If a range has a low and high value and a name defined, and the range is
turned off, it will retain the low and high value and name when turned back
on.
User-defined ranges vs. symbols
When defining low and high values
for the State Histogram ranges, you may use symbols instead of entering
discrete values. Symbols can only be used for labels selected in the State
Histogram mode if they are defined in the Format menu, and only if the
base in the State Histogram menu is set to Symbol.
Pattern or range symbols defined in the Format menu can be used to set the
low or high value of a range.
Total samples
The total samples field displays the total number of
samples in all the displayed ranges. If Other States included is selected,
then total samples is the total of all displayed samples plus the other
states. If any ranges are overlapped and samples fall in multiple buckets,
these samples are only counted once in total samples.
Number of samples per range
Displayed next to each bar is a value
representing the number of samples for that range. The ratio of these
values to total samples determines the relative size of the histograms.
These values are updated as the repeated acquisitions are sorted and
displayed.
Other States included/excluded
Usually the defined ranges will not
cover the entire range of the specified label. The Other States included/
excluded field provides an optional histogram showing all activity on the
specified label that does not fall within any of the defined ranges. By
selecting excluded, the relative activity of only the defined ranges is
displayed. If included is selected, the "other" histogram appears under
the ranges.
If a range is turned off, any activity in that range is included in Other States.
The activity of a turned off range is included in the other range whether
included or excluded other states is displayed or not.
Trace Type: All States vs. Qualified States
State Histogram mode
can qualify data as it is sampled. Qualifying data while sampling allows
only data of interest to be stored, while the rest is thrown away.
When Trace Type is set to Qualified States, a new field appears in the upper
row of the display. The new field, Specify States, is where the data
qualification is defined. The data qualification is not limited only to the label
selected in the State Histogram menu. It is defined over all labels defined in
