The legend displays the current reads and writes per second in bits, as well as the total amount read/written.
The y-axis automatically scales based on shown read/write values, and by default, is a linear scale based on base-10 units (e.x. kilobit, gigabit, etc.).
Through [configuration](../../../configuration/command-line-flags/), the read/write per second unit can be changed to bytes, while the y-axis can be changed to a
log scale and/or use base-2 units (e.x. kibibit, gibibit, etc.).
