Activation width

The 'Activation width' property determines how wide Trace Modeler will draw the message activations.

There are three possible values : Small, Medium and Large.

It is one of the diagram style properties, the examples below demonstrate its effect on a diagram.

For a visually pleasing diagram, whenever you change the 'Activation width' property you should consider adjusting the 'Message spacing' property as well. The interplay of these two properties has a great effect on how a diagram looks.

To change the 'Activation width' for a style

  1. Open the 'Diagram Style' window
  2. Select the desired size in the 'Activation width' dropdown list
