gnuplot question

[David A. Sinck]

Hopefully there are some gnuplot users out there to field this.

[simple] Given a data file of 360 points, how do you plot a "circle"
of data points.

[goal] Given a data file of N points per day over the course of a
week, how do you make it so that the graph has alignment so that each
day starts at 0 degrees?

I know about set polar, but I'm not quite seeing how to step the
radial amount.

BTW, I ran across the amusing tidbit that apparently gnuplot is not
under the auspices of GNU as one might assume.

TIA,

David
