[Matplotlib-users] Scientific Software developer wanted in Seattle.
Scientific Software Developer NOAA Emergency Response Division Help us develop our next-generation oil spill transport model. Background: The Emergency Response Division (ERD) of NOAA's Office of Response and Restoration (ORR) provides scientific expertise to support the response to oil and chemical spills in the coastal environment. We played a major role in the recent Deepwater Horizon oil spill in the Gulf of Mexico. In order to fulfill our mission, we develop many of the software tools and models required to support a response to hazardous material spills. In the wake of the Deepwater horizon incident, we are embarking on a program to develop our next-generation oil spill transport model, taking into account lessons learned from years of response and this major incident. General Characteristics: The incumbent of this position will provide software development services to support the mission of the Emergency Response Division of NOAA's Office of Response and Restoration. As part of his/her efforts, independent evaluation and application of development techniques, algorithms, software architecture, and programming patterns will be required. The incumbent will work with the staff of ERD to provide analysis on user needs and software, GUI, and library design. He/she will be expect to work primarily on site at NOAA's facility in Seattle. Knowledge: The incumbent must be able to apply modern concepts of software engineering and design to the development of computational code, desktop applications, web applications, and libraries. The incumbent will need to be able to design, write, refactor, and implement code for a complex desktop and/or web application and computational library. The incumbent will work with a multi-disciplinary team including scientists, users, and other developers, utilizing software development practices such as usability design, version control, bug and issue tracking, and unit testing. Good communication skills and the knowledge of working as part of a team are required. Direction received: The incumbent will participate on various research and development teams. While endpoints will be identified through Division management and some direct supervision will be provided, the incumbent will be responsible for progressively being able to take input from team meetings and design objectives and propose strategies for reaching endpoints. Typical duties and responsibilities: The incumbent will work with the oil and chemical spill modeling team to improve and develop new tools and models used in fate and transport forecasting. Different components of the project will be written in C++, Python, and Javascript. Education requirement, minimum: Bachelor's degree in a technical discipline. Experience requirement, minimum: One to five years experience in development of complex software systems in one or more full-featured programming languages (C, C++, Java, Python, Ruby, Fortran, etc.) The team requires experience in the following languages/disciplines. Each incumbent will need experience in some subset: * Computational/Scientific programming * Numerical Analysis/Methods * Parallel processing * Desktop GUI * Web services * Web clients: HTML/CSS/Javascript * Python * wxPython * OpenGL * C/C++ * Python--C/C++ integration * Software development team leadership While the incumbent will work on-site at NOAA, directly with the NOAA team, this is a contract position with General Dynamics Information Technology: http://www.gdit.com/default.aspx For more information and to apply, use the GDIT web site: https://secure.resumeware.net/gdns_rw/gdns_web/job_detail.cfm?key=59436show_cart=0referredId=20 if that long url doesn't work, try: http://www.resumeware.net/gdns_rw/gdns_web/job_search.cfm and search for job ID: 179178 NOTE: This is a potion being hired by GDIT to work with NOAA, so any questions about salary, benefits, etc, etc should go to GDIT.

I tried editing the image with PIL, but as soon as I load the image it becomes rasterized (=a small matrix of pixels, unusably ugly). right, PIL is a raster tool. There is some hope that you could have PIL rasterize it with much higher resolution for better quality, but it's really not what you are looking for. Is there any way to edit the EPS in matplotlib? no -- that is not at all what MPL is about. Or maybe some other, easier way to add the plot marks ex post? I am no expert on vector graphic formats. I'd use a vector graphics program. EPS is almost the same as Adobe Illustrator's format, for instance. InkScape is a really nice cross platform open source vector graphics tool. It's native format is SVG. I'll bet you could find a way to convert the EPS to svg, or, if you're lucky, InkScape can read EPS. The nice thing about SVG is that being XML, you may be able to manipulate it directly with a python script or something, if you have many similar plots to do, so you don't have to point and click on each one. Inkscape can be used as a command line SVG renderer, too.

