摘要:
A method and tool for indicating dependency in a graphical program or a dataflow diagram is provided. The method comprises determining nodes that are affected by a selected node of a graphical program or a dataflow diagram and determining nodes that affect the selected node. Dependency data relating to the selected node is displayed to a user by indicating the nodes that are affected by the selected node and/or the nodes that affect the selected node. By using the tool, the a user can navigate through the graphical program or the dataflow diagram to find where there are signals, nodes or modules that are dependent in some way on the selected signal.
