Well.. that worked. I didn't tried at first because the docs says it
can't be filled...

Can’t stop the signal.

Thanks Mike,
Actually, I don't want it to be filled, but the wedge did what I
wanted, so I'm sticking with it.

Arcs exist as an optimization to render really large circles and 
ellipses with high accuracy.
 An elliptical arc. Because it performs various optimizations, it
 can not be filled.
If you want to draw a filled, yet partial, circle, I believe you want to 
use Wedge.
Cheers,
Mike

There is no function axvlines -- there is vlines and axvline. If you
are making repeated calls to axvline you may be creating a whole bunch
of individual line objects and that will kill your performance. A
LineCollection will help here

Hello all
I'm having some troubles with Arcs in MPL. Using the following code:
 circ = Arc( (0,0), width=2, height=2, angle=0.0,
theta1=0.0, theta2=360.0, ec=None, fc=None)
 axes.add_patch(circ)
gives:
Traceback (most recent call last):
 File "pystereo22.py", line 524, in onPlotRose
 circ = Arc( (0,0), width=2, height=2, angle=0.0, theta1=0.0,
theta2=360.0, ec=None, fc='none')
 File "/usr/lib/python2.5/site-packages/matplotlib/patches.py", line
1043, in __init__
 fill = kwargs.pop('fill')
KeyError: 'fill'
It's working fine with Circle or Ellipse. I'm trying to use Arc
because I only want a half-circle.
Thanks all

Sorry, I'm not a ubuntu user, so I can't exactly tell how to do it. Of
course the devel package version mismatch the interpreter one, and
that's a problem for sure.
if you don't have a python2.5-dev or a python-all-dev IO think you
can't find an easy solution; since numpy does not yet support py2.6,
building mpl with 2.6 is still not a solution.

First run "apt-get build-dep python-matplotlib" to install the packages
that are needed to build matplotlib. Or, if you think you may want to
uninstall them later, see

I think I put a finger on what breaks the performance, thx to your
snippet of code.
I forgot to mention that I'm using some axvlines here and there (500 per
subplot).
it goes from slow to _unacceptably_ slow with the axvlines.
I'm using the axvlines to mark some events that I need to know about in
order to have an explanation of the variations of the curves.
any advice on what to use to replace those?

Hi all,
I guess I am doing something silly, but it is not obvious. Guess one of you
can help!!
I am using NumPy 1.3.0 and matplotlib 0.98.5.2
I am using the following to plot,
...
plt.rc('lines', linewidth=1.5)
...
sym = cycle([{'c':'b', 'ls':'-', 'marker':'o', 'mfc':'b', 'mec':'b',
'mew':'1.0'},
 {'c':'b', 'ls':'-', 'marker':'o', 'mfc':'w', 'mec':'b',
'mew':'1.0'},
 {'c':'g', 'ls':'-', 'marker':'s', 'mfc':'g', 'mec':'g',
'mew':'1.0'},
 {'c':'g', 'ls':'-', 'marker':'s', 'mfc':'w', 'mec':'g',
'mew':'1.0'}])
...
ax.plot(range(len(eles)), y, **sym.next())
plt.savefig('fig.eps')
plt.show()
The above fails even when I explicitly set lw in sym with the following,

Instead of starting with your cod,e start from scratch and see if you
can reproduce the problem. If not, figure out what is different and
work your way up. Here is some test code -- note that Eric Firing
made a contribution on the svn trunk that significantly speeds up this
use case:
import numpy as np
import matplotlib.pyplot as plt
fig = plt.figure()
Nplots = 5
Npoints = 5000
for i in range(Nplots):
 if i==0:
 ax = ax1 = fig.add_subplot(Nplots,1,i+1)
 else:
 ax = fig.add_subplot(Nplots,1,i+1, sharex=ax1)
 ax.plot(np.random.rand(Npoints))
ax.set_xlim(100, 200)
plt.show()

I'm trying to get approx 4k points plotted into 5 subplots which I would
like interactive (ie: ability to zoom/pan ...).
there's nothing special except that the subplots share axe x.
It gets some seconds (3 to 5) on a p4 dual core @ 3Ghz to pan/zoom. It
seems utterly slow to me: what do you think? normal "rate" or flawed code?
I tried using various backend, embedding it into qt4 ... nothing helped
much.
the code is quite fat atm (500 lines or so). I'll try to cut through the
code to get an example in a few lines if it's said my code is flawed and
the plotting rate should be way faster!

This means pngnq has quantized the original RGBA image with 8 bits per
channel to an image with a 256-color palette. I don't think Agg has any
support for rendering directly to a paletted image, so to achieve
similar results, you would have to do the quantization in a separate

A web application needs to be fast, right? According to its home page,
pngnq "is limited mostly to off-line uses rather than real time image
delivery". You could take a look at PIL to see if it has any fast
quantization algorithms, and pass your result to it as in the
to_numeric.py example (see also webapp_demo.py for how to avoid using
the pylab machinery for figure management). If not, you could always
implement some fast quantization algorithm in numpy:
http://en.wikipedia.org/wiki/Color_quantization
My guess is that if you always produce similar-looking images, you could
fix the palette off-line using whatever fancy algorithm you like, and
then the actual conversion could be done pretty fast, especially if you
can forgo dithering - perhaps for many types of charts it is not
necessary.

