Block diagram metrics, available in the LabVIEW Professional Development System, appear in the VI Metrics window when you place a checkmark in the Diagram checkbox. The following metrics specify the block diagram of a VI and its structures and wires:

  • structures —Number of For Loops, While Loops, Case structures, Event structures, Flat Sequence structures, Stacked Sequence structures, Conditional Disable structures, and Diagram Disable structures.
  • diagrams —Number of block diagrams. Each VI has a single top-level block diagram. In addition, it has one subdiagram for each loop or structure.
  • max diag depth —Deepest nesting level of block diagrams in a VI. If the VI has no structures, it has a depth of 0.
  • diag width (pixels) —Width of the block diagram in pixels.
  • diag height (pixels) —Height of the block diagram in pixels.
  • wire sources —Measures the total number of sources in the VI. Each wire has a single source but can branch to multiple destinations. If a wire enters or exits a structure, LabVIEW considers the tunnel that the wire passes through to be a new source.
