Sample List Histogram Print
1. Time and Date of Print
At the top of Histogram Print, is the time and date
when the histogram was created.
2. Results
The name of the test result that is being
histogrammed is followed by a list of the values
for that result. Each of the values (separated by
commas) indicates the value for the corresponding
time period. In the example shown, in the 36th
group of 255 seconds of the time covered by the
histogram, 6643 bit errors were detected; in the
following 255 seconds of the time covered by the
histogram, 2699 bit errors were detected; and
so on.
