Add a progress terminal that outputs a 0-100 value representing %complete for the loop. The terminal can be enabled/disabled like the conditional terminal. The compiler would discard the code behind it if it is not used.
not that it saves a whole lot of work, but i could see labview allowing you to wire a progress bar (or any other numeric) reference into the left (input) side of the iteration terminal and getting the behavior you suggest. i can't really think of anything else that would be useful to wire INTO the iteration terminal other than a reference. thoughts?
@asco that's a good idea, but I would still perfer a separate terminal. perhaps one labeled with the % sign instead of P, which altenbach reminded me is taken.
@altenbach It is true that the computing from N and i is 'trivial', but it's also expensive if you do it often enough. Also, N is fixed in the upper left which can contribute to messy diagram. Perhaps a sliding N terminal?
@stbe The "solution" you cite is a pop-up dialog that achieves its behavior using propery nodes. I generally avoid such code.
Regarding the computation being expensive.... You think because the For-Loop has a terminal for something that it doesn't need to be calcuated? You can also calculate the % values BEFORE the loop runs. It's still trivial. But you still have N calculations to do....
By expensive I mean time and $$$, not computation. From the context of my previous post, I can see why you would take it to mean computation. Sorry for the confusion.
I typically use a property node to set the max value of the progress bar BEFORE going into the for loop and then I simply pass the i straight into the progress bar terminal (maybe with the increment depending on how picky I am being).

i like the idea of a progress terminal. it would especially come in handy when you're using parallel loops. Every time i try one of the normal means for mapping progress enumerated above for a parallel loop, it fails or acts glitchy.
