通过指定状态转移时间以及动作执行时间来控制 Stateflow® 图的执行。通过广播事件同步状态执行。检测数据值的变化，并检查在图执行期间有哪些状态为活动状态。
|Chart||Implement control logic with finite state machine|
|hasChanged||Detect change in data since last time step|
|hasChangedFrom||Detect change in data from specified value|
|hasChangedTo||Detect change in data to specified value|
|after||Execute chart after event broadcast or specified time|
|at||Execute chart at event broadcast or specified time|
|before||Execute chart before event broadcast or specified time|
|count||Chart executions during which condition is valid|
|duration||Time during which condition is valid|
|elapsed||Time since state became active|
|every||Execute chart at regular intervals|
|temporalCount||Number of events, chart executions, or time since state became active|
