Since you have not specified a font, the program will use Helvetica 
by default.  But Helvetica is a proportionally-spaced font, 
which means that adding a fixed number of spaces will never line 
things up the way you want.
You would have to use Courier or some other fixed-width font.

That command makes no sense.
First problem:
   'using (\$1)'
will cause an error "illegal character". I guess you just mean
   'using 1:2'
Second problem:
You cannot give a title that depends on $1, because the title
is not something that is re-calculated for every line of data.
The program will complain "undefined value".  I don't know
what you are trying to do, but this command will not work.
