I downloaded keypress_demo.py from the matplotlib website
runs as follows
./keypress_demo.py (then typed letter 'c')
Exception in Tkinter callback

now you are making me think something is wrong with my build, but
this is an out of the box laptop, 10.5, numpy 1.2.1, zlib-1.2.3,
freetype-2.3.7, libpng-1.2.33, then build matplotlib-0.98.5

note: i backed down to 0.98.3, it works fine

Eggs are an abomination -- the person who named the installer
"easy_install" should have their license revoked. I think we may
distributing them because they are simply broken in too many ways.
This recurring problem -- where the easy_install goes looking on pypi
for an egg even though you are pointing at one locally on the file
system, is simply ridiculous.
Chris Barker suggests renaming the egg to matplotlib-0.98.5-py2.5.egg.
 Try that, and please let me know. Thanks for the testing.

Please run the following commands after cleaning the previous installs
and reinstalling the mpkg file::
 ls
 python -c 'import matplotlib; print matplotlib.__file__'
 python -c 'import matplotlib; print matplotlib.__version__'
 python -c 'import pylab'
The ls is important because sometimes a person has a directory named
'matplotlib' in their local path, and this is getting picked rather
than the installed matplotlib which contains the pylab module.

Thanks for the reply. I will be taking a look at the code, and if I come up
with anything useful, I can post it. (It might be nice if eventually there
were extra styles, e.g. "-|>", "<|-|>" for single lines with solid
arrowheads).

Mauro: Say you create a cylindrical basemap with lon_0=180. The 
longitudinal extent of the map will be lon=0 to lon=360. If you then 
plot a point with a longitude of -60, it will be off the map to the left 
(similar to what your example plot shows). The solution is to 
renormalize the longitudes of the points your are plotting to be within 
0 and 360 (by adding 360 if the longitude is negative).

Dear Jeff & ALL,
When trying to plot a set of points in Basemap using an
Equirectangular projection centered on a longitude different from the
default (using the parameter lon_0 to generate a map centered on the
desired longitude), I end up with a stange plot like the one attached
to this message (ie., all the points are plotted "over the edge of the
world"). Has Basemap been taught about the sphericity of the Earth?
(just a joke!)
N.B. This happens no matter if I call ax.cla() (where ax is an
instance of figure.axes) and reload all the dataset after changing the
longitude.
Any hints?

(a) As of now, there is no arrowclass that meets your need. The arrow
is implemented as a single path, and it IS still possible to draw a
line+a triangle. But, the artist only has a single "fill" mode and it
is impossible to fill only a part of the path. It may be relatively
easy to support. I'll take a look into it.
(b) The FancyArrowPatch was very recently introduced and it's argument
is not consistent with previous ones (Arrow,FancyArrow, YAArrow).
Unlike other classes, FancyArrowPatch itself does not know how to draw
an arrow. It delegates it to ArrowStyle. So, If you want to use
FancyArrowPatch, "headwidth" should be given to ArrowStyle not to
FancyArrowPatch itself. I agree this can be a bit confusing, but all
the arrow-related parameters should be given to the style class.
Take a look at "annotation_demo2.py" and see how it specifies the
arrowstyle (and also connectionstyle). The 'arrowprops' parameter in
the annotate function is mostly consumed by FancyArrowPatch class.

Hi Jeff,
Thanks very much for this bit of code that you sent me. I got some graph
paper out and plotted all of the axes in your code and it finally all made
sense.

The problem is caused by outdated *.pyc files. The solution is
sudo python -c 'import matplotlib'

Great. Is there a way to draw filled in arrow heads?
I'm thinking of arrows like those made by graphviz, such as,
http://www.graphviz.org/Gallery/directed/fsm.html
The closest I can seem to get is like this,
c = matplotlib.patches.FancyArrowPatch((0.2, 0.2), (0.5, 0.5),
arrowstyle="simple", linewidth=0.1, fc='k',mutation_scale=20.)
(a) I don't know if this is possible if the whole arrow is implemented as a
single polygon (i.e. to draw line with a triangle head), and (b) I'm a bit
confused about the kwargs to the different things like axes.arrow,
FancyArrowPatch, ArrowStyle, etc. (for example, arrow takes 'headwidth',
but FancyArrowPatch does not.).
Thanks a lot,
Ken

After sleeping on this overnight, I think the answer here is clear.
figimage is meant to be a pixel dump, so we should just treat a pixel
as a dot. When dpi is increased, the number of dots on the canvas
increases so the figimage should look smaller. I added your patch and
support for magnification to figimage -- the output looks right for
PNG, PDF and EPS -- svg still not. I haven't had a chance to look but
perhaps SVG does not utilize the magnification param. I'll check into
this later.

Oddly, this hasn't been answered, so I will, but as I understand it 
from previous list conversations: no, there are no plans to bring back 
3D capabilities in MPL.
Take a look at https://svn.enthought.com/enthought/wiki/MayaVi for 
your 3D plotting needs, it's quite well supported by Enthought and can 
be used in tandem with MPL in the same ipython session.

This is a correct way indeed.
I believe that you considered it as a plain line because the arrow
head is too small.
You need to adjust the mutation_scale parameter. Try
c = matplotlib.patches.FancyArrowPatch((0.2, 0.2), (0.5, 0.5),
arrowstyle="->", mutation_scale=20.)
Maybe the defaults need to be changed.

This method is not intended to be called directly by user. Currently,
the first argument of the __call__ method should be a path with
path.codes != None. It can be a straight line, but still you have to
explicitly set its codes. Futhemore, some arrow classes (Simple, Fancy
and Wedge) only accept a single segment of cubic bezier line.
FancyArrowPatch internally uses ConnectionStyle class to create
bezier cuve. Take a look if you're interested in.
