Gliffy Sequence Diagram

The Gliffy editor includes a drawing canvas, a toolbar, and shape libraries.

An alternative combined fragment is used to specify an area of a group of lifelines/ actors to show conditional flow in a sequence diagram. It also models the if-then-else logic in the sequence diagram. In this article, we will demonstrate how to draw a simple sequence diagram by using an alternative combined fragment. This dynamic diagram is based upon a UML communication diagram (previously known as a 'UML collaboration diagram'). It is similar to a UML sequence diagram although it allows a free-form arrangement of diagram elements with numbered interactions to indicate ordering. Scope: An enterprise, software system or container. But where there’s the possibility of ongoing maintenance, it’s safer and simpler to use a tool like Gliffy that supports editing the diagram as part of the wiki page. What Gliffy looks like. Gliffy diagrams appear as JPEG images on the wiki page. If you have permission to update the wiki page, you’ll see an “Edit Diagram” link below. Lets take an example of sequence diagram for an ATM machine.Let's say here you want. IF card inserted is valid then prompt 'Enter Pin'.ELSE prompt 'Invalid Pin' Then here is the sequence diagram for the same. Hope this helps!

Drawing canvas

The drawing canvas is your canvas where you build your Gliffy diagrams. Drag shapes from a shape library or create new objects using the toolbar to customize your flowchart, diagram, schematic, wireframe, floor plans or whatever else you desire. Use the bottom and side scroll bars to move around in larger diagrams. Hold down the spacebar while you click and drag to pan around the canvas. And, if you have a mouse with a scroll wheel, you can use that, too!

Shape library

Sequence diagram tool

Gliffy includes a wide range of shape libraries to help you build your diagrams, such as basic shapes, business process, software and network design, and floor plans . You simply drag and drop any shape from any library right onto the drawing canvas. You can also add your own custom shapes, logos, and images to a custom library. See Shape libraries.

The toolbar

The toolbar at the top of the Gliffy editor lets you select tools to create lines (see Lines and connectors), shapes (see Shapes) , text (see Text) and to format and manipulate them (see Manipulating objects).

Right-click menu

Another way to work faster with Gliffy is to use the right-click, or context menu, to access commonly-used commands. For Mac users, control+click. The options shown vary based what object you selected.
