I would like to plot a spectrum (output of FFT) with a form like the provided image. How do I do it? Because the common plot in matlab is connecting of all point.

Use the stem (link) function for the plot.
Example
f = 0:0.1:3.5; % Create Frequency Vector
h = exp(-f) + 0.5*rand(size(f)); % Create Amplitude Vector
figure
stem(f, h, 'Marker','none')
