One would follow the stackplot call with calls to xscale('log') and/or 
yscale('log').  This works fine for the x-axis (if x values are 
positive), but when the y-axis is log, the bottom region is not filled, 
presumably because it is trying to fill down to zero.  I haven't looked 
at the code, so I don't know whether there is some way of improving this 
behavior without the stackplot call knowing beforehand that it will be 
dealing with a log axis.
