Re: [Matplotlib-users] Problems with Matplotlib and Python 2.6
I will check the matplotlibrc, but why should the Agg default backend not work? Because 'Agg' is a file-based backend, that you use when you want to generate a file as output (a PNG, f.e.), so savefig() works while show() not. You are looking for a GUI backend, something like TkAgg, GTKAgg or Qt4Agg, that calling show() will generate a window with the graph in it.

Re: [Matplotlib-users] Remove matplotlib 0.98 in order to install 0.99 on Ubuntu
On Sun, Sep 6, 2009 at 11:11, Tsviki Hirshtsviki.hi...@gmail.com wrote: Dear list, I were trying to install matplotlib 0.99 on my ubuntu interpid, I had previously installed and extensively used the great 0.98 version. There is not seem to be any .deb file for 0.99 on ubuntu.packages site yet, yes, we know and we are working on it (I'm holding this back a bit due to other committements, and because ubuntu is in feature freeze for the upcoming release). so I tried to untar and install the source file. The installation went smoothly, and when I print the value of __version__ from matplotlib within ipython, it says 0.99. However, when I try to import axes3d from matplotlib, it shouts at me that this module is disable in matplotlib 0.98 (!). So the question is, should I uninstall 0.98 before compiling the 0.99 source or what? well, this is hardly a question for this list (I see it more for ubuntu forums), but yes, either you remove python-matplotlib package (it's and 'apt-get update' away to reinstall if needed), or you play with sys.path, PYTHONPATH, and so on.

[Matplotlib-users] Simple stuff for a general-purpose matplotlib book
Hi all, as you might know, I'm writing a book about matplotlib. I'm approaching the last chapter, the one I would have liked to dedicate to science. Editors and I, anyhow, decided it would have been too much off-topic for the public we are targetting, so we have instead decided to present a series of real world use cases for matplotlib, situations where graphing can be useful. Some examples could be: - plot data from a database - read a csv and plot its data - webscraping to plot info on a webpage give the wide spectrum of category I can cover, I'd like to introduce some scientific examples, something every reader (and not specifically a math/phys guy can only) can read, understand and (avove all) appreciate :) . I'm thinking for example at line interpolation (generate some points and find the line/curve that better interpolate them). But what I'd like is to hear from you what simple example you'd like to propose to be in this book. Your collaboration would be really appreciate, because it will let the book be more user driven :) Cheers, -- Sandro Tosi (aka morph, morpheus, matrixhasu) My website: http://matrixhasu.altervista.org/ Me at Debian: http://wiki.debian.org/SandroTosi -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

you need to install the development package (in the common sense, for
your pacakge manager) to be able to compile code that dinamically
links to libz. For example on Debian with libz-dev (provided by
zlib1g-dev).
Install a similar package for your distrivution and try to recompile matplotlib.

[Matplotlib-users] Adapt animation_blit_qt4.py to a pure OO implementation (QT4 timerEvent)
Hi all, I'd like to adapt 'animation_blit_qt4.py' to a pure OO approach, removing pylab from the code and move to something near to 'embedding_in_qt4.py'. I tried a bit but failed miserably :( What I'd like to achieve is use something like in 'embedding_in_qt4.py' but that can be updated using the timerEvent / startTime paradigm (something similar to gobject.add_idle(func) but this time for Qt4).

Can you be more specific? Maybe post what you have along with a description
of how it is failing?
Eheh, sorry for being so generic: I wrote that email from work, while
the code I've worked on was at home ;)
So, the situation is this:
- animation_blit_qt4.py has a nice way to update the graph online,
using the timerEvent/startTimer
- animation_blit_qt4.py contains pylab staff (I want to avoid using)
- animation_blit_qt4.py uses the backend Qt4Agg not the backend object
- embedding_in_qt4.py uses an OO approach at embedding mpl in a qt4
widget/application.
The ultimate result I want to achieve is to embed mpl in a qt4
application but update the graph in realtime.
So I started modifying animation_blit_qt4.py to make it more OO :)
The attached script animation_blit_qt4_morph.py only replaced the
pylab parts with a mix of OO style and pyplot, and the timerEvent just
print the receive event without updating the graph.
As you can see, not much of what I need :(
What I'd like to achive is something similar to
embedding_in_qt4_morph.py but where the graph is updated
automatically like in an animation.
Your help will be appreciated a lot :)
Thanks,

sure, twinx() is what you're looking for; here is a simple example:

y1 = np.exp(-x)

ax1.plot(x, y1)
ax1.set_ylabel('Y values for exp(-x)')

ax2.plot(x, y2, 'r')
ax2.set_xlim([0,np.e])
ax2.set_ylabel('Y values for ln(x)')
ax2.set_xlabel('Same X for both exp(-x) and ln(x)')
The values on X has to be of the same scale, tough, else the graph

Hi Eric, thanks for the reply. On Sat, Feb 28, 2009 at 20:56, Eric Firing efir...@hawaii.edu wrote: It is not really a bug; it is an inherent limitation in mpl's default automatic Axes positioning. Axes positions are given in normalized coordinates relative to the figure, so if you shrink the height of the figure (relative to the default, for which the default positioning parameters are designed), there is less physical space available for the x-axis ticks, ticklabels, and label--and things can get cut off. If you are adjusting the figsize and/or the font size, then chances are you need to adjust these normalized coordinate Axes position parameters as well. Trial Oh, ok, now it's clear and error is typically needed; it can be facilitated by using the subplot adjuster widget in an interactive window (second to last button on the toolbar) to decide what looks good. Then use the figure.subplot.* entries Yeah, I used this to find 0.13 to be my number... in matplotlibrc, or call plt.subplots_adjust(bottom=0.15) (for example), or call it as a method of the figure you have just created. ...that I added this command and it worked.

