Transform Axis

Hello,

I am trying to work with the "Transform Axis" in IgorPro6.03A version.

My bottom axis is in eV, I would like to have a top-axis in nm.

Somehow (even after reading "HELP" topic) I just do not manage to make it work - probably I fail to understand how to proceed (sorry!)

So I did the following:

1) Created a "coefficient" curve according to the following logic: nm_wave=CoeffCurve_wave/ev_wave

2)The CoeffCurve_wave consists of a single number: 1239.8 [units of "nm*ev"] (the length of CoeffCurve_wave is however the same length as ev_wave).

3) Now I go to "Transform Axis" package, choose "reciprocal" and choose the coefficient wave Coeff_Curve_wave. And it does not result in nm! Seems that is simply gives the "Reciprocal" (1/ev_wave) on my top-axis! (I understand that reciprocal is 1/bottom axis...)

How to make the bottom axis in eV and the top axis in nm?

Thank you in advance.
OK, it worked, after using "Modified reciprocal" and the coefficient wave consisting of two values: w[0]=1239.8 and w[1]=0. Then it seems to calculate: f(x) = w[0]/(x+w[1]). Nice :)
