Can you explain how it's not working for you? The Group By option will cause the Fit commands to perform one fit for each level of the grouping variable.

I used your data table and and ran Fit Y by X with myX and myY respectively.

Then I chose the "Group By..." option from the Bivariate menu and used Name as the Grouping variable.

Then fit a line and got this result:

First, welcome to the community.

Use the Group by when running the platform Fit Y by X. I have added the script to your data table.
