feature that allows you to view a
large amount of time data in the
ByTime Graph view. A scale
factor of 1 to 1024 can be
selected. A scale factor of greater
then 1 will cause multiple pieces
of time data to be graphed to 1

will not move to the next graph

be displayed for each graph
cursor point and allows the user
to observe an overall shape of the
measured data on screen without
the need for scrolling.
