I have a mix of both. On Windows I use the "Win-Gnuplot" and cygwin to
have these nice helpers from the linux/unix world.

Here is another solution with only gnuplot.

set datafile separator whitespace
set table 'space2tab.dat' separator tab
plot 'sep_space.dat' u 1:2 w table
set datafile separator "\t"
unset table
plot 'sep_tab.dat' w p, 'space2tab.dat' w p


Then you have a second dataset (sep_space.dat -> space2tab.dat) with
tabulator instead space separators. It works since version 5.2.2.
