Because you want the limits to be scaled to the same axis as the data,
I'd stick with alarm lines, or two plots filling one to the other. The
only downside of this is that i
t puts the limits in the legend. The
only bad thing about this is that the user might be able to change
colors or thickness of the limits, which is also not a bad thing if they
have trouble seeing the colors you selected.
