javascript - Highcharts: Format all numbers with comma?

I'm using Highcharts and I want to format all numbers showed anywhere in the chart (tooltips, axis labels...) with comma-separated thousands.

Otherwise, the default tooltips and labels are great, and i want to keep them exactly the same.

For example, in this chart, the number should be 2,581,326.31 but otherwise exactly the same.

enter image description here

How can I do this?

I tried adding:

    tooltip: {
        pointFormat: "{point.y:,.0f}"
    }

But this got rid of the nice circle and series label in the tooltip - I'd like to keep that. And ideally I'd prefer to use a single option to set global number formatting, across the whole chart.

This can be set with the thousandSep (API) global option.

Highcharts.setOptions({
    lang: {
        thousandsSep: ','
    }
});

See this JSFiddle example.
