The problem comes from your apparent aversion to usual notation for big 
numbers, i.e. from spelling out  1*10**12 when you should have just 
written 1e12.  The problem is that 10**12, as writtten, is an operation 
on integers, so it'll be evaluated in integers.  But 10**12 is quite 
certainly larger than all integers on your machine, so this doesn't do 
anywhere near what you think it should:

gnuplot> print 10**12
-727379968
gnuplot> print 1.0*10**12
-727379968.0
gnuplot> print 1*10.0**12
1000000000000.0
