I would suggest something like:

plot "<( awk '$1 > 0 && $1 <= 3' my.dat)" ...

The above would ignore the order of the values in the first column and 
also plot in case of multiple occurrences of 1, 2 or 3. There are other 
AWK-Oneliners for only plotting the first occurrence of something, the 
last one, a random one, etc.

Occasionally, people in this group recommend to do data pre-processing 
with AWK and similar tools and use gnuplot for plotting only. I can only 
agree.
