legend('100\Omega','1k\Omega','100k\Omega', '10M\Omega')

xlabel('Excitation frequency (Hz)')

ylabel('|Power FRF| [\muW/g^2]')

Read about findpeaks. This does exactly what you want.

If you copy my data and the rest of the program , you will obtain the curve.

But, i want to display every frequency of the peak in the x axis.

Please help me
