The Y axis is the relative number of occurrences in each bucket.
Maximum value of the Y axis is constantly updated to reflect the number
of occurrences in the bucket that has the most occurrences, and is
displayed as "Max count."
The total number of states sampled for the selected label is presented as
Total count. This includes states that may be outside the user-specified
X axis range.
Two markers are available on the X axis to determine the range of a
bucket and number of occurrences in any bucket.
Choice of base for a specified label is user-definable.
State Histogram
The State Histogram mode displays states that occur
within user-defined ranges of a label. State Histogram is available on any
label defined in the Format Specification.
Maximum number of ranges is 11.
Other States included/excluded is available and displays a histogram of all
states not covered by the user-defined ranges.
You can trace All States or patterned Qualified States.
Total samples displays the total number of occurrences in all displayed
ranges.
Choice of base for specified label is user-definable.
Time Interval
The Time Interval mode displays time intervals between
user-defined start and end events.
Start and end events can be defined over all labels defined in the Format
Specification.
10 ns is the minimum sample period and time interval resolution.
The maximum number of time interval ranges is 8.
Time interval range size is 10 ns to 9,999,999 seconds.
Calculated statistics provides Maximum time, Minimum time, Average
time, and Total number of time intervals sampled (one time interval
defined to be a paired start/end event).
Auto-range feature automatically scales the eight time intervals over
maximum and minimum times using a logarithmic scale or linear scale.
Choice of base for labels is user-definable.
