I'm not aware of the limitations of the tools you're talking about,
but you can transform your scatter "set" to positive if need be (i.e.
moving the origin in the x,y negative direction temporarily).  This
shouldn't be that much of a problem unless your distribution distance
is large and your data is severely clumped (like a Pluto orbiting way
out there in a solar system with a bunch of planets hanging close to a
small star).