vbkhp wrote:
Hi,
Could anyone tell me how can I remove matplotlib completely on Mac?
I was on version 0.99 and I wanted to upgrade to version 1.0 so i removed
the matplotlib directory and the egg file (besides the pylab.py,
pylab.pyo, and pylab.pyc files),
That should have done it -- except perhaps for your matplotlibrc
file(s), but you may want to keep that anyway.
and installed the new version using
.dmg file matplotlib-1.0.0-python.org-py2.6-macosx10.4. Now, I can
import and work with pylab when I call it from the terminal, but I can
not import it other places like IDLE. I get the following error.
If it's different from IDLE than the command line, that indicates that
you may be running two different versions of Python. You have at least
two -- the one that Apple supplied and the python.org one.
Process: Python [922]
Path:
/Library/Frameworks/Python.framework/Versions/2.6/Resources/Python.app/Contents/MacOS/Python
This is the python.org one -- which is where that dmg file should have
put the new matplotlib. So which are you running when you use the
command line?
one way to tell is with by checking the __file__ attribute on an
arbitrary module:
In [10]: import numpy
In [11]: numpy.__file__
Out[11]:
'/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/numpy/__init__.pyc'
So mine is the python.org one -- the Apple one is in /System/
Once you've got that cleared up, at least you can know where your
problem is -- sorry I can't help you with that crash report.
One more thought -- IDLE uses TK, ans so does (optionally) MPL --
perhaps there is a version conflict there? (I'm not a IDLE or Tk user,
so I don't know if that's likely). You might try testing other back ends:
import matplotlib
matplotlib.use('agg')
for instance.

Can matplotlib be used to accomplish this? If so, could someone direct me to where this is discussed? I don't think so directly. MPL uses a 32 bit image buffer internally, and that's what gets saved out in the PNG. You can post-process the image with something like ImageMagick. Another alternative is to use PIL -- you can grab the matplotlib buffer, make a PIL image out of it, and use PIL to convert to an 8-bit palleted image. For that matter, you could probably bypass MPL, and use numpy to create the 8-bit image you want, and PIL to save it as a PNG. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

I suspect the latest binary is a mistake, but if not, it should be Clearly labeled as for the ApplePython2.6-osx-10.6, and ideally, a python.org compatible binary provided as well.

to enable draggable mode. You can repeatedly call this func to toggle

Might I suggest that that be made:
leg.draggable(True)
leg.draggable(False)
or
leg.draggable('on')
leg.draggable('off')
or even a property:
leg.draggable = True
or some such. I'd be nice not to have to keep track of the current state.

A couple more thoughts on this: 4) Don't put clf() and cla() all over the place. absolutely -- my addition to this is to use the OO API more than the pylab one. Put all your plotting code into functions that take an axes object as a parameter, then go from there. That way you have separated the generation of figures (collections os axes) from the plotting itself. you can do the same at a higher level too -- put your code that creates the figures in a function that take a figure as an argument -- then you can use the same code to generate PDFs, embed in a GUI, etc. HTH, -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov -- This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

We have developed a heuristic solution which packs the Frames automatically according to a pattern that can be recognized after a user has manually repositioned a few Frames on the screen. For example, some users tend to align their figures in a row, others subdivide the available space for different groups of figures, and so on. Please let us know if anyone is interested to integrate this heuristic packing into matplotlib. The important question is: How can we set the position of a Figure on the screen using matplotlib?

There is also a fair bi tof time spent pushing data to the back-end. I think to really get the benefit of OpenGL, you'd need the back-end to be semi-perstent -- you'd pass data in, and teh back-end would render it without having to pass the data in again. This would only support transforms that the back-end supports (linear only?). However, I think there could still be areal performance benefit bey breaking the transform pipeline into two parts -- one from arbitrary coordinates to something orthogonal and linear, and then a final one from that to screen coordinates (zooming and panning). Then you'd at least get full hardware accelerated performance for zooming and panning We're doing this for a high-performance interactive mapping app, and it's working pretty well.

The key here is that GUI toolkits run a Mainloop() to process user input, and once you've started that, they block python until it's done. What Ipython does is (optionally) start up the GUI toolkit in another thread, so that the main interactive prompt is not blocked.

Unfortunately, what this means is that the amount of space for the axis labels varies with the size of the figure, as you've discovered. The default for a single axes in a figure is: (0.125, 0.1, 0.9, 0.9) so you might try something like: axes.set_position((0.125, 0.15, 0.9, 0.85) ) what is best depends on what size you want your figure to look good at. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Re: [Matplotlib-users] wx and matplotlib
Werner F. Bruhin wrote: I am trying to put together a wxPython frame using py.aui to show multiple matplotlib.figures/canvas. I'd recommend you take a look at wxMPL -- it's a nice way to embed MPL in wx. Would like that each figure takes x percentage of available screen estate. I.e. would like e.g. to have 2 rows with 3 columns of figures/statistics, i.e. 6 graphics. To be clear with the vocabulary -- in MPL, a figure would be one wxWindow. In that you can put multiple axes which show the actual plots (sometimes referred to as subplots). In this case, I'm not sure if you want more than one MPL figure. If the total screen estate is too small then there should be scrollbars per figure/canvas. If you want multiple figures, than this isn't really an MPL question. You'd do that layout the same way you would with any other set of wxWindows -- probably putting them all on a wxScrolledWindow, in Sizers, and giving them a minimum size. With a single MPL Figure, it would be similar, put it on wxScrolledWindows, with a minimum size set.

