I would like to add a label including each set of peaks in the graphs below (4 labels per graph).

this was my code.

load 'HCl_DCl_Complete'
ds=table2array(HCl_DCl_Complete);
wn=ds(:,1);
Trans=ds(:,2);
Abs= -log10(Trans/100);
subplot(2,1,1);
plot (wn, Abs, 'r-');
xlabel('Wavenumber $$\tilde{\nu}  (cm^{-1})$$', 'Interpreter','latex')
ylabel('Absorbance')
title('In terms of Absorbance')
subplot(2,1,2);
plot (wn, Trans, 'k-');
xlabel('Wavenumber $$\tilde{\nu}  (cm^{-1})$$', 'Interpreter','latex')
ylabel('Transmittance')
title('In terms of Transmittance')
%those are the labels I would like to add.
txt={'Fundamental DCl', 'Fundamental HCl', '1st Overtone DCl', '1st Overtone HCl'};
%I have tried it with this interval but it did not work. 
text(wn(29120:end), Trans(29120:end), txt)
sgtitle('The IR spectrum of HCl and DCl')
