I am just confused, back to my original question... How can I pull aquired data from a subvi into a local variable/array that i can then manipulate and then display in a variety of ways?

The buffer for you DAQ device is a hardware buffer.  A queue is a software buffer.  They are similar in that they are first in, first out,  but where they are located is different.


Did you try putting a while loop around the part of yourd code in the main VI like I stated in messages 4 and 6.  Not that I recommend going that route, but it answers your question about subVI's and local variables.

I tried the while as you suggested.  It does not work.  the intensity graph will update ony if i interupt the continuous daq (with a stop).  basically the same behavior as bofore if i start and stop the main program

Attach your latest VI's that you say don't work.


I believe it will, but only if you truly did what I was trying to tell you to do.
