[plt-scheme] newbie - plotting points

Following up further, it turns out that "help desk" is not some place in
meatspace, but a fancy GUI doohickie that you can access from the DrScheme
GUI under "help", and that if you search for help on "plot" it
automagically downloads something, gives you help and generally "just
works".

(require (lib "plot.ss" "plot"))
(plot (line (lambda (x) x)))

(I don't seem to be getting emails from the list, only replies copied to
me; I hope I've not broken something or used the wrong address).

Anyway, thanks again,
Andrew
