Option This field allows you to toggle among three different types of
information about your data source.
 Data
Shows recorded values for a selected symbol's time range. By
default the table is sorted on the time stamp column in descending
order.
 Questionable (Q)
The event value is unreliable or the circumstances under which
it was recorded are suspect.
 Annotated (A)
An annotation has been made to the event to include further
information or commentary. You can
add annotations (page
196) to FactoryTalk Historian tags using FactoryTalk Historian
ProcessBook, if you have permission to write to that tag on the
FactoryTalk Historian server.
 Substituted (S)
The event value has been changed from the original archived
value.
 Statistics
Shows a table of available summary values available, for example,
Average, Minimum, and Maximum. Selecting this option disables
the FactoryTalk Historian Annotation Maintenance controls.
Available statistics vary for each symbol type.
 Point Attributes
Shows an alphabetized list of
FactoryTalk Historian point attribute
values (page 341). This option is only available for FactoryTalk
Historian tags. Selecting this option disables the FactoryTalk
Historian Annotation Maintenance controls.
Each view option provides the following controls:
The name of the symbol selected on the display is shown above the
data table.
Refresh Refresh data in all tables. Data shown does not automatically change
after a symbol is first selected. You must use refresh to view any
updates in the Details window.

visible rows.
