Regarding your specific example, as has already answered, the diagram you have provided is wrong. In summary, just right click on the diagram's background, select Sequence Number and then choose your option from the pop-up menu. Once you list down all the objects, actors, lifelines, and messages you get a complete visual representation of how a system works.Regarding on how to set different ways of numbering sequence messages in Visual Paradigm, you should read the section " Setting different ways of numbering sequence messages" from the How to Draw Sequence Diagram? guide from Visual Paradigm.Sequence diagrams show the order of interaction in a system by moving down the lifeline with each message.Messages are notations that show the information being sent between objects.This involves thinking of all the steps an actor must complete for a given task. Now start visualizing the interactions actors have with objects. Moving down a lifeline means more time is passing. Create lifelines that represent the existence of an object or actor over time.In a sequence diagram, actors are represented by stick figures and objects are represented by rectangles.While creating a sequence diagram the first step is to identify all the objects that will participate in the system.It comes with specific shape libraries with sequence diagram notations and easy drag and drop functionality to visualize lifelines, actors and how they interact with each other. Creately’s sequence diagramming tool allows you to create detailed sequence diagrams.Sequence Diagrams are used to design, document, and validate the architecture, interface and logic of systems by describing the sequence of actions that need to be performed to complete a task. More Templates What Is a Sequence Diagram?Ī sequence diagram is a UML diagram type that represents how and in what order objects in a system interact with each other.
