How do I normalize multiple curves using JMP?

I have an XPS data with multiple curves based on different conditions. I want to normalize so that it can be compared. Attaching image as an example. Can something like be done using JMP?

JMP version 16.0

Hi @Harigovind : Perhaps this: For each X, try the following,

(:X - Col Mean( :X )) / Col Std Dev( :X ) + Col Mean( :X )

This will result in each having a common spread (SD =1), but the means will be shifted apart as your plot shows.

In a column formula, it would look like the following:

Further...say you want them all to have the same spread (SD) as one of them. For example, if I have X1 and X2, and I want to shift and scale X2 so it has the same SD as X1, but a different mean (as you want to show). Leave X1 as it is, then shift and scale X2 as follows:

You might try the built-in transforms in the Functional Data Explorer if you have JMP Pro.
