Ok, I wasn't very specific:

If you want to manipulate the values in a column, you can use either 
column(3) or its shorthand $3. However, if you invoke gnuplot from a 
shell using heredocs (<<eoi), like in your example, the $3 is 
interpreted as a shell variable. You could of course escape the dollar 
sign, but IMHO the best way is to use column(3) in that case which makes 
you independent of the environment.
