standardizing x-axes in hist

I am trying to produce a series of histograms of related data, for which I want the ranges and scales of the x-axes to be the same. However, I dont see an obvious way of doing this with hist, since specifying nbins will not guarantee the same axis for each. Is there some sort of hack that I can use to do this (or an argument I am overlooking?).
