It is often necessary that the curves on the graph were not close to 
axes. I use external tools for this: the script reads the data files, 
finds min and max on the Y axis, and writes to gnuplot file something 
like this:

$delta=($maxy-$miny)/20;
$maxy -= $delta;
$miny += $delta;
print GPFILE "plot [][$miny:$maxy] ....";

Can I do this with gnuplot? If not, then I suggest to introduce 
something like "set ydistance=0.05", which means that the space between 
data curves and lower/upper X axis is 1/20 of data range.

Thanks
