DX is not a vector renderer. It is a pixel renderer only. There is no
anti-aliasing feature built-in to DX either. With such a small small
arena, it is going to be difficult to get the quality you desire. If
you're data viz does not require much of a large arena, you can up
the small arena at the cost of losing some large arena by setting
some environment variables (look at the current HTML docs for the
appropriate setting.) The other option is to get the VIS Inc version
of OpenDX for Windows and run it instead. How much physical memory do
you have installed?

Dear DXplorers,
I am trying to produce nice hardcopies of my visualisations, but I
have 2 vexing problems.
First, I keep getting out-of-memory errors (large arena) when I
write EPS files. (The large arena is limited to 24 Mb, apparently
thanks to cygwin.) I don't see why this should happen when writing
EPS files of a few hundred kb (it seldom happened when I wrote MIFF
files of 16-frame sequences using the same net).
I get small-arena out-of-memory errors when I write TIFF files of >
2 Mb, so that avenue is out.
Second, neither file format yields prints with non-aliased vector
glyphs: I still see the staircase effect. I understand that I can't
get enough definition with TIFF if output file size is limited to 2
Mb, but why do I get this with EPS? My 11-year-old DOS CAD program
produces EPS files with no aliasing of diagonal lines, so I had
similar expectations of DX.
I have set 'Allow Rendering' and specified 300 DPI for the EPS
files. This currently restricts me to images of about 2" square, to
avoid the memory problems; this, too, is unacceptable.
Thanks in advance,
