I am using
spectrogram(singal,[],[],[],Fs,'yaxis');colorbar;
command and I would like to normalize the power values obtained in the colorbar. However, I have not seen any way in the documentation to do it. Any suggestions?

There doesn't seem to be a direct way to normalize the output of the Spectrogram figure. However, you can workaround this by using [~,ps] = spectrogram(singal,[],[],[],Fs,'yaxis'); to extract out the power density values to MATLAB and then normalize the values manually depending on your use-case.
