Thanks Martin, that kinda solves one problem. However, the contour
problem still remains. Take a look at
http://www.met.ed.ac.uk/~aaron/funny_lines.gif. There are lines drawn
from one edge of the plot to the other (the data when filled with the
/cell_fill keyword looks OK), just when a line contour is drawn over the
top, these parallel lines appear. They look to be where the data is
trying to connect one point to the same point, but in a different region
of the plot window?

Thanks,
Ben
