whether to wrap the buffer when the maximum 3,600 samples have
been collected. First select the sample you want to use from the History

You can use the Zoom In\Zoom Out context menu options to narrow
or broaden the focus of a history sample while it is collecting data. These
options change the range of data points displayed, allowing you to focus
on a specific small time period, or, alternatively, see broad trends over
a comparatively long duration.
You use the Zoom In\Zoom Out feature by right-clicking anywhere in
a History Sample’s graphical display and selecting the desired option
from the context menu that appears. Figure 5-12 shows a Packets/s
History Sample with the context menu displayed.
NOTE: The Zoom In\Zoom Out feature has three levels of detail.
If you are already zoomed to the narrowest view, the Zoom In
command will be grayed out in the context menu. The reverse is
true of the Zoom Out command.
