An elementary sign relation is an ordered triple 
But what is the significance of that ordering?
In any presentation of subject matter we have to distinguish the natural order of things from the order of consideration or presentation in which things are taken up on a given occasion.
The natural order of things comes to light through the discovery of invariants over a variety of presentations and representations. That type of order tends to take a considerable effort to reveal.
The order of consideration or presentation is often more arbitrary, making some aspects of the subject matter more salient than others depending on the paradigm or perspective one has chosen.
In the case of sign relations, the order in which we take up the domains

The first time I saw this figure I assumed the triangle was on the O-S plane. Now I see the triangle can be in neither but in a different dimension or in another plane. That plane would be made more visible if there were a frame around the figure that belonged as part of the figure. Any clarification?
That’s a hasty sketch, drawn up for a conference talk, probably at a time when I didn’t have my usual graphics utility, and maybe smushed up in transit between a Mac and a PC. The published version is prettier.
But you are right to intuit that the central “spot”, as Peirce called it, is located on a different logical plane, since it is really a place-holder for the whole sign relation or possibly the individual triple. Normally I would have labeled it with a letter to indicate the whole sign relation, say
or else the individual triple, say
