The Pathway Diagram

The Transition Pathways Property contains a custom editor called a Pathway Diagram.

alt text

A Pathway Diagram lets you edit:

  1. The State Classes for a Stratum
  2. The States and Transitions between those State Classes.

The boxes in each diagram represent State Classes and the lines represent transition pathways. Green lines are deterministic transitions and blue lines are probabilistic transitions.

Using the Toolbar

You can use the toolbar at the bottom of this window to interact with the diagram in a variety of ways:

  • Use the Tab Control to select the current Stratum.
  • Use the Tab Navigator to search for a specific Stratum.
  • Scroll and zoom the current Stratum using the scroll and zoom controls.
Note

The last two tabs, States and Transitions, are special tabs. These tabs show the Transitions for all strata combined. Here, you can edit the Transition records directly, cut and paste multiple records, and import records from a variety of data formats.

Editing State Classes

The Pathway Diagram lets you edit the State Classes for the current Stratum. For example, you can add a new State Class by choosing Add State Class... from the diagram's Context Menu.

Each State Class in the diagram can be moved to a new location by dragging it with the mouse. You can also select multiple State Classes and move all of them at the same time.

There are two ways to select multiple State Classes:

  • Hold the left button down and drag the mouse to create a selection rectangle.
  • Hold the CTRL key down and click on the individual state classes.

When you have at least one State Class selected you can also cut, copy, paste, and delete them. These options are available from the diagram's Context Menu and from the main window's Edit menu.

Note

The Pathway Diagram must have the input focus or the Edit menu items will not be enabled. You can tell that the diagram has the input focus when the selected State Classes are blue instead of grey.

Editing Transitions

When you have at least one State Class selected, you can choose Open from the Context Menu. This will display the State Class Editor where you can edit the transitions for those State Classes.

Note

You can also open the State Class Editor by double-clicking on a selection of State Classes.

Other Options

The following additional options are available from the Context Menu:

Item Description
Show Grid Shows a grid on the diagram to make it easier to organize your State Classes.
Show Tooltips Shows tooltips for each State Class as you hover over them with the mouse.
Edit State Class... Lets you do an "in-place" edit of the Class and Subclass for a State Class.
Filter Transitions... Lets you choose which Transitions to display in the diagram.
Select Stratum... Lets you navigate to a different Stratum in the diagram.
