OK, thanks for this information, I didn't know that.
But I think it only solves part of the problem as I still need to create 
at least one graphic window.
Using pixmap='on', I can easily reuse the same window for all my plots 
and I think I can get things faster.
But I cannot do batch plotting on a station without X server...

Thanks anyway,

Antoine
