In this case all the values were naturally in [0,1], so the reference
line was obvious once I'd seen the plot. In general, tho, there is no
standard procedure. You need both some idea of how the curves might
differ and a "sense of the data" to know what rescalings may be
permissible. It's an art, not a science.
