编辑： Ductho Le 2021-1-14

I have a set of points and their amplitudes. I want to plot a graph like this (fig bellow) in which amplitudes are plotted as the spectra of every points.

I plot the graph with command:

plot(f,pv,'k.') % f: frequency; pv: phase velocity

Could you help me to impose amplitude to this plot.

Thanks in advance.
