Yes, this is clear, but what you state above is not correct: if I do this

plot sin(x)

on a wxt terminal, then I get this
 GPVAL_TERM_XMIN = 1215
 GPVAL_TERM_XMAX = 12394
 GPVAL_TERM_YMIN = 678
 GPVAL_TERM_YMAX = 7355

while my window is only 640 X 380 pixels. I think, the number of 
pixels is multiplied by 20, and that gives GPVAL_TERM_XMIN and 
the like. But is this 20 a universal number? If I change to a 
different terminal, can I still trust my numbers?
