Clear array

[pecetowiec_28]

Hi!

I'm creating a big project in LabView (I work with state machine) and I have a problem with one part of it. This is related with clearing array. When I press button "play", I start measuring. When I press button "jump", I add another measurement (here random number). But when I press button "refresh" I want whole array to be cleared. However, it only clears for one measurement period. Later, the old values come back up again. I think it can be related with "feedback node". In attachment is separated part related to clearing array.Does anyone have any idea how to fix it?

Thank you in advance

The data is in the wire (and feedback mode), not in the indicator, so clearing an indicator has no effect. I strongly urge you to go back to basic LabVIEW tutorials because most of your code is extremely ill conceived.

See if this can give you some ideas....

Thanks for your help!

But in your programm, when I press button "refresh", I get after only zeros in the array. I want to have still the random number (also after refreshing)

No, you get an empty array, there are no elements containing zero. You can easily modify the code to show whatever you want. Which random number do you want to see? (The array often contains more than one.)

It is difficult to come up with a solution if the requirements are not well defined.

I modified slightly your programm and I get what I want.

So thank you very much for your help
