Add a semilogx axis to a plot given by a function

I am using the function obw() to plot occupied bandwidth with the code:

obw(signal, fs);

It plot it on a normal frequency linar scale and I would like to plot it with a log x-axis (like when you use the function semilogx(). How can I do this? Thanks heaps!

set(gca,'XScale', 'log')

Thank you very much Walter! It worked. I wanted to add minor ticks and so did:

 set(gca,'XMinorTick','on')

But that doesn't work. Any hints why?

EDIT: I found out that this problem disappear when I remove the change of font size that I had set up... not sure why but I don't mind!
