You can select alternative values for the X and Y axes on the graph. For example, Latency, the default value for the Y axis in the scatter plot graph, is the difference in time between the first event in an interval and the second event. You can replace Latency with other values, such as Time Order, or specific fields in either event of the selected interval. Define the axis values by choosing from the lists in either the X axis or Y axis rows below the scatter plot graph. The values in those lists are:
Latency
Time Order
Event 1 - Specify the event field
Event 2 - Specify the event field
The data fields of the event become available for selection in the second list of the same row. This allows you to use a data value of a selected event as an axis of the graph.
