);         }     });   };

however, see graph not points.chart no points strange part series data points there: chrome shows data points

anyone know why highcharts not rendering points?

thanks, bill n

i have thank friend , co developer figuring out. smarter , braver man me. :) went highcharts source , found highcharts breaks if add graph series before initial animation completed. animation why clip-rect zero-width (it animates 0 full width on 1s when first create chart). end adding point series before animation starts. kills animation doesn’t fix width of clip-rect. fix add animation false series.

series: [{ name: 'processing queues', data: [], animation: false }]
