I tried that, but there doesn't seem to be any good way to control the
size of the symbol that you get out. You can use xyouts to get the
size of a character, and the plotting routine sets the plotted size of
the character to be "about" the size of a character. But, there
doesn't seem to be a way to control accurately the size of the symbol.

I thought of what will probably be a better solution. I'll use plot
with /NODATA to set up the axes and data space, then get the number of
pixels in the display area and the data range, then create an array
as big as the display area, fill it with my little boxes of different
sizes and colors, and then tv it once.
