The fact that high binding energy is plotted at the left and low at the right has to do with the fact that in reality you are not measuring the binding energy of the photoelectron but the kinetic energy and that goes in the opposite direction according to the general formula BE = hν - KE, with BE = binding energy, KE = kinetic energy.

Dear Dr.Theo Kloprogge
yes we are agreeing to your answer
But still...Is there any Scientific problem or issues, if we are plotting the XPS spectra from Lower BE to Higher BE???
Spectroscopists prefer to plot high BE at the left. Specialist spectroscopy journals will generally insist on it too, but I have seen many papers in journals that were plotted the other way around. Technically there is not a scientific problem with it. For me personally I am so used to see the high BE at the left that I know without reference where most BE of the main elements occur. Most instruments will show the spectra that way too when you acquire survey scans and high resolution scans. When I see a plot the other way around it takes me a bit of thinking to do the same in that plot
