javascript - Chart.js number format

Question

I went over the Chart.js documentation and did not find anything on number formatting ie) 1,000.02 from number format "#,###.00"

I also did some basic tests and it seems charts do not accept non-numeric text for its values

Has anyone found a way to get values formatted to have thousands separator and a fixed number of decimal places? I would like to have the axis values and values in the chart formatted.

Put tooltips in 'option' like this:

options: {
  tooltips: {
      callbacks: {
          label: function(tooltipItem, data) {
              return tooltipItem.yLabel.toFixed(2).replace(/d(?=(d{3})+.)/g, '$&,');
          }
      }
  }
}