Re: [Matplotlib-users] Backend neutral idle event won't repeat
John Hunter wrote: Wriing a GUI neutal idle event handler is not easy -- I've spent some time on it but crashed and burned on tk I think it would be great if we could abstract the idle handler and timeout handler across the GUIs so that mpl animation would be easier, but to date this has eluded me. Maybe getting away from the Idle event approach would be the way to go. I've done a lot of (non-MPL) wx work, including animations, and NEVER found a use for the idle event. For animation work in wx, using a wx.Timer, and often a call to wx.Yield seems to generally be the way to go. Perhaps this same approach could be done on the other back ends as well. As for idle events, I've found them to be useless because you get lots of them when you don't need it, and may not get them when you do. In wx at least, an Idle event is triggered when the event loop _becomes_ empty. That means that when the user is moving the mouse and there is no mouse_move event handler, you get this huge string of idle events. However, if the user is doing nothing for a bit, you get one event, then nothing until the user does something again. I can see the appeal of an Idle event -- there are all sorts of things you might want to do when the app is idle, but the reality is that what you really want to know is when the app is _going to be_ idle for a bit, and there is no way to know that (at least not without Guido's time machine, anyway...). I've lost track of what problems you're trying to solve with idle events, but maybe an abstraction of a timer system would be a more robust approach, for animations, anyway. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/ORR(206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Matplotlib-users] Turning off the timezone (and more) in AutoDateFormatter
Hi all,
I'm passing in None for the timezone in AutoDateFormatter.
What I am getting is UTC, but what I want is nothing.
Looking at the code, I see lines like:
self._formatter = DateFormatter(%H:%M:%S %Z, self._tz)
so my None is getting passed through. Then in DateFormatter, I see:
if tz is None: tz = _get_rc_timezone()
Which looks like it's getting a timezone from an rc parameter. This
strikes me as not such a good idea. Far too easy to get the timezone
wrong -- I'm not sure there should be such a thing as a default time zone.
However, the issue at hand is that I want to not show the timezone at
all. I would have thought that None would be a good way to spell that,
but it's taken already to mean default.
So that means editing/overriding AutoDateFormatter. The way it's
written, I pretty much have to re-write the entire thing, which isn't so
bad, but it might be nicer if we could make it easier to override just
part of it.
One idea:
Some say that the right way to spell case/switch in Python is a
dict, rather than a collection of if--elifs. So in this case, we could
make a dict of format strings, something like below.
I've tried this, and I can now easily override the formatting for a
particular time range, like so:
Formatter = mpl.dates.AutoDateFormatter(locator, tz=None)
# edit the format strings to remove the TZ spec
# this only works with my custom version of AutoDateLocator
Formatter.format_strings[1.0/24.0] = %H:%M:%S
I do agree with the comments that there are other ways to improve this,
but maybe this is a start.
-Chris
class AutoDateFormatter(ticker.Formatter):
This class attempts to figure out the best format to use. This is
most useful when used with the :class:`AutoDateLocator`.
# This can be improved by providing some user-level direction on
# how to choose the best format (precedence, etc...)
# Perhaps a 'struct' that has a field for each time-type where a
# zero would indicate don't show and a number would indicate
# show with some sort of priority. Same priorities could mean
# show all with the same priority.
# Or more simply, perhaps just a format string for each
# possibility...
def __init__(self, locator, tz=None):
self._locator = locator
self._formatter = DateFormatter(%b %d %Y %H:%M:%S %Z, tz)
self._tz = tz
self.format_strings = { 365.0 : %Y,
30.0 : %b %Y,

[Matplotlib-users] using MPL and ipython run command
Hi all
I'm sure this is documented somewhere, but I can't find it.
I'm finally getting around to learning ipython, which is pathetic as it
sure seems like a great tool.
Anyway, I want to be able to have a simple script that does some
plotting with MPL, and run it with python's run. Then change the
script and run again, and have the plot updated -- this does not seem to
happen. It appears to work if I close th figure by clicking on the
Window close button, then run, but that's kind of a pain.
What am I missing?
example script:
import matplotlib.pyplot as plt
import numpy as np
x = (1,2,3,4,5,6,7,8)
y = (6,2,6,4,6,4,7,5)
plt.plot(x, y)
plt.grid('on')
plt.show()
the I want to be able to do:
In [32]: run test_ipython.py
get a plot, then change some of the numbers in the script and:
In [33]: run test_ipython.py
then get an updated plot.
It's not doing that now.
what am I missing?
thanks,
-Chris
