Zooming History Graphs

History graphs display measurement history in intervals. Each
interval is represented by a bar on the history graph. The interval of
time represented by a bar can be changed. Changing the interval a
bar represents is called zooming. History graphs can be zoomed out
or in. When a history graph is zoomed out, a bar represents a
increasingly longer period of time. When a history graph is zoomed
in, a bar represents a decreasingly shorter period of time. Table 3–35
lists the intervals a bar can represent, depending on the history
resolution setting when the test was run.
