<div id="container" style="height: 400px"></div>

var chart = new Highcharts.Chart({

Answer 2

I developed a Jalali Date library, JDate, that is compatible with original javascript Date class. Dates in highchart/highstock charts can be converted to Jalali by replacing window.Date with JDate. With this method all date outputs is converted to jalali calendar, And also, date input features (like YTD feature, or range selector) works with jalali calendar.

Demo: https://tahajahangir.github.io/jdate/jalali-highcharts-demo.html

The main part of script in above demo, is:

<script src="//raw.githack.com/tahajahangir/jdate/master/jdate.min.js"></script>
<script>
    window.Date = JDate;
    Highcharts.setOptions({
        lang: {
            months: ['فروردين', 'ارديبهشت', 'خرداد', 'تیر', 'مرداد', 'شهریور', 'مهر', 'آبان', 'آذر', 'دی', 'بهمن', 'اسفند'],
            shortMonths: ['فروردين', 'ارديبهشت', 'خرداد', 'تیر', 'مرداد', 'شهریور', 'مهر', 'آبان', 'آذر', 'دی', 'بهمن', 'اسفند'],
            weekdays: ["یکشنبه", "دوشنبه", "سه شنبه", "چهارشنبه", "پنج‌شنبه", "جمعه", "شنبه"]
        }
    });
</script>

I borrowed this js script and tried it out here. Not sure if that is what you are after though.

You can use it babakhani persian date js for example:

---

xAxis: {
                    type: 'datetime',
                    labels: {
                        formatter: function () {
                            var date = new Date(this.value);
                            var pdate = persianDate(date);
                            return (pdate.pDate.year - 1300) + "/" + pdate.pDate.month;
                        }
                    }
                }

Answer 5

Then better way to override date formating is to use Highcharts.dateFormats (and persianDate library), This allows conversion of all dates (not x or y axis) to Persian calendar.

Sample: http://jsfiddle.net/smpaB/1/

Add pesianDate library with:

<script src="http://rawgithub.com/babakhani/PersianDate/master/dist/persian-date.min.js"></script>

And configure highcharts with:

Highcharts.dateFormats = {
    'a': function(ts){return new persianDate(ts).format('ffffdd')},
    'A': function(ts){return new persianDate(ts).format('ffffdd')},
    'd': function(ts){return new persianDate(ts).format('DD')},
    'e': function(ts){return new persianDate(ts).format('D')},
    'b': function(ts){return new persianDate(ts).format('MMMM')},
    'B': function(ts){return new persianDate(ts).format('MMMM')},
    'm': function(ts){return new persianDate(ts).format('MM')},
    'y': function(ts){return new persianDate(ts).format('YY')},
    'Y': function(ts){return new persianDate(ts).format('YYYY')},
    'W': function(ts){return new persianDate(ts).format('ww')}
};
