Formatting datalabels

[Samamoah]

Hello I want to add commas to my chart labels. Like from 56789 to 56,789. I am using version 2.9.4 of Chart.js and version 0.7.0 of of the label plugin. Tried the formatter didn't work

@Samamoah I was able to get this to work using chartjs 3.0 and a regex. I know you're using 2x, but if you happen to upgrade this should do it. I never got it to work using toLocaleString which would have been much cleaner.

datalabels: {
  formatter: (value, ctx) => {
    return value.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ',');
  },
}
