collector output garbage when written to file?

[aem64]

Hello,

I am trying to average dynamic data over the course of 5 seconds and write the average of those 5 seconds to file at the push of a switch. 

I have figured out how to get a switch to turn on for five seconds and then turn off when switched, but I am having a hard time figuring out how to average the data and write one line to the output file.

I have tried using the Collector Express VI paired with the Statistics VI, but the output is acting strangely.

I have attached what that output looks like here as test1

I would like to use a while loop with a shift register to make this work, but I am not sure how to advance.

Any Ideas?

I could not attach the file for unknown reasons, here is a screen shot of what it looks like.

Hi aem64,

It appears that you the data you converting to Dynamic Data is of type Double.  A double is a single value and not a collection of data over time.  Attached below are links to some examples that will hopefully prove to be useful.  One uses shift registers to average data over a certain number of iterations, while the other shows how to use a shift register to build an array of collected data over a period of time.  I hope this helps!
