shading in contour plots [message #44648]

Hi,
Is it possible to create an accurate, filled contour plot with data
which does not vary smoothly?

Im trying to create a contour plot of trend data. I would like to add
some shading in a single colour to indicate where the trends are
significant, i.e. I have a 2-d array filled with 1s and 0s, and call
contour with this array and the /cell_fill keyword. If I use
levels=[1], I get a plot composed of large rectangular patches, even
though the data is rather finely gridded, and the significance is not
distributed in large rectangular areas. If I change the levels to
levels=[0.1,1.], the plot looks completely different (much larger
shaded areas), despite the fact that there are only ones and zeros in
the array I'm plotting. Anyone got an idea of what Im doing wrong
here?
Cheers,
Chris.
