Axis direction change

[ysnegirev]

Hello! Suppose, I have a Qwt Plot. And suppose, I want the origin (the point, relative to which all drawing calculations are actually implemented) to be, say, at the top right corner of the plot. Is there any way to do this?
I'll try to include a picture, displaying what I want to implement.
p.s. don't mind, that lengths of distances are not equal on the picture. In real life, they must be.
