I'm unfamiliar with "P-n-L management" and not too sure what you want to
graph. Whatever you graph it has to be numbers currently in the sheet. It
cannot be a history of numbers that have been in a given cell over time. So
you'd want to build a history down a column or across a row.

As to calculating the greater of two numbers, the conventional way is
=IF(A1A2,A1,A2) or better =MAX(A1,A2). You can do a range of numbers like
this =MAX(A1:A100) or =MAX(A:A) for all of column A.
