Dear David, which version or Artemis do you use?

In the older versions, you may use the "save current group(data) as ... function"

In the newer versions, there is an option in the plot window  - save next plot to a file"

Both should work out!

Cheers, Dirk

 Dear Rezaeipour, 

I have read the instruction about Artemis, but I don't find it. Thank you very much.

David

Dear Dirk, 

Thanks a million, I have solved it. You are so grateful. I use Artemis 0.9.25.

Wish you enjoy work.

Cheers, David

You're welcome!
