The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Graph all objects in a table, which is located above all the individual graph icons. |

Graphs show properties over time, enabling you to determine when significant events occur. For example, you can graph traffic to identify unexpected shifts, visualize growth trends, and determine whether traffic returns to normal levels after maintenance. Drops in traffic could indicate a routing problem. Figure 3-1 shows an example of a single Explore graph of an interface’s Traffic In and Traffic Out over the last week.
Note that these graphs are available both through the Explore pages and as part of the output generated by most reports.

Measurement gaps can occur when objects appear and withdraw from a network, when circuits become operational and non-operational, or when demands appear or disappear due to traffic fluctuations. While these are normal conditions, you might find the data easier to read if you adjust the Data Gap value.
Reports include an aggregate measure, for example P95 over one day. When measurement gaps span the aggregation period, the graphs keep the aggregate at a constant rate using the last aggregate calculation. The result is a continuation of a graphed line when possibly there is no data due to network maintenance or failures. You can show these gaps by adjusting the Data Gap value.
– One property across multiple objects in either an overlay or a stacked manner.
You can graph all objects by clicking the Graph All icon at the top of the table. Thereafter, there are three available graph modes.
Individually graphing each property per object is useful when you want to see all of the data for an object in one place. For example, this mode makes it easy to compare inbound and outbound traffic for a particular interface. Figure 3-2 is an example where the Traffic property for three LSPs is graphed using the Individual Object graph mode.
Figure 3-2 Example of Graphing Individual Objects
You can graph a single property for multiple objects either by overlaying them or by stacking them. Figure 3-3 shows an example of each using the same data (Traffic property, time frame, and LSPs) as was generated for Figure 3-2.
Figure 3-3 Example of Overlay and Stack Graphs
WAE Live assigns each object an object ID and graph color, and lists this association below each graph, thus identifying which data belongs to which object (Figure 3-4). As you move your cursor over the data points, the sum of the property values is listed along with the value of each object. To open or close the Object Reference section, click its arrow.
