Attaching arrows in Gliffy Sequence Diagram

Question

I was using Gliffy to draw a sequence disagram But there seems to be no way to attach a "message" arrow to either a timeline or to an activation box.

Have I missed something or is this deficiency a feature of Gliffy?

Any other online or Win32 apps that can be used for a quick one-off sequence diagram where messages can be attached to timelines, activation boxes and actors etc?

Answer 1

If you just need diagramming, I think the netbeans plug-ins from VisualParadigm might do it for you: http://www.visual-paradigm.com/product/sde/

all available as feature limited free trials(registration required). The only thing they lack is code generation/db migration and the like. The diagramming is all there(or was when i used it)

Answer 2

Following Gilles comment I found Web Sequence Diagrams which follows the traditions of Graphviz but does it online.

You enter some text

note over A: text2
A->B: text
activate B
B-->A: text
deactivate B
note over A: text2

As you type, it produces a corresponding sequence diagram.

• No need to reorganise arrows manually after dragging some element around.
• No need to manually align tops of timelines

LucidChart is another online charting tool that, like Gliffy, supports a wide variety of chart types. Like Gliffy, it is based on drag & drop but allows arrows to be attached to any part of a timeline or other object. I prefer WebSequenceDiagrams.com.
