Spectral Signatures - training samples

Can I represent the spectral signatures from training samples?

I don’t know how your training samples look like.
But you could, for example, write a CSV file. And this can be read by SNAP. You can find information about the format in the help.

Sorry, maybe I was not clear enough.
I created training samples (polygons for six thematic classes) using “New vector data” with Snap interface.
Afterwards, I would like to represent them at “spectrum View”

You mean an average spectrum of all pixels within the shape or all at once?
No, both options are not possible.
