This window appears when you choose Reports > Bandwidth Graphs from the menu bar (or when you right-click a switch and select Bandwidth Graph from the popup menu). You can also click here to launch it. Use it to:
From the Type list, click Line, Bar, or Area to select a type of graph. The appearance of each type is described in this table.
Graph Type | Appearance |
Line | Data points are connected by a line. |
Bar | Data points are denoted by the height of bars. |
Area | Data points are connected by a line, and the area under the line is filled in. |
By default, the time increments on the x-axis are 15 minutes apart. To make them closer together or farther apart, select a different value from the Increments list.
If you check the Define Time Span box, you can define the x-axis by holding down the left mouse button and dragging along a segment of the axis. The segment you choose expands to become the entire x-axis. By right-clicking the graph, you return to the default x-axis.
Note: You cannot use the Increments list if the Define Time Span box is checked.
Check the Log Scaling box if you want the increments on the y-axis to scale upward logarithmically rather than arithmetically.
The scroll bar at the bottom of the graph lets you scroll left and review past data points that have moved off the graph. You can then scroll right to return to the most recent data.
Note: The graph is updated each time the switch is polled. You can change the polling interval (the frequency for collecting the data) by selecting CMS > Preferences and using the Preferences window.
