Highcharts: Format all numbers with comma?

Question

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

Answer 1

This way worked with me.

I configured in yAxis option.

yAxis: {
  labels: {
    formatter: function() {
        return Highcharts.numberFormat(this.value, 2);
    }
  }
}

Answer 2

In case you want to show numbers without commas and spaces.

eg. by default 9800 shows as 9 800.

If you want 9800 to be shown as 9800

you can try this in tooltip:

    tooltip: {
     pointFormat: '<span>{point.y:.f}</span>'
   }

Answer 3

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

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

See this JSFiddle example.
