From: Niles [mailto:niels.martinsen at gmail.com] 
Greetings, friends

I have the data-points {1,2,3}, {4,5,6} and {7,8,9} and I wish to plot
them in a 2D-plot (x,y) ranging from x:0..2 and y:-2..0. The
coordinates of the points should be

1: (0,0)
2: (1,0)
3: (2,0)
4: (0,-1)
5: (1,-1)
6: (2,-1)
7: (0,-2)
8: (1,-2)
9: (2,-2)

Is there a smart way of doing this? is it furthermore possible to make
the data-points larger, i.e. so there is no white-space between the
points? Any hints/help will be greatly appreciated.

Sincerely, Niles.
