How to implement moving (linear) averaging in a subVI with dynamic data?

[vlee]

I was wondering how to implement a moving or rolling linear averaging using a subVI on a set of dynamic data coming from the DAQ Assistant or a counter input channel that will be written using the Write to Measurement File VI?  Below is an example of what I mean.

You could use the MeanPtbyPt vi to give the running average.  Assuming your code snippet is inside a loop, wire an =0? comparison of the iteration number to the initialize input to reset the value and put 25 (or whatever you want) as the sample length.
