Quarter format for date in tooltips?

Hi RAC Foundation

Quarter is not a built-in parameter you can use, but it’s possible to build your custom date formatter using custom code

In custom code, add the following function:

Highcharts.dateFormats = {
    q: function (timestamp) {
        var date = new Date(timestamp),
        quarter = (Math.floor(date.getUTCMonth() / 3) + 1);
        console.log(quarter);
        return quarter;
    }
};

In the tooltip field, you can now use %q to refer to this function

Example:
{point.key:Q%q/%Y}

This will show something like this:

Hope this helps

Cheers,
