Butterfly Graph Key

The butterfly graph is unique in that it was written with our Perl API and shows different things for many different entity kinds. For example if you select a function it will show the call/callby relationships, and if you select a file it will show the include/includeby relationships. Here’s a list of the relationships it currently shows:

  • Call/Called By
  • Base/Derived From
  • Extends/Extended By
  • Includes/Included By
  • Use/Used By (VHDL)
  • Perform/Performed By (Cobol)

So for each of these relationships¬†a red box is the starting/selected entity, a blue box is a known entity that Understand has the source code for, and a grey¬†octagon is an unknown or unresolved entity that Understand doesn’t have the source for.
