Hi,
I need to deduct 2 graohs from each other in excel. The sets of data used to
create the graph have different x values so I can't just deduct them from
each other and because they have been collected from a research project they
have no regularity to create a function or trendline. Is there anyway to
create this at all?
ther are more than a thousand values so this can't be done by hand.
Any help would be appreciated
