Hey @aadavis2890 ,

i have some points as solutions. I have not used the charts till now.

  1. in your database if have given ‘Currency’ as data type to WeeklySales then i don’t think it will need to be formatted here.
  2. chack the ‘Customise tooltip number formating’, you will get the bellow options

    try it.
    I Hope this will help you.

Just let me know what are the results.
