FWIW, I adopted a different hack, splitting the arrow (which is really a 
‘yzeroaxis’ in my plot) in two:

set lab "|b|² ~ 1/4" at -2.2,4.5 tc ls 3 noenh
set obj rect center 0,4.5 size char 1,char 1 fs solid noborder front
set arr from 0, graph 0 to 0, graph 0.3 nohead front
set arr from 0, graph 0 to 0, graph 1   nohead

Though this may be less general as a solution.

Nice.  That is what I was looking for :-).
