How to make a stairs + semilogx plot?

I have a spectrum of sound pressure measurement in one-third octave band starting from 25 Hz to 4000 Hz. I would like to make a staircase plot with x axis in log scale, i.e. a stairs + semilogx plot. Each stair should extend from the lower cutoff and higher cutoff frequencies of each band. How to do it?

I don't know if this is what you want, but here is a quick example to combine stair plot with log scale in x

stairs(1:10,1:10);
set(gca,'XScale','log');
