You can analyze the file usage for one or more Transaction IDs and display the output as a pie chart, a bar chart, or a timeline chart.
Pie charts are displayed in the Transaction detail view and show detailed information about a single transaction ID.
To display a Transaction detail view, see the Pie charts section in the Analyzing data topic.
The following screen capture shows the Transaction detail view with the File usage pie chart selected, and showing detailed file request information for the selected Transaction ID.

Bar charts show summary information for multiple Transaction IDs. The Transaction IDs are displayed in the order in which they are shown in the selection.
To display a File usage bar chart, see the Bar charts section in the Analyzing data topic.

Timeline charts show all instances of a Transaction ID in the selected application ID across the whole data file, or a range of dates specified using the Date dialog when selecting the data.
