Histogram Help

[Brians6]

Trying to dial in the maf, i took a log and saved it to come back to later. However when i opened the log file again the histogram file was not populated anymore and i was wondering if there is a way to populate it again without taking another log.
The helpfile says this about histogram displays

"Histogram Display
Whenever the histogram window is open, it will update. The histogram window will not be updated in the background if you do not have it open. If you wish to view the histogram of a portion of your log file or a certain instance in your road scanning, open the histogram window at the time you would like it to start updating. Every time the histogram window is opened it starts fresh and blank"

So does this mean once i close the hist. display i can only come back and look at a certain portion of the log and not the whole thing or am i misunderstanding something?
