That would need:

1. gnuplot can draw data from memory

2. gnuplot can save its current status of 'set' to recover from the current
temporary plot setting


Nb 2, alias "push and pop current set status" would be nice, but
unfortunately it is not so structured. For now, using temporary save help is
quite easy.
