Highchart - Set Time(Hour:Minute) on X axis - highcharts

Question

I did not able to get labels like [12:00,12:15,12:30,12:45,01:00,01:15,..] on X axis.
I got only 00:00 on X axis.I was not able to display increasing time values on X axes.
I want to start default from 12:00.
I used following code.
xAxis: {
type: 'datetime',
tickInterval : 1.5 * 3600 * 1000,
dateTimeLabelFormats : {
day : '%H:%M'
}
}

Answer 1

This worked for me in Dynamic Highchart.
$(document).ready(function () {
chart = new Highcharts.Chart({
chart: {
renderTo: 'container',
defaultSeriesType: 'spline',
events: {
load: requestData
}
},
title: {
text: 'Sensor Data Vs. Time'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150,
maxZoom: 20 * 1000
},
yAxis: {
minPadding: 0.2,
maxPadding: 0.2,
title: {
text: 'Value',
margin: 80
}
},
series: [{
name: 'Sensor Data',
data: []
}]
});
});
With this I am displaying Hours, Minutes and seconds as well.

You haven't shown us what data you are supplying. Something like this works:
series: [{
name: 'Temperatures',
pointStart: new Date().getTime(),
pointInterval: 24 * 3600 * 1000,
data: [1.5 * 60 * 1000,1.2 * 60 * 1000,2.5 * 60 * 1000,1.9 * 60 * 1000,],
}]
