General background
----------------------------
I am using Mathematica to produce some graphs which I
then export in EPS format using the Display function. However, what is
rendered
in the file (viewed using, say, Adobe Illustrator, Adobe Photoshop or
Ghostscript)
is not what appears on the screen of my Windows 95 machine.

The problem is *illustrated* (I have tried to make the example as simple
as demonstrate the point)  by the following


p=ListPlot[
    {{0,1},{0.5,2},{1,1}},
    PlotRange->{{0,1},{0,2}},
     PlotStyle->PointSize[0.3],
    AxesOrigin->{-0.05,-0.1},
    AspectRatio->1/GoldenRatio,
    ImageSize->{3 72,3 72/GoldenRatio}
]

Three large discs (points) are visible in the display. The point at x=0 is
entirely
visible, the other two only partly visible ... explained, presumably by
something
to do with the bounding box. Furthermore, If the dimensions are changed so
that ImageSize->{5 72, 5 72/GoldenRatio}, then the x=0 point is also
truncated. Again, I presume that this is because the metric for the point
size is the width of the graph,
and the point extends past the left hand side of the labels on the y-axis.

Specific Problem
------------------------
However, while I can guess at what is going on here, the curious thing is
that
when I view the graph, after exporting it with Display["dlpplot.eps", p,
"EPS"] ,
the x=0 point is chopped in half so that nothing to the left of x=0 is
visible.
This makes some sense in terms of the stated PlotRange, but why the
difference
in what is visible in the notebook and in the exported file, and is there
any way
I can get the exported file to display what is in the notebook?
