Share indicator between case structures

[thnguyen24]

Hi,

I have a boolean case structure. Inside each case, there's a for loop. Inside the for loop, there's an indicator to display data of each iteration. I want to have only 1 indicator to display data.

The problem is, I can't take the indicator outside, because then it wouldn't display data after each for loop iteration. If I leave the indicator inside the for loop, then there're more than 1 indicator to display data of each case.

Please help.

You can use a local variable of the indicator in the other cases

However, I question if your logic is inside out.  Perhaps the loop should be on the outside, and the case structure inside the loop.

I would recommend looking at the online LabVIEW tutorials

Actually, my system is not that simple.

I have a boolean case structure. Inside the true case, there's a for loop. Inside the false case, there's another boolean case structure. Inside the inner case structure, the true case has a for loop while the false case has nothing. The indicator I want to share is inside the 2 aforementioned for loops

Ravens is right. Please post your VI so we can help you avoid some common beginner mistakes.

When people talk about loops inside other structures, and wanting to update an indicator inside a loop, I visualize they have some while loop that runs for some indeterminate amount of time, perhaps a long time.  I don't expect it to be For Loops.  I consider For Loops something that generally does not wrong for a long time (unless you have some very large dataset you are operating on.)  A For Loop runs N times, runs fast, and generally returns pretty quickly.  There usually isn't a reason to update an indicator inside of it on each and every iteration.

Thanks everyone,

I redesigned my system a little bit, and I no longer have this problem.
