I have selected "clear indicators when called" in my VI properties, execution. Still, each time I call the VI, the array of data grows. My main VI sets up my UUT, and then call's the sub-VI that sets up an instrument to take measurements, then reads the results and passes the data. I then change the UUT to the next state and repeat the same sub-VI task to get the same measurements again. The main VI changes the mode of the UUT three times hence, calls the sub-VI three times. The final call of the sub-VI returns all three sets of data together, which is OK. My problem is, when the main VI finishes and I run another UUT, I get the new set of data along with the complete list of data from the previous run. I found a similar problem answered here on the forum that suggested I should "clear indicators when called", and so I did that. It still did not fix my problem. Any Idea?

Initializing the array with 0's cleared everything as needed. Thanks.

Be careful with the terminology. You initialized with an "empty 2D array", not with "0's". Big difference. 😉

Very simple. I will nail down the array thing soon. For some reason they are a little intimidating. Thanks for all the help.
