Yes, it was exactly in this point that I was with doubt.

Thanks for the answers.

Best regards,

OK, now I understand what you are asking.

No, what you are trying to do is not currently possible.  Right now NDArray attributes are limited to being scalar quantities, not arrays.  There has been some talk of adding support for 1-D array attributes to NDArrays, but this is not in the immediate future.

I am using NeXus plugin from EPICS Area Detector.
I managed to save others EPICS PVs by configuring the XML files, but for waveforms it didnt work.
Is there a way to do this with these tools?

Which tools are you using?
EPICS Area Detector?
Python code?

It is generally possible to collect a waveform record from EPICS and
write it to a NeXus data file with client programs written in various
languages such as C++ or Python.
