Control via Tags, Expressions and Parameters
VTS gives you a wide selection of methods for controlling each property of a graphic object. This range of control allows you to create screens that can be static or that can respond dynamically to show changes in system conditions.
Referring to the following image, every graphic property has a drop-down menu of control methods. The first choice in each list is always the native data type for the value. In the example shown here, it is Color. For other properties, it might be Width, Line Style or Tag Type as matches the property being set.
The following topics describe how to use each of the available control methods.
