Time Series chart xtrace font

I am trying to learn how to add a comma every 3rd digit to my axis
I don’t know how to pull out the right thing.

maybe it is : class="yaxis ia_timeSeriesChartComponent__yAxis__values ia_yAxis"

I don’t really know. Then I also don’t know how to set the comma.
I went to the w3 css reference and searched for comma, but no results.
Searched format, no results.
font-variant-numeric seemed like the best from a search of number

`class=“yaxis ia_timeSeriesChartComponent__yAxis__values ia_yAxis” fill=“none” font-size=“10” font-

class=“ia_timeSeriesChartComponent__yAxis__ticks”
class=“ia_timeSeriesChartComponent__yAxis__axis” x1=“0” y1=“0” x2=“0” y2=“498”>`

It was a feature request 2 years ago, but I don’t see it in 8.1.0 which I am using.
