In principle, you should be able to draw dashed lines with the MacOSX backend.
Can you post a complete script that triggers this error?

Oh, and I'm using the Agg backend, I think, whatever is the default.

Thanks for the tips. I had seen one of those posts whilst googling around
for the bug, but discounted it because I'm not using an alpha value.
Here are links to one of the cookbook examples, and one of the files that I

Is this an ideas thread?
How about a "copy image to clipboard" button for the toolbar.

The dropbox link is broken (you need a public url).
What version of mpl and what backend are you using?
There was a similar problem which has now been fixed.
Try the work-around described in the thread below, and see if works.
http://www.nabble.com/problems-with-contourf---alpha-td22553269.html
When I do contourf plots in matplotlib, I get lines connecting the contour
levels. This doesn't only appear to be an artifact of my plotting
algorithms, it appears in this example from the matplotlib cookbook:

OK, thanks. I don't really know why it's failing, but I'm going to continue
trying to get other backends installed to test them.
I also now have independent reasons not to use the MacOSX backend:

Hi,
For a contour plot I use the option 'manual=True' in clabel
to set the location of the labels manually.
Before the plotting command I set some figure properties using
rcParams as explained on this site:

My Problem is, that the manual-o
Hello,
i'm new to the list.
i'm using matplotlib via the networkx graph package.
I wonder if there is a way i could draw a graph in a Tkinter canvas widget
of my application.
I.e. my Python application creates the Tkinter canvas and somehow passes it
as an
argument to a matplotlib draw function.

As I understand it the Mac backend uses the PyOS_ImputHook trick, which
means that no custom threading code is needed in IPython. Thus it should
"just work" without any threading flags in both IPython *and* regular
python. Just as an aside, wx is the only GUI toolkit that doesn't support
this "ne
On my system, this example appears to be working just fine. I even bumped
the number of data points from 1000 to 10,000. I'm on OS X 10.5.7 with:
matplotlib 0.98.5.2
PyQt 4.5.1 (GPL)
Qt 4.5 (LGPL)
Maybe try updating your PyQt installation?

The Mac OS backend is fairly new, and I don't believe any of the
backend-specific threading code that ipython requires has been
implemented for the OS-X backend. Just wanted to drop a note to say
"it's probably not you". But as a non-Mac user, I may be wrong, and I
hope to be corrected :)

Hi, I'm using ipython 0.9.1 with the svn version of matplotlib on 64 bit
python on mac os x 10.5.7.
I have only been able to get python-64 running with the MacOSX backend; all
of the others (wxpython, gtk, qt, tk) have failed for one reason or another.
I've tried ipython without any flags and
Yep, the same library (physical, on our network) fails depending only
the computer, thus on its own internal libraries called by GEOS.
By the way, I tried basemap with geos 3.0.4, and saw the "simplify()"
method working. That's funny!

I can reproduce the error with the svn version.
It seems that the problem is not SubplotHost specific, i.e., you have
same problem if you use mpl's original axes with twinx.
I think it has something to do with the axes sharing in general.
Preventing autoscale of xaxis suppress the error.

Here is one example :

Hi Brian,
I have also some layout problems with the Qt4 backend. The worst one is
a SegFault when adjusting the width.

Could you just try to add a second canvas to the layout?
