Assuming you're using the Image tool, look at Options->Set Background
Color. If you are using AutoAxes, to change the axis colors, do
Image->Options->AutoAxis->Annotation Colors and look at the bottom of the
dialog.
If you're using Camera/Display/AutoAxes, the background color is an option
for Camera, and the AutoAxes colors are options for AutoAxes.

This I have done. I guess my main problem is that the background is always
black which is not good for printing on white paper. There should be some
command for switching the background to white, but I didn't find it in the
reference manual.
Thanks, Nicolas
P.S.: Another problem is that the pictures are stored as bitmaps (as much
as I can see). Of course, this is very much overhead for a simple
xy-graph, see the example below. Is there a way to make better use of
postscript here?

Look at it e.g. with
dx -script
data = Import("image-data-1d.dx");
data = Options(data, "mark", "circle");
xyplot = Plot(data);
camera = AutoCamera(xyplot);
image = Render (xyplot, camera);
Display (image);
Write it with:
WriteImage(image,"image-data-1d.dx", "ps");
