Odd. I'll email you, this may need more detail than is effective for
the newsgroup.

Well, there doesn't appear to be any restrictions
from either PS_START or PSCONFIG. The results come
back with a window that is 10 inches by 10 inches.
Of course, you can't put a 10x10 inch window on
a normal "page" of PostScript output, so you need
to tell me what you are doing here. Are you plotting
this on some plotter or something? What makes you
think there is a "problem"?
Cheers,
David

OK, well, this works for me, too, then:
x = indgen(101)
y = cgDemoData(1)
errors = randomu(-3L, 101)*4
cgPlot, x, y
oploterror, x, y, errors, errcolor=cgcolor('black')

PS_END spawns the "convert" command to check for its presence.
If it can't find it, I presume it is because the "convert" command
is not on the path of the shell running IDL. Macintosh computers
are a bit of a mystery to me, so if you have a suggestion for how
I can solve this problem, I'm all ears.
Someone suggested a configuration parameter that could locate
ImageMagick. Maybe I'll look into that a bit.

Humm. That might be a PSConfig limitation. I'll look into it
and get back to you.

David

oploterror is a wrapper for oploterr from the NASA astronomy IDL
library. I'll try what you wrote when I get home.
More questions! I have ImageMagick installed. When I run convert -
version from my normal bash command line, it works fine, but PS_END
can't find it. Help?
Also, PS_START seems to be ignoring my xsize and ysize keywords; the
following gives me an 8.5x11 ps output:
IDL> ps_start, /nomatch, xsize=10., ysize=10., /
inches,filename=filts[filt]+'_'+dn+'.ps'

Sorry, I took an hour to take a walk in the sunshine. First
time I've been out of my cell for several months. :-)
Well, first of all, OPLOTERR is brain dead. So,
I can't do much about that. (I assume this is what
you mean by OPLOTERROR?)
But this works:
!P.Background = cgColor('white', 254)
!P.Color = cgColor('black', 253)
x = indgen(101)
y = cgDemoData(1)
errors = randomu(-3L, 101)*4
cgPlot, x, y
oploterr, x, y, errors
Is that what you mean?
Cheers,
David

Can you put in a /SILENT keyword for PS_END?
