-1- not right now
-2- not in a CDEF, but in a VDEF

In theory it should be possible to get this data from the RRD.
It has not yet been programmed though but VDEF was implemented
with this kind of requests in mind.

It won't be easy, not just a matter of a couple of lines of code.
IIRC the graph functions have no direct access to the relevant
portion of the RRD.

I have not continued development of VDEF due to time shortage.
Food has priority over fun, I'm sure you understand.  Perhaps
I pick things up Real Soon Now[tm] but I cannot promise that I
will.  Maybe someone else is willing to implement this, and
similar, features right now.
