I try to reduced the version of VI to 11.0(here I want to ask LabVIEW will generate the old version of VI in the folder?) .

As you said, I also think my code is too complicated in the implementation algorithm. would you mind providing me some links of relevant LabVIEW tutorials? Thank you very much for your patient guidance ~

While you probably saved for previous, you still attached the 2021 version. The previous version will be in a subfolder. Saving for a previous version will generate a new hierarchy. It won't overwrite the original of course. That would be very bad!

Have you studied my example above?

There are a lot of learning resources listed at the top of the forum.

thank you so much! Your program let me benefit a lot!

I'm so sorry for my fault, I just tried it again.This time I see that the new VI file has gone down from 29KB to 21KB, and I think I have succeeded.

Some quick hints about your mistakes and unnecessary complications.

(Of course you first need to ensure that N plots exists. You cannot set a property for nonexistent plots. Compare with my code)

Thanks a lot for your valuable modification opinions! I will modify my program according to your opinions and reference procedures.
