You are right. I removed xpdf-utils from my machine and installed
poppler-utils instead (which on Ubuntu conflicts with xpdf-utils). The
result is now correct.
Thanks for your help!!

Apologies for all-too-brief reply the first time around. I am
more than rusty with matplot, but need to brush up again.

What you are wanting to do is not so straightforward and,
unfortunately, is not documented all in one place. I have=20
found a number of references to different bits-and-pieces
of the puzzle, and I include these here:

(in particular, the frame - x and y "axes" - does not have a=20
color setting and needs to be turned off, following which lines
can be drawn in its place with axhline and axvline)

I am sure more searching in the mail archives will yield=20
more gems!

Part of the issue is, I think, that these are all different types
of objects and therefore handled in different ways.

It would be really good to come up with a definitive example
and post it here.... when the question arises again, we can
just point back to this example (and possibly ask for it to be=20
included in further releases of the samples.zip from the=20
website).

Hi Derek,
I did
 setp(a2.get_xticklabels(), color=3D'w')
 setp(a2.get_yticklabels(), color=3D'w')
and this made the ticklabels readable, which is the main thing.
Ideally it would be nice to change the axes and tickmark colors but
it's not essential.
 setp(a2.get_xticks(), color=3D'w')
 setp(a2.get_yticks(), color=3D'w')
 setp(a2.get_axes(), edgecolor=3D'w')
don't work.
Many thanks, George Nurser.

These reports almost always turn out to be a problem with one of the external 
dependencies. I see no difference between the two results on my machine.

Hi All,
I have a problem with the output of the ps backend when I use the xpdf
distiller rather than ghostscript and try to save a figure from
imshow. When I run the script below I get a blue square with
ghostscript (as expected), but grey dots and lines with xpdf. With
non-image based plot commands I get normal (actually very nice)
results with xpdf. Any ideas? Thanks for any help!
Script:
=============
import scipy
import matplotlib
matplotlib.use('PS')
matplotlib.rc('ps', usedistiller='ghostscript')
#matplotlib.rc('ps', usedistiller='xpdf')
import pylab
a = scipy.ones((50,50))
pylab.imshow(a)
pylab.savefig('tplot.eps')
=============
Machine details:
xpdf version 3.02
GPL Ghostscript SVN PRE-RELEASE 8.61 (2007年08月02日)
scipy 0.5.2
python 2.5.1
matplotlib 0.90.1
x86_64 linux
Ubuntu Gutsy (beta) AMD64 version

Hi,
I feel that this should be simple, but I can't find anything on it.
How do I change the color of the axes/tickmarks/ticklabels?
I want to superpose a second plot onto a part of a pcolor plot that is
dark blue.
I can change the background color OK, but not that of the axes themselves.
Regards, George Nurser.
