Tks Michael,

from your answer I understand there is no way to do the same directly 
from  Gnuplot command line under Windows.
This way needs to pre-prepare data so that you lost the power of the 
interaction.

Under Linux piped input helps, so tath from Gnuplot command line you ca 
do the same you well eplained staying into the application.

I don't know if under windows, customizing something, could be possible 
enable the piped input.

In any case thanks for your answer.
