I have here two data sets, one I want to use as my X and the other the Y axis.
For the X, which is my TNF placeholder values below, I want to simply sort the data array from least to greatest. Which I already know how to do. The Y values, TPF, are also shown below and correlate specifically to the respective index of the TNF array.
TNF = [e, a, d, c, b]
TPF = [e, a, d, c, b]
Sorted, it looks like:
TNF = [a, b, c, d, e]
So how to I get the TPF values to sort with the TNF values and not independently from least to greatest?

Ise the second output of the sort function to return the indices, then use those to map ‘TPF’:
TNF = ['e', 'a', 'd', 'c', 'b']
TPF = ['e', 'a', 'd', 'c', 'b']
[TNFsorted, idx] = sort(TNF);
TPFsorted = TPF(idx)
