[Matplotlib-users] 4D Scatter Plot
Hello, I am interested in producing a 4 dimensional plot to represent some data. I picture this as looking like a normal 3d scatter plot with datapoints varying in a color scale which depends on a fourth column of data. Could anyone help me with this- I have searched google and the matplotlib website and have only found some documentation for a MatLab solution bywhich I am not interested. Thank you kindly! -Francois -- All of the data generated in your IT infrastructure is seriously valuable. Why?

[Matplotlib-users] Exceptions on Some Demos
I've used Add/Remove Software to install
python-matplotlib-0.98.5.2-2.fc10(i386) and
python-matplotlib-tk-0.98.5.2-2.fc10(i386) on my fedora 10 box, plus 11
dependencies, including Tkinter. Some matplotlib examples, eg pylab_examples
Examples/arctest.py works nicely, but many do not as presented.
Example api Examples/barchart_demo raises the following traceback when
executed as-is:
[jon@einstein matplotlib-examples]$ ./barchart.py
Traceback (most recent call last):
File "./barchart.py", line 18, in
error_kw=dict(elinewidth=6, ecolor='pink'))
File "/usr/lib/python2.5/site-packages/matplotlib/pyplot.py", line 1656,
in bar
ret = gca().bar(*args, **kwargs)
File "/usr/lib/python2.5/site-packages/matplotlib/axes.py", line 4075, in
bar
r.update(kwargs)
File "/usr/lib/python2.5/site-packages/matplotlib/artist.py", line 548, in
update
raise AttributeError('Unknown property %s'%k)
AttributeError: Unknown property error_kw
(I've copied the example code into script barchart.py, and run it from
there.)
The problem line is:
rects1 = plt.bar(ind, menMeans, width,
color='r',
yerr=menStd,
error_kw=dict(elinewidth=6, ecolor='pink'))
If I replace this with:
rects1 = plt.bar(ind, menMeans, width,
color='r',
yerr=menStd)
and do the same thing for the rects2 statement, the demonstration then
presents the bar chart.
The problem seems to lie somewhere with the error_kw arg being passed to
method plt.bar. Is there something else I need to do to get the provided
examples to work as coded?
TIA,
Jon

[Matplotlib-users] PyCon DE 2011 - Call for Proposals extended to July 15, 2011
PyCon DE 2011 - Deadline for Proposals extended to July 15, 2011 The deadline for talk proposals is extended to July 15, 2011. You would like to talk about your Python project to the German-speaking Python community? Just submit your proposal within the next two weeks: http://de.pycon.org/2011/speaker/ About PyCon DE 2011 --- The first PyCon DE will be held October 4-9, 2011 in Leipzig, Germany. The conference language will be German. Talks in English are possible. Please contact us for details. The call for proposals is now open. Please submit your talk by June 30, 2011 online. There are two types of talks: standard talks (20 minutes + 5 minutes Q&A) and long talks (45 minutes + 10 minutes Q&A). More details about the call can be found on the PyCon DE website: http://de.pycon.org/2011/Call_for_Papers/ Since the conference language will be German, the call is in German too. PyCon DE 2011 - Neuer Einsendeschluss für Vortragsvorschläge 15.07.2011 === Noch bis zum 15.7.2011 kann jeder, der sich für Python interessiert, einen Vortragsvorschlag für die PyCon DE 2011 einreichen. Es gibt nur zwei Bedingungen: das Thema sollte interessant sein und etwas mit Python zu tun haben.

Mögliche Themen sind zum Beispiel: * Webanwendungen mit Python * Contentmanagement mit Python * Datenbankanwendungen mit Python * Testen mit Python * Systemintegration mit Python * Python für große Systeme * Python im Unternehmensumfeld * Pythonimplementierungen (Jython, IronPython, PyPy, Unladen Swallow und andere) * Python als erste Programmiersprache * Grafische Nutzerschnittstellen (GUIs) * Parallele Programmierung mit Python * Python im wissenschaftlichen Bereich (Bioinformatik, Numerik, Visualisierung und anderes) * Embedded Python * Marketing für Python * Python, Open Source und Entwickler-Gemeinschaft * Zukünftige Entwicklungen * mehr ... Ihr Themenbereich ist nicht aufgelistet, wäre aber aus Ihrer Sicht für die PyCon DE interessant? Kein Problem. Reichen Sie Ihren Vortragsvorschlag einfach ein. Auch wir können nicht alle Anwendungsbereiche von Python überschauen. Vortragstage sind vom 5. bis 7. Oktober 2011. Es gibt zwei Vortragsformate: * Standard-Vortrag -- 20 Minuten Vortrag + 5 Minuten Diskussion * Lang-Vortrag -- 45 Minuten Vortrag + 10 Minuten Diskussion Die Vortragszeit wird strikt eingehalten. Bitte testen Sie die Länge Ihres Vortrags. Lassen Sie gegebenenfalls ein paar Folien weg. Die Vortragsprache ist Deutsch. In begründeten Ausnahmefällen können Vorträge auch auf Englisch gehalten werden. Bitte fragen Sie uns dazu. Bitte reichen Sie Ihren Vortrag auf der Konferenz-Webseite http://de.pycon.org bis zum 15.07.2011 ein. Wir entscheiden bis zum 31. Juli 2011 über die Annahme des Vortrags. -- All of the data generated in your IT infrastructure is seriously valuable. Why?

Jon,
The examples on the website are for version 1.0.1, which is a couple of
years older than version 0.98. Many examples utilizes new features that
have since been added to matplotlib.
Also, as a side note, Fedora 10 has stopped receiving updates of any kind
about 2 years ago. This also means security updates.

Thanks, Ben. I'll install 1.0.1. I'm aware of the situation about Fedora 10.
