Not a formula.  By default the axis range is extended to the next tic mark.
What that is depends on "set ytics".  If you do not want the axis range
to extend beyond the actual data, you can use the keyword "noextend".
I.e.
   set yrange [*:*] noextend
In that case the axis range will exactly match the min/max of the 
data y coordinates,.

See "help noextend"
