	"""
Script that plots three histograms of quantities x1, x2 and x3 
sharing the same X-axis.

Arguments:
- x1,x2,x3: arrays with data to be plotted
- xmin,xmax: lower and upper range of plotted values, will be used to set a consistent x-range for both histograms.
- x1leg, x2leg, x3leg: legends for each histogram	
- xlabel: self-explanatory.
- sharey: sharing the Y-axis among the histograms?
- fig: which plot window should I use?

Example:
x1=Lbol(AD), x2=Lbol(JD), x3=Lbol(EHF10)

>>> threehists(x1,x2,x3,38,44,'AD','JD','EHF10','$\log L_{\\rm bol}$ (erg s$^{-1}$)',sharey=True)
