Hi,
To expand on @Mark_Bailey post, you can retrieve the formula from any column by using the following script:
Names Default to Here (1);
dt = current data table ();
form = char (column (dt, "YOUR_COLUMN")<< Get Formula);
show (form);
However, you will need to use another script to add the retrieve formula to each frame on your GB plot.
Best,
