matplotlib-users Mailing List for matplotlib

Does this get you close?  It seems what your trying to do might be a bit 
ambiguous, but I understand the problem with the y-axis when there are 
lots of subplots.

Maybe it would be better to change the y-ticker to make fewer ticks or 
the labels to be smaller.

-Chip

from matplotlib import pyplot as plt

t = [0,1]
y=[0,1]

fig = plt.figure()

plt.axes([0.1,0.1,0.8,0.8], frameon=True, axisbg='w')
ax = fig.add_subplot(211)
plt.setp(ax.get_yticklabels(), visible=False)
plt.plot(t,y)
ax = fig.add_subplot(212)
plt.setp(ax.get_yticklabels(), visible=False)
plt.plot(t,y)
plt.show()

Hi all,

Two months ago, I made an announcement regarding a little open-source 
project of mine, PyQtShell -- that is a module providing embeddable 
console widgets for your PyQt applications (interactive Python shell, 
workspace, working directory browser, editor, ...) as well as "Pydee", a 
PYthon Development EnvironmEnt based on these widgets (which could 
become an interesting alternative to IDLE for example).

Pydee features have been greatly enhanced these last weeks, and a lot of 
bugs were fixed thanks to Christopher Brown (thank you again Christopher 
for your bug reports/feature requests which are always very detailed and 
constructive).

I recently (a few minutes ago actually..) added an interesting feature 
in Pydee v0.3.0: matplotlib integration (i.e. matplotlib figures can be 
docked inside Pydee which is quite convenient).
See this screenshot for example:
http://source.pythonxy.com/PyQtShell/screenshots/ss3.png

Other screenshots and informations:
http://pypi.python.org/pypi/PyQtShell/
http://code.google.com/p/pyqtshell/

As some of you may have noticed, Pydee is intended to be a mini-MATLAB 
environment -- that being said, it still at an early stage of development.

Cheers,
Pierre

Fixed on the trunk; the test case is examples/api/joinstyle.py. Thanks
for your report!

There's the kicker -- I believe (and I haven't been heavily involved in 
this, so correct me if I'm wrong) the due date for applications is this 
Friday.  I don't have time to do that either.  MPL tagged along with the 
PSF last year and it worked great (very low administrative overhead for 
us mentors), until it fell through for unrelated reasons.

Cheers,
Mike

I spoke with the SoC coordinator about this last year and was told
they would prefer us to stay under the PSF umbrella.  This year they
plan to sponsor fewer mentoring organizations, I believe (so less
chance we would get accepted).  Finally, the deadline for submitting
an application to be a mentoring organization is Friday (March 13) at
12 noon PDT:

hmmm -- I wonder if that is best -- it would put MPL projects in 
competition with all other python projects.

My first thought is that a SciPy application would be best -- with 
SciPy, numpy, MPL, Sage, Cython, etc, it's plenty big, but would have a 
bit more focus.

As an example, wxPython has been a mentoring organization for the last 
few years.

Not that I'm volunteering to put together the application....

Hi,

I have been unable to get the pdf backend to respect the settings for 
solid_joinstyle properly. When doing a plot using the default 
matplotlibrc I get rounded joins when saving as png but mitered when 
using pdf. I have also tried to set the joinstyle="round" directly in 
the plot command with the same result, pdf ignores the setting but png 
respects it.

I'm using a current build from svn on windows with python 2.5

/Jörgen

I have added these proposals to the PSF's GSoC 2009 wiki page here:

http://wiki.python.org/moin/SummerOfCode/2009

Feel free to add more ideas there.

The PSF will do the work of applying to Google -- we can encourage 
prospective students and mentors to apply through the PSF.

Cheers,
Mike

That's great Michael -- can you take the lead to get us registered by the
March 13th deadline?  I'm able to spend some time helping mentor as well.

Yes please. This would be extremely useful, not just for sympy and
sage. 

Cheers,

I think that's a great project idea -- nice and contained with an 
obvious goal.  I'd be happy to help out with that, as I probably know as 
much about the new backend interfaces as anyone.

I am also willing to mentor the project I volunteered for last year (the 
student dropped out in the eleventh hour).  That was to extract the math 
expression rendering engine out as a separate project.  It's hairier 
than it sounds, because it requires separating out the freetype wrappers 
as well, and parts of all the backends.  But this is something the Sympy 
and Sage folks were very interested in last year as well.

Cheers,
Mike

Hi Jeff,

Yes, I think this is what I needed. Many thanks.

Marjolaine.

Marjolaine:  Sounds like what you want is nearest neighbor interpolation.  The Basemap toolkit has an interp function that can do bilinear or nearest neighbor interpolation.  It's typically used for regridding, but I think it will work for your use case too.

Here's some pseudo-code:

from mpl_toolkits.basemap import interp
# here datarr is 2d data array on a regular grid with x,y coordinates
# defined by 1-d arrays x,y.  The arrays xout, yout describe the points
# on the transect. order=0 means nearest neighbor interp, order=1 means bilinear.
# dataout is the data interpolated to the transect.
dataout = interp(datarr,x,y,xout,yout,order=0)

Chicago Python User Group
=========================

For the first time ever (not really) ChiPy will return to the same  
venue two months in a row!  Sully's on the North Side, Near North and  
Clybourn.

Heading off the ChiPy efforts will be another sequel from last month.  
James Snyder will focus his ninja powers on all things scientific:  
NumPy, SciPy and Matplotlib.

Frank Duncan will extend the popular text editor VIM with pure Python  
(no vimscript or Lisp required!) allowing asynchronous communication  
to various other systems to build a better overall development  
environment. Or if you aren't into that sort of thing, you can at  
least extend vim with less pain and hassle.

Garrett Smith will present on Thrift with examples of Java/Python/C  
cross communication. Thrift is a software framework for scalable cross- 
language services development.

Our host for the meeting is Sully's House Tap Room & Grill.  All ages  
are welcome to this Free Private Event.  For those of age, Sully’s  
House offer 20 Beers on tap, and 35 Bottles - all craft and  
microbrewery, specializing in Belgium, Irish and German selections.   
Enjoy great Bar Food & Pizza from our Italian Oven and Daily  
discounted menu specials. The host has given us a dedicated  
bartender.  We will meet in the private party room on the second floor  
that is well equipped with top of the line video equipment – 100” HD  
screen & full A/V accessibility with Rock Band & Wii. Nice big space,  
bring a friend. Thanks Sully's!!!

This *will* be our best meeting yet.

Topics
------

   * Scientific with NumPy, SciPy and matplotlib ... -- James  (30min)
   * Extend VIM -- Frank  (30min)
   * Thrift with examples of Java/Python/C cross communication. --
