I'm guessing that the problem is that the horizontal segments coincide
with the edges of the plot window, so they aren't visible.
How about this:
plot2d (unit_step (x), [x, -1, 1], [y, -1, 2]);
which sets the plot window so that it's more extensive than the
plotted function.

You'll have to be more specific about this.
