Interface TransposeRowOptions

Which row to read across. Default 'last' — the head / latest row (the live snapshot). 'first', an index (negative from the end), or { time } for the row nearest a key.

The columns to lay on the axis, in order — a declared / bounded set (a watchlist, or a top-N computed upstream; the RFC §7 "bound in the data layer" stance). Omit to use every numeric value column of the series, in schema order. A named column that's missing / non-numeric in the row reads as a gap.
