matplotlib-devel Mailing List for matplotlib

Hi Tom,
This is the right place to ask.
I'm working on putting some documentation together and I'll also look
into getting Text3D supported again. I hope to push things to svn next
weekend...
Regards,
Reinier

Hello All,
I have attached a patch that updates backend_fltkagg.py to use the new
Transform APIs for 0.98.0 (
http://matplotlib.sourceforge.net/api/api_changes.html#notes-about-the-transforms-refactoring).
Without these changes, trying to use FLTKAgg causes a crash with a very
cryptic error.
Thanks for all your work on matplotlib!

I've done some digging on this -- the segfault is happening in
_png.cpp on the line
 png_write_info(png_ptr, info_ptr);
and the error is
 Unhandled exception at 0x7c91b1fa in python.exe: 0xC0000005: Access
violation writing location 0x00000010.
when I paste this part of the message into google "python.exe:
0xC0000005: Access violation writing location 0x00000010" I find all
kinds of matches. Eg, this page
 http://stackoverflow.com/questions/391917/jpeg-support-with-ijg-getting-access-violation
suggests that there could be a problem in trying to pass FILE *
pointers to shared libraries. It seems we've done what is necessary
to compile these statically, but I'm just throwing this out there in
case it stimulates some ideas. I'm stuck so far in trying to fix
this.

I can't say that I have them. Petr, you can use 98.5.3 binaries found
here, "http://drop.io/tvuqe3o". Just keep in mind that png operations
will fail.

Hi all,
The time for the Scipy'09 conference is rapidly approaching, and we
would like to both announce the plan for tutorials and solicit
feedback from everyone on topics of interest.
Broadly speaking, the plan is something along the lines of what we
had last year: one continuous 2-day tutorial aimed at introductory
users, starting from the very basics, and in parallel a set of
'advanced' tutorials, consisting of a series of 2-hour sessions on
specific topics.
We will request that the presenters for the advanced tutorials keep
the 'tutorial' word very much in mind, so that the sessions really
contain hands-on learning work and not simply a 2-hour long slide
presentation. We will thus require that all the tutorials will be
based on tools that the attendees can install at least 2 weeks in
advance on all platforms (no "I released it last night" software).
With that in mind, we'd like feedback from all of you on possible
topics for the advanced tutorials. We have space for 8 slots total,
and here are in no particular order some possible topics. At this
point there are no guarantees yet that we can get presentations for
these, but we'd like to establish a first list of preferred topics to
try and secure the presentations as soon as possible.
This is simply a list of candiate topics that various people have
informally suggested so far:
- Mayavi/TVTK
- Advanced topics in matplotlib
- Statistics with Scipy
- The TimeSeries scikit
- Designing scientific interfaces with Traits
- Advanced numpy
- Sparse Linear Algebra with Scipy
- Structured and record arrays in numpy
- Cython
- Sage - general tutorial
- Sage - specific topics, suggestions welcome
- Using GPUs with PyCUDA
- Testing strategies for scientific codes
- Parallel processing and mpi4py
- Graph theory with Networkx
- Design patterns for efficient iterator-based scientific codes.
- Symbolic computing with sympy
We'd like to hear from any ideas on other possible topics of interest,
and we'll then run a doodle poll to gather quantitative feedback with
the final list of candidates.
Many thanks,
f

Hi-
I'm sorry if this should be in mpl-users; since mplot3d is a work
in progress and not documented I thought the question might
better fit mpl-devel.
I'm trying to migrate some old code that used matplotlib.axes3d to
use mpl_toolkits.mplot3d.axes3d. For an axes3d instance ax, it
used the ax.text3D method to place labels on the 3-D axes. Is
there a counterpart for mplot3d.axes3d? The only similar method I see
there is text(), which only takes an (x, y) position instead of
an (x,y,z) position.
Thanks,
Tom
