Khalid, what you can do is to note how
much the higher energy (at energy E1) feature is shifted from what you think it
should be (let’s say by the amount of D eV), provided that you fixed the
lower energy point to what you wanted (say, E0). Then, you should transfer the
data into a spreadsheet and apply linear scaling:
It will ensure that in the range between
E0 and E1 the data are linearly stretched or compressed, depending on the sign
of D.

Is it
possible in Athena to change the y-axis (energy
scale) at two different energy points of an EXAFS scan?
I have a Ni foil spectrum as a function of time.
The edge can be set at 8333.0 eV, and I want to
to assign higher energy to a known feature in the Ni scan.
