FactoryTalk Historian ProcessBook allows you to create custom
placeholders for a symbol based on a summary Data Set or a FactoryTalk
Historian tag placeholder in an ODBC data set. Placeholders are not allowed
for expression Data Sets. The Custom Placeholders button in symbol definition
dialog box boxes allows you to specify different FactoryTalk Historian tags for
a FactoryTalk Historian Summary Data Set or ODBC data set with a
FactoryTalk Historian tag placeholder. The change applies only to the
configured symbol. See
Add or Edit Placeholders (page 259) for details.
Bar Scales
The options under Scales control how the bar symbol shows scales.
Defaults
The default is to show scales inside the bar symbol in General number
format for symbol bars created with FactoryTalk Historian ProcessBook
3.2 or later. For earlier versions of FactoryTalk Historian ProcessBook,
Show Scales is not selected, and scales do not appear on the symbol bar.
The scale values for the bar symbol are the Upper and Lower or Right
and Left values in the Define Bar dialog box for both tags and datasets,
including AF.
