Fluke 8588A Operator's Manual page 95

If  (Plot) is selected to Histogram,
 (Bin Settings) provides control of the horizontal axis, using either Auto or
Manual. As long as new readings are being made, changing between Auto and
Manual gives different views of the reading distribution. If the data collection is
stopped by a push of , only the present view of the data shows. For
example, if Bin Settings is set to Manual, after you push , only the
Manual bin view shows.