I see. Thanks for clarifying this. And yes, I think this should be fixed.
Hmm, it seems that somehow pil_to_array tries to make the image
upside-down by itself.
 x_str = im.tostring('raw',im.mode,0,-1)
However. I'm afraid that changing this behavior may not be ideal for
backward-compatibility.
I think one possible solution would be to simply deprecate the support
for PIL image in imshow, and let users explicitly use array-interface
via asarray function.
Is there any other idea?
I'll make this change unless someone come up with something.

Understood. And, yes, I guess you're quite right in this regard.
And I'll try to deprecate the current matlab-like interface in future
(at least in my axes_grid toolkit).

Hi all,
I had a few off-list conversation with Alan, and I'm also quite agree
with him for this issue.
Just to rephrase, I think the current subplot interface has (at least)
two issues.
 issue 1) the indexing convention is not that of python. The index
starts from 1, instead of 0. (eg "111")
 issue 2) It is not easy (actually impossible) to make an axes
spanning multiple cells.
While I think we need to keep the current interface at least for a
while, it would be better if we come up with some pythonic interface
that may eventually replace the current matlab-centric one.
So, how other developers and users think about this?
And here are a few options that has been suggested.
Option 1) use of "origin" keyword.
 ex) subplot(2, 2, 0, origin=0)
 Ryan is -1 for this and so am I.
 It also does not address the issue 2.
Option 2) Introduce a new command
 ex1) ax = fig.subplot2grid(shape=(3,3), loc=(0,0), rowspan=2, colspan=2)
 Instead of simple subplot(111), we may do something like
 ex2) ax = fig.subplot2grid((1,1), 0)
Option 3) introduce a new class for grid specification and modify
subplot to accept this.
 One idea I have is to use an array-like interface.
 ex1) ax = fig.subplot(grid_spec(3,3)[0:2,0:2])
 For subplot(111) equivalent,
 ex2) ax = fig.subplot(grid_spec(1,1)[0])
I, personally, want to reuse the convention in my axes_grid toolkit,
where it would be better if this grid specification(?) can be
expressed as a single argument. And I'm +1 for option 3 for this
reason. However, I'm afraid that option 3 is not expressive enough.
Of course, we should explore other solutions and any suggestions will
be welcomed.
So, how others think?
Regards,
-JJ

Hi mpl-users,
I have a web application in which I produce png files using
matplotlib. Unfortunately the files are quite big (up to ~300 kb). I
have however tried using the Linux tool pngnq to reduce the file size
with a factor ~3-4 with almost no degradation of the result. I
therefore wondered whether it is possible to setup matplotlib to do
something similar (from the source code the savefig method for png
files does not seem to use any keyword arguments). Here is the output
of the command pnginfo for the matplotlib output file and the pngnq
processed file:
0.0.0.0.0.0.20090517t00z.768.png...
 Image Width: 768 Image Length: 328
 Bitdepth (Bits/Sample): 8
 Channels (Samples/Pixel): 4
 Pixel depth (Pixel Depth): 32
 Colour Type (Photometric Interpretation): RGB with alpha channel
 Image filter: Single row per byte filter
 Interlacing: No interlacing
 Compression Scheme: Deflate method 8, 32k window
 Resolution: 5039, 5039 (pixels per meter)
 FillOrder: msb-to-lsb
 Byte Order: Network (Big Endian)
 Number of text strings: 0 of 0
 Offsets: 0, 0
0.0.0.0.0.0.20090517t00z.768-nq8.png...
 Image Width: 768 Image Length: 328
 Bitdepth (Bits/Sample): 8
 Channels (Samples/Pixel): 1
 Pixel depth (Pixel Depth): 8
 Colour Type (Photometric Interpretation): PALETTED COLOUR (256
colours, 0 transparent)
 Image filter: Single row per byte filter
 Interlacing: No interlacing
 Compression Scheme: Deflate method 8, 32k window
 Resolution: 0, 0 (unit unknown)
 FillOrder: msb-to-lsb
 Byte Order: Network (Big Endian)
 Number of text strings: 0 of 0
 Offsets: 0, 0
I am not using transparency for anything. For a web application a
reduction from 300 kb to 90 kb is really important so I hope you have
some good ideas. Otherwise I guess I will have to put in a call to
pngnq in my code (although I prefer to avoid calls to external
programs in the Python code when possible).
Best regards,
Jesper

My point is that that is not well defined,
since most of the OO API in Matplotlib is
Python centric, but the subplot definition
is an exception.
So I am suggesting that any new functions
certainly should not propagate this anomaly.

So, looking forward, keeping that anomaly isolated
will be important, so that changes do not need to
be made in additional locations. (Or so I claim...)

Hmm,
Is it working on your side from a bash shell as "ipython --pylab script
argument"
I couldn't make it work in this fashion. As I said whos list nothing :(
I am on Fedora 10 x86, Python 2.5.2, IPython 0.10.bzr.r1173
Without the pylab switch I see the interactive space with variables. I also
have plot imported from my script, however each time I have to call show()
to see the figure to be re-drawn.
To me, it seems one need to compromise: either to start ipython --pylab
first and call scripts using "run" magic command or like you suggested start
ipython with the script loaded and call show() after each plot command.
Please comment me if I am wrong...

Gökhan,
The "whos" command works for me.
Also, why can't you use "import pylab" and make your plots directly in ipython?
You can also use "from pylab import *" if you don't want to type pylab
every time.
