How to change time in hours on HighChart xAxis from Military to Standard time?

Question

http://jsfiddle.net/leongaban/gbqvv0y9/

I've tried to edit the dateTimeLabelFormats key to have the chart use the much more readable Standard time, however no results...

$(function () {
    $('#container').highcharts({
        chart: {
            type: 'spline'
        },
        title: {
            text: 'Wind speed during two days'
        },
        subtitle: {
            text: 'May 31 and and June 1, 2015 at two locations in Vik i Sogn, Norway'
        },
        xAxis:[{
            dateTimeLabelFormats: {
                hour: '%H:%M'
            },
            type: 'datetime',
            labels: {
                overflow: 'justify'
            }
        }],
        yAxis: {

Answer 1

Change hour: '%H:%M' to hour: '%I:%M %P' . Here is the updated fiddle .

For more formats refer - http://php.net/manual/en/function.strftime.php

Answer 2

Just figured it out! How to get highcharts dates in the x axis?

dateTimeLabelFormats: {
    hour: '%I:%p'
}

Update! This is the new way to swap Military time to Standard time:

dateTimeLabelFormats : {
    hour: '%I %p',
    minute: '%I:%M %p'
}
