The little test routine used the Vector kwd. That is when the problem
of the black polygons appears.

On my real data it worked, almost (it is more complex than the flat
figure I submitted). IDL generated the plot OK, but when I exported
into eps, the polygon lines were not of constant thickness. Some were
thicker than others, and some non-existent.
Furhtermore, I'm a bit unhappy with the tick-marks in eps output.
They are not parallel. I suspect it is due to the drawing commands
were geared to a pixelated device and being literally translated to
the vector output). I'll try to come up with a little test routine,
but it will take time, as I am not versed in OG.
I am also re-considering my insistance on eps. After all, all I need
is file that can be included into a print version of a document.
Thus, I need a high resolution output file. So I'll try to figure
that one out. I've seen several kwds dealing with dimensions and
pixels.
The reason I prefer eps, is that I can easily include it into latex
documents, and also convert it after the fact to any format I want
(tiff, jpeg, png, bmp, etc) using ghostscript. This last format (etc)
is a proprietary format with which I will achieve world domination of
picture and figure formats :-)
Thanks to all so far.
