highcharts - Navigator showing at 1970 when first point is null -


i've got data being loaded asynchronously client. time time, null time , value pairs received. if happens, navigator shows beginning @ 1970. i've tried setting initial point first timestamp in navigator series , problem persists, null in series being displayed.

is there solution can suggest or workaround?

here's code , a fiddle:

$(function() {     $('#container').highcharts('stockchart', {          chart: {         },          navigator: {             adapttoupdateddata: false,             series: {                 name: 'navigator'             }         },          rangeselector: {             enabled: false         },         series: [{             name: "billy"         }         ]     });      var data = [[null, null],                     [date.utc(1990,  9, 27), 10 ],                     [date.utc(1990, 10, 10), 20 ],                     [date.utc(1990, 10, 18), 30 ],                     [date.utc(1990, 11,  2), 40 ],                     [date.utc(1990, 11,  9), 50 ],                     [date.utc(1990, 11, 16), 60 ],                     [date.utc(1990, 11, 28), 50],                     [date.utc(1991,  0,  1), 40],                     [date.utc(1991,  0,  8), 30],                     [date.utc(1991,  0, 12), 20],                     [date.utc(1991,  0, 27), 10]]     var chart = $('#container').highcharts();     chart.series[0].setdata(data);     chart.xaxis[0].setextremes(chart.xaxis[0].min, chart.xaxis[0].max, true); });

you can't have null x value in highcharts.

if have no y data point, specify data (ie) [date.utc(1990, 9, 27), null]

a null x , null y gives nothing meaningful, don't know when null value (ie, problem) occurred.
