Dear Ox-users
I would like to plot a Boolean matrix, i.e. a matrix whose entries are
either 0 or 1. Ideally, each TRUE value would be represented as a solid
point. At present, I use DrawXYZ with the optional 'mode' argument set to 2
for a contour plot. This produces something close to what I want, except
several contours are displayed for each TRUE value, rather than a single
contour, which makes the graphic messy. Also, the upper contours are not
filled, so TRUE and FALSE are not easily distinguishable.
Any pointers on how to do this better appreciated!
