Actually yes. Gnuplot understands hexadecimal (and octal), the
number just needs a preceeding "0x" (or "0") marker. You just have
to add it in your "using" statement, and then take advantage of
gnuplot´s automatic type promotion:

$dat << EOD
11c 4
12a 5
133 4
13f 6
1aa 1
EOD

pl $dat us (("0x".strcol(1))*1):2 w l

Admittedly, I was very doubtful too before seeing the above example
actually producing a plot. ;)
