Adjust Variable module
D ESCRIPTION
The Adjust Variable module adjusts a variable to a target value at a specified rate. This
module might be used with the Rotate By Expression option in Global and Resource pictures
to present smooth animated rotations of pictures. It might also be used to approximate/
animate a continuous increase or decrease to a variable value over time.
When an entity enters an Adjust Variable module, the Variable Name is adjusted to the
To Value at the specified Rate. The entity is held in the module until the adjustment is
completed.
The Update Interval specifies the time interval between actual assignment updates of the
variable value over the time period of the change. A smaller update interval produces
smoother animation in plots or rotating pictures that reference the variable, as well as
more accurate time-persistent statistics collected on the variable. A larger update interval
produces faster run speeds.
