| This is still under construction. You can propose new features if you need some. You declare participant using the following keywords, depending on how you want them to be drawn. |
You define state change using the
| Keyword || Description |
| An |
analog signal is continuous, and the values are linearly interpolated between the given setpoints
| A |
binary signal restricted to only 2 states
| A |
clocked signal that repeatedly transitions from high to low, with a
period, and an optional
| A simplified |
concise signal designed to show the movement of data (great for messages)
| A |
robust complex line signal designed to show the transition from one state to another (can have many states)
@ notation, and the
is verb. [Ref. QA-14631, QA-14647 and QA-11288] It's also possible to have binary and clock signal, using the following keywords:
You can add message using the following syntax. It is possible to use relative time with
@. Instead of using absolute or relative time on an absolute time you can define a time as an anchor point by using the
as keyword and starting the name with a
@XX as :<anchor point name>
Rather than declare the diagram in chronological order, you can define it by participant. You can also set a specific scale. When using absolute Times/Dates, 1 "tick" is equivalent to 1 second.
You can also define an inital state. A signal could be in some undefined state.
Intricated or undefined robust state
Intricated or undefined binary state[Ref. QA-11936 and QA-15933] It is also possible to hide some state.
[Ref. QA-12222] It is possible to hide time axis.
It is possible to use time or date. It is possible to display time constraints on the diagrams. You can higlight a part of diagram.
You can use the
note top of and
note bottom of keywords to define notes related to a single object or participant (available only for
concise object).[Ref. QA-6877] You can optionally add a title, a header, a footer, a legend and a caption:
Thanks to Adam Rosien for this example.
You can add color. [Ref. QA-5776]
Without style (by default)
With style You can use style to change rendering of elements. [Ref. QA-14340] You can use the
<style> tags and sterotyping to give a name to line attributes. [Ref. QA-15870] You can use
compact command to compact the timing layout.
