I'm not sure what the cause may be, particularly since I can't reproduce it myself with matplotlib 0.99.1.1.
What backend are you using? Agg, Cairo and Wx all check out for me. The examples you point to don't look like Agg output to me... Do you have anything in your matplotlibrc?

Does this example work for you?

No, it doesn't. The green line is not being drawn.
After changing the style from 'g' to 'go' (marks instead of line) it
works flawlessly.
I asked the same question in the scikits mailing list, and was
redirected to a recent discussion:
http://old.nabble.com/Re%3A-Still-having-plotting-issue-with-latest svnscikits.timeseries-ts20941722.html#a20944512
At first I was sure that it is also my case, but after trying the
example you've mentioned I'm almost certain that it's not so simple.
So I'm still looking for a possible solution...
greetings,
Paweł

The examples were produced using savefig and PNG, but I've tried GTK
and Qt with Agg and Cairo - neither of them works.

Nothing but the backend...
I've just noticed that the green line shows sometimes when moving the plot.
Quick examples:
no move: http://img524.imageshack.us/img524/5696/61571712.png
slightly right (no change): http://img94.imageshack.us/img94/6722/44916983.png
more (green line appears): http://img27.imageshack.us/img27/522/91772530.png
even more (disappears behind the edge):

Hi Paweł, to repeat a point that may have been lost in Michael's first
email, some code that produces the problem will be greatly useful in
tracking down what's going on.

Hi Paweł, to repeat a point that may have been lost in Michael's first
email, some code that produces the problem will be greatly useful in
tracking down what's going on.
If I gather correctly, the masked_demo.py example in the matplotlib source is sufficient to reproduce the bug. Unfortunately, I can't reproduce it here with 0.99.1.1 or SVN HEAD, so there's some environmental difference about Pawel's system -- of course I'm at a loss as to what it might be.
Are you sure you're running 0.99.1.1? Earlier versions have exhibited this class of bug, but I thought they were all squashed by now. What does the following give for you?
> python
Python 2.5.2 (r252:60911, May 7 2008, 12:40:32)
[GCC 3.4.6 20060404 (Red Hat 3.4.6-9)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import matplotlib
>>> matplotlib.__version__
'0.99.1.1'
Cheers,
Mike

Yes, exactly.

I suppose it may be somehow Gentoo-related problem - unfortunately I
only have Gentoo boxes here, so I cannot check another OS, but the
same problem occurs on a second machine.
Furthermore I asked a friend with a Gentoo system and he confirmed
this behaviour, so in the meantime I filed a Gentoo bug:
http://bugs.gentoo.org/show_bug.cgi?id=301062
Maybe anyone here is also using Gentoo and can check it?
Are you sure you're running 0.99.1.1?
Yes, 0.99.1.1 with Python 2.6.4

Can you try building matplotlib 0.99.1.1 from the tarball, rather than the gentoo package? That would help to rule out any of the gentoo-specific changes. Nothing in the portage leaps out at me as problematic, but we should rule that out.

I just tested 0.99.1.2 (no 0.99.1.1 tarball seems available on SF) and
svn trunk and found no trouble with either on Ubuntu Karmic amd64.

I was trying to avoid this, because I didn't want to mess up with my

simultaneously...

now it works flawlessly. So it is certainly a Gentoo bug.
Thanks!

I can't replicate here on either of my AMD64 Gentoo system (with
Gentoo's 0.99.1.1 matplotlib package). I should note that one is up
to date with Portage (synced Monday) and the other is about 6 weeks
out of date.
With both, I see all 3 lines, correctly masked, unless I'm supposed to
be looking for something else....?
While it might be a Gentoo bug, I don't think it's necessarily in the
matplotlib package, but rather in the underlying dependencies.
Anybody have any clue what to look at from here? Have you tried
blowing away the Gentoo install of matplotlib completely and trying a
new one?
