Thanks for the answers! Both
plot3d(floor(min_symbolic(x, y)),(x,1,7),(y,1,7))
and
plot3d(lambda a, b: floor(min(a, b)),(x,1,7),(y,1,7))
produce the right plot.
I wonder whether the result of ?min might mention the existence of
min_symbolic, and similarly for max. When the first attempt failed, I
looked at what ?min said, and didn't get much out of it. Had it
mentioned "see also min_symbolic" or something of the kind, that would
have been a clue.

Hi Fernando,
I believe that problem is that:
sage: min(x, y)
x
It may be less than ideal, but given that "min" is a built-in function
which by the looks of it just picks the first element from its
argument such that other elements are not strictly less than it, it is
as documented.
There is min_symbolic for symbolic operation. If you care about
performance, there may be a difference between using min_symbolic and
using a "lambda" argument to plot. You'd need to try to see which one
is faster for your application.
