So what does the direction of plotting have to do with that?

If you want to plot data that's different from the actual one you pulled 
out of your database, what keeps you from doing so in the program that 
sits between the DB and gnuplot?

That sounds like you might be talking about a monotonically falling 
smallest upper bound of the actual data, but I'm afraid you lost me 
halfway along that sentence.

I guess you meant "horizontal line" there.

Frankly?  No.
