If you are actually using a NASA logo, rather than what
you showed us here, I would guess that some colors get loaded
to show that image. A simple fix would just be to load a
color table first (this should probably be done *anyway*
if colors are important to you, and when are they NOT?):

LoadCT, 0, /Silent

When I find a real job, we call ALL celebrate! :-)

Wow Dave, thanks a lot.
Your suggestions (as expected) worked like a charm. I really
appreciate them.

It is much better, as you suggest, to first set up the plots, and them
draw the frames and margins.

The NASA logo and others are created outside of the margin (the
screen) because I'm not interested in viewing them on the screen, but
when you create the PS output, they do appear as "footnotes" in the
paper. This is important when creating a printed report, where I do
want the NASA logo to appear, and my name. I should also add a "thanks
to Dave Fanning" in that section :)

Another situation is still freaking me out: after I run the code, the
SECOND time the direct graphics appear yellow! (the first ones are
white). I have nothing against that color, but I did not request it!
This happens to me all the time, when I change the device and set it
back. My device is "X".

I will look into the yellow problem, but the code now works as
expected.

Many thanks, I owe you a beer (after all your suggestions, maybe I
should get a keg :)

WHOOPS! That NOERASE was an experiment and wasn't suppose
to be there. Sorry. The line should read:

FOR J = 0,5 DO PLOT, FINDGEN(10)

Note that this code produces decent PostScript output,
except that your NASA logo and title are inside of
your avowed 5% margin.

Cheers,

This gets you closer to where you want to be, although you
are still drawing the logo off the page! :-)

Humm. Well, there is a LOT going wrong in this code. :-)

The main thing is that you are drawing graphics in DATA
coordinates, but you haven't established a DATA coordinate
system in the code. So it's using the *last* one that did
get established, which could be anything at all. That's
why you can't reproduce anything.

It looks to me like you want to draw graphics in a NORMAL
(normalized) coordinate system. If so, you will need to set
a NORMAL keyword on all your PLOTS and XYOUTS commands.

I would also draw the plots *first*, then put all the
annotation on the plots. It is the NOERASE keyword on
your PLOT commands that I think is really screwing you
up here. I see why you want to do it, since all your
annotation disappears when the first plot is drawn, but
it plays absolute havoc with your data coordinate system.

Cheers,

David
