@datapoint = splice(@values, 0, $x);

So you take $x items from from @values, and assign it to @datapoint. How many values will @datapoint have at the end? Right, exactly $x. Which is 1, in your script.

Update: BTW this is a bad idea: while (read(FILE, $buf, $recsize) == $recsize) {

The last chunk of the file might be shorter than $recsize, in which case read returns a smaller number. The body of the loop is then skipped. If you want to read all records from your file, just say 

while (read(FILE, $buf, $recsize)){
   ...
}
