I'll have a look.

Meanwhile as you probably found, you can "fix" the output with

    set xtics nomirror scale 0.5

It's also a bit weird that "set xyplane at <foo>" is actually
acting as if it were "set xrange [ low : high + foo ].
I worry that setting <foo> to anything other than zero may
have other unexpected side effects.
