Expressions as Tag Parameters

Support exists in VTS to allow arbitrary expressions to be used as tag inputs for some tag types and drawing methods. The PTypeToggle widget, allows the user to choose between a tag, a constant value for a tag parameter, or a block of steady state VTS code. All tags and drawing methods in the VTS layer that use a PTypeToggle have been modified to support expressions. Supported tags include:

•      Function tags

•      Alarm tags

•      Logger tags

Supported tag drawing methods include:

•      Two Color Bar

•      Multi-color
