Hello,

I have a problem that I've been trying to solve for a while. I have a line-plot with wavelength on the bottom x-axis. I want to create a second layer in which I will have corresponding energy on top. I know how to do this manually from the 'plot-details' menu (see screenshot), but how to do this in code? I tried as described below, but when I zoom in one layer, the other does not rescale. 


double start_eV = X1;
double stop_eV = X2;

double start_nm = 1240/start_eV;
double stop_nm = 1240/stop_eV;

layer -n X;

X1 = start_nm;
X2 = stop_nm;


This is what I want to achieve:


Origin Ver. 8.5.0
Operating System: Win 7

Hi,

The LabTalk script for setting custom formula for linking axis is only available since Origin 2015 SR0 by command:


layer.axis.link.from$;

layer.axis.link.to$;


There is no way to set it using LabTalk script in Origin 8.5, you can find its reference in this page:

Regards!
