matplotlib-devel Mailing List for matplotlib

Thanks for passing this along, Nicolas.
Agg is some serious ninja-voodoo... Whenever looking through it to 
explore something new, I move from utter confusion to complete amazement 
at how all kinds of difficult problems are solved in an ingenious and 
ultimately extremely flexible way. And I think it's fair to say that 
matplotlib would not have achieved the level of overall raster quality 
it has without Agg under the hood.

Hi,
Unless I'm wrong in release 1.3.1, FigureCanvasGTK3Cairo does not define
blit(), neither in parents FigureCanvasCairo nor in FigureCanvasGTK3.
However from FigureCanvasBase it inherits of supports_blit = True.
Therefore when using widgets such as SpanSelector, the test "if
self.useblit" is true and cause a call to copy_from_bbox which is
undefined (actually copy_from_bbox is defined in FigureCanvasAgg).
Setting supports_blit = False on Canvas instantiation seems to fix the
issue for now. Is my understanding correct ?

Hi,
Very sorry to miss this one - I'm in Cuba at the moment - if Google
doesn't block hangouts, then there would not be enough bandwidth.
Sorry not to get to setting up buildbot testing. Paul - do you have
time for that?
Cheers,
Matthew

I also got this initial experimental demo working on the Sage cell server:

Following a very helpful conversation with Michael this morning in the 
dev hangout, I got this working with the current master (of matplotlib 
and ipython). The refactoring made the code much better; thanks!
I updated the pull request at 
https://github.com/matplotlib/matplotlib/pull/2524
To test this, run IPython (master branch, to get the comm commits), and 
put this in a cell: 
https://github.com/matplotlib/matplotlib/pull/2524#issuecomment-28539813
Then you can execute something like:
from matplotlib.figure import Figure
import numpy as np
fig = Figure()
a = fig.add_subplot(111)
t = np.arange(0.0, 3.0, 0.01)
s = np.sin(2 * np.pi * t)
a.plot(t, s)
CommFigure(fig)
and get a live figure in the IPython notebook that uses the comm 
messaging infrastructure.
Michael---do you have time to take it from here?
Thanks,
Jason

Hello
I would really like to participate but at work the hangout connection
is strictly forbidden.
It would be nice if you could discuss the possibility of making a
feature branch to do the "rework of all the backends" to include
* Separation of toolbar and navigation
* Reconfigurable toolbar
* Multifigure window (notebook or other)
* Removal of pyplot dependencies from the backends.
Every one of this items, needs to modify all the backends.
I offer myself to do the work on Gtk3, Gtk, and Tk
Thanks

I was just thinking about spending a bit of time on the matplotlib 
comm-based backend. I'd like to join for at least a little bit:

Hi folks,
forgive me for the x-post to a few lists and the semi off-topic nature of
this post, but I think it's worth mentioning this to our broader community.
 To keep the SNR of each list high, I'd prefer any replies to happen on the
numfocus list.
Yesterday, during an event at the White House OSTP, an announcement was
made about a 5-year, 37ドル.8M initative funded by the Moore and Sloan
foundations to create a collaboration between UC Berkeley, the University
of Washington and NYU on Data Science environments:
- Press release:
http://www.moore.org/newsroom/press-releases/2013/11/12/%20bold_new_partnership_launches_to_harness_potential_of_data_scientists_and_big_data
- Project description:
http://www.moore.org/programs/science/data-driven-discovery/data-science-environments
We worked in private on this for a year, so it's great to be able to
finally engage the community in an open fashion. I've provided some
additional detail in my blog:
http://blog.fperez.org/2013/11/an-ambitious-experiment-in-data-science.html
At Berkeley, we are using this as an opportunity to create the new Berkeley
Institute for Data Science (BIDS):
http://newscenter.berkeley.edu/2013/11/13/new-data-science-institute-to-help-scholars-harness-big-data
and from the very start, open source and the scientific Python ecosystem
have been at the center of our thinking. In the team of co-PIs we have, in
addition to me, a bunch of Python supporters:
- Josh Bloom leads our Python bootcamps and graduate seminar)
- Cathryn Carson founded the DLab (dlab.berkeley.edu), which runs
python.berkeley.edu.
- Philip Stark: Stats Chair, teaches reproducible research with Python
tools.
- Kimmen Sjolander: comp. biologist whose tools are all open source Python.
- Mike Franklin and Ion Stoica: co-directors of AMPLab, whose Spark
framework has Python support.
- Dave Culler: chair of CS, which now uses Python for its undergraduate
intro courses.
We will be working very hard to basically make BIDS "a place for people
like us" (and by that I mean open source scientific computing, not just
Python: Juila, R, etc. are equally welcome). This is a community that has a
significant portion of academic scientists who struggle with all the issues
I list in my post, and solving that problem is an explicit goal of this
initiative (in fact, it was the key point identified by the foundations
when they announced the competition for this grant).
Beyond that, we want to create a space where the best of academia, the
power of a university like Berkeley, and the best of our open source
communities, can come together. We are just barely getting off the ground,
deep in more mundane issues like building renovations, but over the next
few months we'll be clarifying our scientific programs, starting to have
open positions, etc.
Very importantly, I want to thank everyone who, for the last decade+, has
been working like mad to make all of this possible. It's absolutely clear
to me that the often unrewarded work of many of you was essential in this
process, shaping the very existence of "data science" and the recognition
that it should be done in an open, collaborative, reproducible fashion.
Consider this event an important victory along the way, and hopefully a
starting point for much more work in slightly better conditions.
Here are some additional resources for anyone interested:

No, Paul, I haven't really had the time to dig into it myself. I would
also appreciate it very much if anyone could provide an explanation, how
this works and whether it can be used like this.

Eduard,
Did you make any progress on this? I'm trying to do the same thing and it's
skipping my tests entirely.

Hello everybody
Last week there was some discussion about splitting the toolbar into
two different entities
Navigation and Toolbar
PR https://github.com/matplotlib/matplotlib/pull/1849
and
PR https://github.com/matplotlib/matplotlib/pull/2557
Does anybody has any new thoughts or propositions?
Thanks
Federico
