Hi Simon,

Interesting. I guess there is an issue with the sort of coordinates 
being passed to the special rendering. I have a feeling that it maybe 
defines the coords as fractions of the main plot, so if the main plot 
has zero height then the specials are also squeezed to zero height. Just 
a guess. Not sure what the workaround is, other than hacking the .tex 
file output by rivet-cmphistos...

It'd be good to improve this, but far down our priority list as you can 
probably guess. Could you maybe take a look at the make-plots code and 
see if there'd be a better/alternative way to embed specials or give 
them coordinates relative to the whole plot frame/canvas? It feels like 
that's what's needed. Maybe with a control flag to choose what the 
default special coords are relative to.

Andy
