That has surprisingly few commas and semicolons for a csv file :-)

No.

There's the "send the data through an external program before use"
function, but that's not terribly useful if you know no external program
to do that kind of transformation job for you.

In the Unix environment gnuplot originally grew up in, it would work
roughly like this:

  plot "< awk -e '{printf \"%d\", strtonum (\"0x\" $1)) }' yourfile.csv"

If you do have an 'awk' command around, that should actually work even
on Windows.

OTOH, if it's actual CSV and you're on Windows, you might want to follow
the saying "when in Rome, do as the Romans" and just perform the
transformation in you preferred spreadsheet program...
