Sketch of what I am trying to do:
I have a base graphic. If a certain part of a calculation found a result, I want to add another "piece" to that graphic. If no result was found, I don't want to add that piece.
So I'd like to write code like this:
Show[
base graphic,
If[result_found, piece,(* else *) NullGraphic]
]
So if result_found is True, it behaves as
Show [
base graphic,
piece
]
and if result_found is False, it behaves as
Show[
base graphic
]
So the question is: Is there anything I can use where I wrote "GraphicNull" above? I already tried "Null" ... doesn't work.
Thanks ....
