Axis with predefined values

Hello,
I would like to draw a TGaxis but with predefined values for each thick.
Is it possible?
thanks!

I am not sure what you are looking for. Is that alpha-numeric labels ?
Do you have a small example macro ?

I would like to add a second axis in which the values does not depend from the values of the original axis but they are measured values of a certain quantity.
I hope the example attached can clarify what I would like to do

Thanks!
