Uh, well, I get identical results in my object graphics
XPLOT program (download the latest, there have been some
changes in most of these object program examples in the
past week or so) as I do in the direct graphics case.
Perhaps you are scaling the axes incorrectly. That is
*easy* to do in object graphics.

   XPlot, x, sin(x), xrange=[0,8.5], Exact=[1,0]

The program is available here:

   http://www.dfanning.com/programs/xplot.pro

Note that the zip files in this directory have NOT 
yet been updated with the program changes from the 
past two weeks. Maybe later this week. :-)

Cheers,

David
