Origin Version (6.1): Operating System: Win XP Hi I want to add anew X axiss in the top. My X axiss is in eV and i want to add an axiss in nm. Please helpe me. Yahya
go to 'Edit' --> New Layer(axes) --> (Linked): Top X Then you can click top X axis and change scale into whatever you like it. It will not interfere with bottom axis. I hope it is what you want.
