Hello everyone,

My problem is that I want to obtain a graph similar to this one (consider the green bars only) with Matlab.

The things is that with a logarithmic absciss scale with Matlab, I obtain:

Is there a way to generate bars with a width that increase when this bar is located on the right of the absciss scale in order to hev "visualy" the same width for each bar ?

Regards

N.B : I put my code as an attached file but it is quite simple.

Instead of making the x-scale logarithmic by set(gca, 'xscale','log'), use linear x-scale and log10(Frequency) as X

I used the stairs plot function with specified band edges. Code is attached.

What I don't know is why the fractional spectra from poctave would be different, depending on whether I calculate them from time signal os the time signal's PSD. If anyone has an idea, please help.
