Thanks Alex!
Just in case someone happens to run against this same issue - I've found
that I can achieve what I'm looking for by doing my calculations in a CDEF
first, then using the series in a VDEF. So for the example below (my
actual situation is slightly different), it'd be something like:
CDEF:ds0_bits=ds0,8,*
VDEF:ds0avg=ds0_bits,AVERAGE
I'm not sure that it can be safely said that _any_ calculation can be
reworked this way, but it's an option.
