Detailed Description

Accumulated statistics for all frames falling within a single I/O graph time interval.

Note

frames and bytes are always computed regardless of the active io_graph_item_unit_t. The min/max union members use 64-bit integers rather than doubles so that the originating frame number can be tracked exactly; values are only converted to double at plot time. Totals use double to avoid overflow across large intervals.
