Subject: [job] top-flight graphicist needed for climate science & media 
group
To: mat...@li...

Please apply if interested--or forward to any associates you believe 
would be good! Much appreciated; this is a very important position for 
us and we're looking for a real star. Many thanks--
Ben Strauss
Associate Director, Strategic Initiatives
Climate Central
 Seeking Immediately:
 Experienced Graphic Designer for Climate Science & Media Group's TV,
 Web Productions
 Objective
Climate Central seeks an experienced, inspired and technically 
proficient graphic designer or data visualization expert--ideally versed 
in both art and science--to develop conceptual and data-driven 
visualizations from climate science research for broadcast TV and 
Internet. A group of internationally recognized scientists and 
communicators, Climate Central is dedicated to producing vivid media 
based on sound climate change science, and has within its first 18 
months already appeared on PBS's The NewsHour with Jim Lehrer, 
nytimes.com <http://nytimes.com/>, bloomberg.com 
<http://bloomberg.com/>, TIME.com, Newsweek and Scientific American. We 
will begin this Princeton, NJ position as a 90-day contract; successful 
performance will lead to full-time hire.
 Description
Climate change presents one of the greatest communications challenges of 
all time. Many words have been printed, but Climate Central aims to 
develop an unmatched collection of clear, compelling, and science-based 
graphics and animations to tell the story visually. We are currently 
expanding capacity in this area.
The Designer will collaborate with staff scientists and producers, as 
well as design colleagues, to produce static graphics and end-to-end 
broadcast-quality animated visualizations tailored for a general 
audience. Each product must be accessible and understandable, yet vivid 
and scientifically rigorous.
The position will involve the development, maintenance, and application 
of a wide variety of tools for analyzing data and production, with some 
emphasis on tools for geographical display of information (GIS, Google 
Earth, Google Maps, generic maps). An important dimension of this 
position will be working with NASA scientists and satellite data to 
develop an Earth-from-space "sky witness" collection of climate change 
visualizations.
For a sample of Climate Central's designs and animations to date, see 
the static graphics and videos at climatecentral.org 
<http://climatecentral.org/>.
 Qualifications
Significant experience (5+ years best) in scripting, data conversion, 
modeling, rendering and compositing, and handling large datasets, is 
required. Candidate should show initiative and be a self-starter and 
self-teacher able to work well from high-level direction. We are 
looking for someone with commitment to excellence, attention to detail, 
and passion for work and the subject.
Applicants should be proficient with the following tools, languages and 
data formats we regularly use:
• Maya, After Effects, Illustrator, Photoshop, Google Earth/Maps
• Python, Javascript
• ESRI Shapefile, KML
...and it would also be helpful if you are familiar with:
• MATLAB/Octave, VTK, Blender, Imagemagick, Gimp, QGIS, GDAL/OGR, 
NCAR NCL
• C/C++
• NetCDF, CSV, HDF
 To Apply
To apply, please send a cover letter, resume and link to your portfolio. 
We are looking for thoughtful, personalized cover letters that 
demonstrate applicants' qualifications and work style. Send materials as 
text in the body of an email message to jo...@cl... 
<mailto:jo...@cl...>; please put "graphics" in the subject 
line. If you send attachments, they must be in pdf format.
No phone calls, please.
Salary is competitive and will depend on experience. Climate Central 
offers excellent benefits, a delightful workplace, and the opportunity 
to play a crucial role in an organization with a mission.
Climate Central is an equal-opportunity employer and does not 
discriminate based on anything except how good you are at your work. 
People of color and individuals from other underrepresented groups are 
strongly encouraged to apply.
 About Climate Central:
Climate Central combines sound science and vivid media to increase 
public understanding and attention to the climate challenge. In less 
than two years of operation, our work has already appeared on PBS 
NewsHour, nytimes.com <http://nytimes.com/>, bloomberg.com 
<http://bloomberg.com/>, time.com <http://time.com/>, newsweek.com 
<http://newsweek.com/>, Scientific American, and beyond. Our staff and 
board include internationally recognized climate scientists and 
communications experts. Visit our interim website climatecentral.org

I tried the code you supplied and I didn't get it to work with the *angles*
keyword, I got:
"ValueError: shape mismatch: objects cannot be broadcast to a single shape"
I have matplotlib.__version__ = '0.98.5.2'.
Although after thinking about it for a while I did:
from scipy import *
import matplotlib.pyplot as plt
X,Y = meshgrid(arange(64),arange(64)) # a bit bigger just to see what it
looks like
angles = arange(0,4*pi,4.*pi/X.size) # just creating a set of angles
u = cos(angles)
v = sin(angles)
c = arange(u.size) # the colours!
c.shape = X.shape
plt.quiver(X, Y, u, v, c, pivot='middle',minlength=0.04, width=0.05,
headwidth=1,scale=50)
that is, the angles are converted to "u" and "v" parameters.
Anyway. That is how I got it working.

I set the axes positions by hand in these situations using add_axes(). So:
fig = plt.figure()
width1 = 0.3
width2 = 0.2
height = 0.75 / 3
left = 0.1
bottom = 0.15
axes_column0 = []
for i in range(3):
 axes_column0.append(fig.add_axes([left, bottom + i*height, width1, 
 height]))
axes_column1 = []
for i in range(3):
 axes_column1.append(fig.add_axes([left+width1, bottom + i*height, 
 width2, height]))
axes_column2 = []
for i in range(3):
 axes_column2.append(fig.add_axes([left+width1+width2, bottom + i*height, 
 width1, height]))
You can adjust this slightly if you want to put gaps between the subplots, 
or otherwise use axes.set_yticklabels([]) (for example) to get rid of 
unwanted tick labels.
Plot to each of the subplots using something like:
axes_column0[1].plot(x,y)

Thanks,
I thougth that this could be the problem. Actually i fixed it by myself.
Thanks anyway.
Cheers

Hi Per,
You need 2*N, not N*2 arrays here. I think you're also trying to use 
absolute values so you probably need something like this:
plt.errorbar([1,2,3],[1,2,3],yerr=np.abs(a.T-[1,2,3]))
I hope this is what you're after,
Gary R.

I was able to get it working on my home machine, but can't get it installed
on my webhost. I get this error when I try to import the module:
