stored than will fit on the screen.
Individual subgroups are selected by a vertical line on the graph. Move
the vertical line left and right through the stored data using the arrow
cursor keys. The time and date when the selected subgroup data was
stored are shown in the upper left corner of the screen. The ID number
of the subgroup and the value of the data for the dimension are also
