Specifying a Graph Format
The Bar drop-down menu, located in the upper right-hand corner of a graph, is
used to change the appearance of a graph. You can display plots on a graph as a
Line, Bar, or Stack.
Click on the drop-down menu to change to any format listed in the following table.
Graph Format
Description
Line
Displays a linear graph of data as connected points.
Bar
Plots each data set value at each point as a bar of a different color.
Stack
Places the data set bars on top of each other. This is similar to
creating a bar graph.
A Pie graph is also displayed for Frame Relay and DSL interfaces, but it is not
user selectable. A Pie graph displays a total bandwidth or utilization for each
access point across data sets and each set is shown as a slice of pie. This is
equal to four ports on a DSL card or the utilization of all DLCIs configured for a
Frame Relay link.
Querying a Point on a Graph
To obtain the exact timestamp and value of a graph point, you must query this
point.
"
Procedure
To query a graph point:
1. Position the cursor over a point on the graph.
2. Press the right mouse button. The exact time and value of the point closest to
where you clicked is displayed in the pop-up menu.
If you perform the previous steps on a Pie graph, menu items that provide quick
navigation to other chart types are also displayed. Clicking on an Unused portion
of a Pie graph renders no information.
