Individual Transaction Percentiles/List 

This screen lists instances of the active transaction that HP SPT/XL
found in your program, so you can get to a specific instance of a
transaction.  The screen may show a range of CPU transaction times or
processing transaction times.

For example, looking at band 8 shows transactions with CPU processing
times in the 70th-80th percentile.  You can choose instances to examine
from within that band and continue to refine your choices until you are
looking at a single instance of this transaction on the Individual
Transaction Intrinsic Profile screen.  You can then look at an intrinsic
trace for that instance of that transaction.

Access this screen by selecting  Individual Trans to display the
Individual Transaction List screen (if only a few instances of the
transaction exist).  If there are many instances of the transaction, you
will see the Individual Transaction Percentiles screen.

 Compare                  Compare transactions in one band against those
                          in another band.

 Show by CPU              Show percentiles based on CPU use instead of
                          processing times.

Selecting  Compare from the Individual Transaction Percentiles screen
lets you compare transaction instances in one percentile band with those
in another band.  Selecting  Compare from the Individual Transaction List
screen lets you compare two instances of a transaction.
