Except the leftmost time unit, you can drag and relocate all time units. Repeat step 12 and 13 for more time units.Double click the time unit to add a caption.We will then see a tiny vertical line (the time unit) appear at the bottom of the frame. Right click on any empty space in the timing frame, and click Add Time Unit.You should see a diagram like this after adding lifelines and states:.Repeat step 7 to 9 for creating more lifelines and state or conditions.In this tutorial, we will be renaming this state to Idle. Double click State/Condition and rename the state or condition.Right click Inspector and select Add State/ Condition to create a new state or condition. Double click Lifeline and rename the lifeline to Inspector.Right click the frame and select Add Lifeline to create a lifeline.Double click the word Frame on the timing frame to rename the frame.Select Timing Frame, then click or drag on the diagram to create a timing frame.We will name the diagram Select Timing Diagram in this tutorial. You can use the search bar to find the diagram. In the New Diagram window, choose Timing Diagram, then Click Next.Remind that the start and the end points of each arrow indicate when each message was sent and when it was received.Model the messages sent from one object to another can be depicted using simple arrows.The state will be changed over time indicated by the timeline. Each object has a set of possible states.Put one life line with a number of possible states above the other vertically, and the passage of time (say in seconds) horizontally.Stack several life lines of different objects in the same timing diagram.The steps below outline the major steps to take in creating a UML Timing Diagram. The UML timing diagrams focus on the specific timing in which the messages are sent from one object to another and on the specific timing in which objects change their state. Timing diagrams are common when dealing with real time systems.
