Call Graph Pane

The Call Graph pane displays a graph that represents all the sequence calls that start at the root sequence. Each sequence appears as a node in the graph, and each sequence call step appears as a link. You can expand or collapse the links for each node. The arrow on the link indicates the direction of the call, and a number on the link indicates the number of steps that call the sequence. Each node and link has a tooltip that shows more detail about the item. Each node is color-coded. All nodes that represent a sequence in the same sequence file have the same color.

Use the options on the Sequence Hierarchy toolbar to configure the layout and horizontal and vertical direction of the graph and to arrange the nodes and links. Adjust the default graph layout to your needs before printing or saving the graph to disk, if necessary.

Use the following keyboard shortcuts or the context menu to navigate through the nodes:

Key Action
Arrow left Selects the node to the left of the currently selected node. The target node can be a sibling or a parent node.
Arrow right Selects the node to the right of the currently selected node. The target node can be a sibling or a child node.
Arrow up Selects the node directly above the currently selected node. The target node can be a sibling or a parent node.
Arrow down Selects the node directly below the currently selected node. The target node can be a sibling or a child node.
<*> on the keypad Expands all nodes.
<⁄> on the keypad Collapses all nodes.
<+> on the keypad Expands the currently selected node.
<-> on the keypad Collapses the currently selected node.
<Home> Selects the root node.
<End> Selects the bottommost or rightmost node, depending on the horizontal or vertical orientation of the graph.
<Enter> Same as double-clicking on the node.
Context Menu Shows the context menu of the selected node.
<Shift-F10> Shows the context menu of the selected node.

Double-clicking a node opens the sequence in the Sequence File window. Double-clicking a link opens the sequence in the Sequence File window and highlights the Sequence Call step to which the link corresponds. When multiple Sequence Call steps call the same sequence, a number that equals the number of sequence calls displays on the link. Double-clicking a link that shows such a number launches a combo box, in which you can select the Sequence Call step you want.

If you use expressions to specify a sequence call, TestStand evaluates the expressions while building the graph. TestStand creates a sequence context using the call step. If TestStand cannot evaluate the expressions, an expression node appears on the graph. Right-click the expression node and select Specify Sequence Call Expressions from the context menu or double-click the expression node to launch the Specify Sequence Call Expressions dialog box, in which you can replace an expression node with any sequence. You can also drag and drop a sequence on an expression node, which is useful when you work with unsaved sequence files.

Note Note  If you override a Model callback sequence in the client sequence file, the node tooltip indicates in the Callback Overridden item if the callback is overridden. This node tooltip item appears only when you select Display Hierarchy Using»<Entry Point Name> from the Steps pane context menu, Sequences pane context menu, Workspace pane context menu, or Windows pane context menu to view the hierarchy from a process model entry point. Double-click the node of the overridden callback to open the callback sequence of the client sequence file in the Sequence File window. However, if you use an expression to override a Model callback in the client sequence file, the node tooltip does not display any information about whether the callback is overridden.
