Select this to determine whether the display for a device or port group will include all ports, or
only the top N ports (where N is initially fifteen). Click the icon to toggle between the red X, which
indicates the top N limitation is not in effect, and a green check, which indicates that the top N
ports are being displayed. The top N ports are displayed in order from highest (largest percent
utilization or largest total errors) to lowest. The number of ports (N) is a user-configurable setting.
This option is available only for multi-port displays.
Select this to display the data as a line graph. This chart type is especially useful when displaying
individual errors for a single port.
Select this to display the data as a pie chart. This chart type is available only when you are
displaying statistics for multiple ports on a device, device slot, or in a port group. The maximum
number of slices in the pie is a user-configurable setting. It is initially set to display 10 slices.
Select this to display the data as a bar chart. A 3D bar chart is the default for all chart displays.
The 3D setting is also a user-configurable option.

The 3D setting is also a user-configurable option.
Select this to display the data as a stacked bar chart. This chart type is only available when you
are displaying individual errors for a single port.
Select this to display the data as an area chart. This chart type by default displays in 3D. The 3D
setting is also a user-configurable option.
Select this to display the data as a table.
Select this to zoom in on (magnify) the size of the display. You can select this repeatedly to zoom
up to three times the screen size.
Select this to zoom out (shrink) the size of the display. You can select this repeatedly until the

Select this to display grid lines on the background of the chart.

the icon to toggle between continuous updates, and suspended updates.
Select this to take a “snapshot” of the graph or table view of the current real-time statistics data.
Select this to bring up the graph preferences pop-up window. You can change a variety of settings,
such as graph and data colors, the sampling interval, or the number of ports in a top N display.
