Hi,

I would like to quickly add a baseline trend to a graph without having to
write (exemple: Value 30) the same number of time as of my X axis data.

Actually, I have to "emulate" a false line.

Is there a way to enter only one number and it automatically add the
baseline trend so we can see variance easily.

Thanks!
