AHhaha, just tried it: it doens't work. I confused '=' functions with '>' and '<' functions.
Sorry :s
Have you tried > or < either? IIRC you can't have any Y= equation with Y inside, no matter what extra graphing app you have installed. It wouldn't work anyway since it's not a function. And X= only takes single constant values. If you want to graph a complete X= equation, use DrawInv . It doesn't actually make a graph that you can trace and do other stuff with, unfortunately 
Maybe someone in the community should make something better than Inequalz in Asm(, is it possible?
