How to plot a complex power spectrum using MATLAB?

I have all the |C_n|^2 and need to plot bars which represent the energy at intervals of w (angular frequency).
I guess this would be a bar graph but I want lines instead (which I can label if possible).
Something like this but only need labels for the x axis:

This might have what you are looking for https://www.mathworks.com/help/matlab/ref/fft.html
You could transform the data from output space (voltage vs time or similar) into a frequency spectrum (power vs frequency or similar) and then plot that.
