I've never done object graphics, but with the basic PLOT function, just specify
the axis range (e.g., !X.RANGE = [xmin,xmax]) with the "minimum" greater than
the "maximum".

Example:

x = findgen(500)/50.
y = 3.5*sin(x)*x
!y.range=[30.,-20.]
plot,x,y

Is there a similar mechanism for object graphics? If so, you might give it a
try.
