Sum readings over an inner loop, reset to zero at each iteration of an outer loop

[ChrisHodgesUK]

I feel this should be simple, but I must be missing something.  Searches are failing to give me anything useful

I've got a for loop inside a while loop.  I want to sum values (readings from a multimeter) as the for loop iterates, then start summing again at the next iteration of the while loop.

A bit more background:

* Afterwards I divide by the for loop count (specified on the front panel) to get an average, then write that to a file - that's easy.

* Within the for loop I toggle one of the applied voltages, so I'm actually building up two sets of data, which is why I can't use the averaging built in to the instrument as I previously did.

* I'm coming back to LabView after several years, so recalling some of the tricks isn't happening

It would be easier to advise you on what to do if you could attach your code (actual code is preferred, but a screenshot is better than nothing). I think that your code can be significantly simplified.

One option that I would consider is to collect your data points in the for loop into an array and get the average outside of the loop.

I'll have a fiddle with arrays in a minute, thanks.  The number of elements will be small enough not to have memory issues but I hadn't considered it because I don't need the elements

As for the code, I'm in the process of adding the inner loop into some existing code so there's nothing even sensibly screenshottable for now.  I may have to build something from scratch for testing/sharing if your suggestion isn't enough of a pointer

Use a shift register on the FOR loop to keep your running sum.  You can then divide after the loop to get the average.  You just initialize the shift register to 0 before the FOR loop.
