Format Data

As you can see in my attached observable notebook, I have a drop down menu with years in it. They are being interpreted as numbers and are including a comma. How can I go about removing that to just have a flat year.

The 4-digit year is a number, so is getting formatted with the thousands separator. I would cast the index to a string:

groupYears =, (d) => d.year.toString())

and then

viewof filter_date_select =
  { value: groupYears.get("2024"), sort: true, label: "MLB Season" }

Define the grouped data separately so that you can default the value to the “2024” data.

Thank you so much. That was a very helpful answer. Much appreciated!!
