How to write two variables on the x-axis and change corresponding Xlimits?

how to put two xtick labels in a plot. I have CC versus AA plot. I would like to write the corresponding values of BB on X-axis along with AA-coordinates. Is it possible? The code may be like:

load('AA.mat');
load('BB.mat');
load('CC.mat');
plot(AA,CC);

The example data is attached below.

Is it also possible to Change the values of BB scale in response to the change in X-limit? Any help will be greatly appriciated. Thank you so much.

The figure appears like this:

Thanks for your reply. But, I would like to add that my actual data is something like CC = 31189x17 matrix.

I use pcolor to plot my first plot, and would like to add another scale to this pcolor plot.
