Stateflow    
Behavioral Properties
Behavioral properties affect the behavioral aspects of the Stateflow chart. They change how the chart behaves in the execution of its diagram.

See also Behavioral Methods.

For a key to the abbreviations for object types in the Object column, see Reference Table Column Descriptions.

 C
LabelString
 String
 RW
 Label for this object. Equivalent to typing the label for this object in its label text field in the diagram editor.
 S B F T
SampleTime
 String
 RW
 Sample time for activating this chart. Applies only when the UpdateMethod property for this chart is set to 'DISCRETE'
( = Sampled in the Update method field in the Properties dialog for this chart).
 C
