HISTory:CURRent[:HISTogram]?
<supply> returns the histogram data held for the
specified <supply>. Ten values are returned for the amount of time the <supply>’s
current spent in ten different current ranges. Those current ranges can be queried
with the MIN and MAX optional parameter. The units of the time values returned
are HOURs by default, but can be changed with the
HISTory:UNIT[:TIME]
command.
The units returned for current ranges queried with the MIN or MAX parameters are
integer values in milliamps.

returns 10 values representing the maximum currents in
each current range in milliamps.
