Can you also share the source of these files

If I remember correctly, the columns 2 and 4 are the values of change in distances (cm). We used a linear actuator to simulate a human breathing pattern and used a doppler radar to acquire those data. We directly acquired the files from the data acquisition device.

To calculate and plot the continuous wavelet transform of your signal, use the cwt (link) function.
Specifically:
Mn = dlmread('Normal_Breathing.txt', '\t', 2, 0);
Fs = 100;
figure
cwt(Mn(:,2), Fs) % Continuous Wavelet Transform Of ‘Column 2’
Since this is your research, I leave the rest to you.
