logaritmic histogram

Hallo,

I have (another) simple question. How can I make logaritmic histogram?
If I use ( X is an array of input data ):

    from pylab import *
    logX = log10( X )
    n, bins, patches = hist( logX, 50 )
    show()

I must take a special care for x-axis labels. Is possible to use
semilogx()? How?
