# sampling rate transform math:
# -----------------------------
# define the fast chart to slow chart as a linear mapping
# over the fast index domain `i` to the slow index domain
# `j` as:
#
# j = i - i_offset
# ------------ + j_offset
# j/i
#
# conversely the inverse function is:
#
# i = j/i * (j - j_offset) + i_offset
#
# Where `j_offset` is our ``izero_hist`` and `i_offset` is our
# `izero_rt`, the ``ShmArray`` offsets which correspond to the
# indexes in each array where the "current" time is indexed at init.
# AKA the index where new data is "appended to" and historical data
# if "prepended from".
#
# more practically (and by default) `i` is normally an index
# into 1s samples and `j` is an index into 60s samples (aka 1m).
# in the below handlers ``ratio`` is the `j/i` and ``mn``/``mx``
# are the low and high index input from the source index domain.