Hi Chris, thanks for your reply, helpful as usual :) On Fri, Jan 30, 2009 at 18:59, Chris Walker chr...@chiark.greenend.org.uk wrote: Firstly, good luck with the book. cheers :) The sort of book I'd buy would explain how to use the combination of matplotlib/ipython/scipy/numpy to analyse data. Sadly, that would not the book I'll write :( The editor wanted to target another audience for the book: experienced python developers, with no knowledge of matplotlib; so an introductionary book, that will show even how to integrate mpl on GTK/WX application and on the web. I pushed to have something about science, and a chapter will be about that, but I need your (all) inputs, because my science days are long back in the past ;) - what are the (basic) things that, when you were beginning to use matplotlib, you wanted to see grouped up but couldn't find? - what would you like to see in a book about matplotlib? Start off by reading data from a file, plotting it and fitting a function to that data. That sounds something that could land in the science chapter. Plotting with related scales Sometimes it is useful to plot related scales on x1 and x2 axes. I've come across this several times in different contexts. In its simplest form, there is a linear relationship between the axes. In a mechanical test, you might want extension on the x1 axis and strain on the x2 axis (for example). Sometimes there is not a linear relationship. For example you might want to plot frequency (or photon energy) on x1 and wavelength on x2. An even more complex example is a Hall-Petch plot: (Yield Stress) = k/sqrt(Grain Size) So plotting 1/Sqrt(Grain Size) on the X1 axis gives a linear plot, but it would be useful to plot the grain size on the X2 scale. Err, I think I lost you ;) What you want is 2 plots on the same figure? so not 2 Ys for the same X (let's say X is time, and Y1 is stock price variation, and Y2 is the percentage change), you want X1-Y1 (let's say on the bottom-left) and X2-Y2 (on the upper-right): did I get you? ipython and emacs - Suppose I want to write a script to analyse some data (perhaps I want a record of what I've done, or perhaps I'd like to perform the same analysis on several data sets). I'd probably do so in emacs - but it is useful to do some experimentation in ipython - tab completion is particularly useful. I feel there must be a good way to do my experimentation in ipython and save the important bits in emacs - but I've not sat down and worked out an efficient way of doing this. I think the preferred way to do so it using ipython, and for now I plan only to show it on the book. Data aqcuisition and experimental control: - Writing a simple application to acquire data - ideally from multiple sources and plot the data as it is acquired. In my case I wanted to combine mechanical with electrical tests. A couple of interesting articles by G Varoquaux are listed at http://wiki.debian.org/DebianScience/DataAcquisition This is perhaps beyond the scope of the book, but it has come up on the mailing lists a couple of times. The ideal application would have a gui for simple use, but a command line (probably ipython) for more more complex use - perhaps performing a series of tests under different conditions. I thought about an example for this already! :) I thought to develop a sample application for GTK/WX that display some system value (like cpu usage or so, in this way everyone can run the example) plotting the information as it comes (for 30 secs, for example). Some discussion of plotting non gridded 2d data should also be in there. for example? Your suggestions are really appreciated :) And wish me good luck! I don't think it is the thrust of your book, but another book I was looking for is A cookbook of Numerical simulations of classic physics/engineering problems. For use by physicists/engineers who don't want to rewrite things from scratch. As said, even if my degree is in linear algebra, my science days are gone, so it won't be in the book, if not for that chapter about science and mpl. Good luck.

[Matplotlib-users] Matplotlib 0.98.5.2 - Debian packages available (source + amd64)
Hi all, due to some requests came lately, I decided to upload the temp Debian package for 0.98.5.2. They are available at [1]. If you're using an amd64 architecture, then you can take all those python-matplotlib*.deb and sudo dpkg -i deb them, if you're using another architecture, then (needs devscripts, build-essential installed): dget -x http://people.debian.org/~morph/matplotlib_0.98.5.2-1.dsc cd matplotlib-0.98.5.2 debuild -us -uc At this stage, the command will fails because there are some missing packages needed to build mpl. They are listed, so take them and aptitude install package list. You need both unstable and experimental repository in your /etc/apt/sources.list. Reiterate this process until the building proceeds. After a while (30mins ~ 1.5h) you'll have in .. the deb files to install on your machine. The building guidelines above are not complete, as it can't be in this email; in case of problem, reply to the lists, so other can leverage the replies.

I am not sure if compiling from source would help in this case, because the error seems to be related to a missing system (?) library and not to MPL or any of the backends. yes, it would help. because relinking to new lib will fix those broken links.

I haven't really used matplotlib's advanced features. There are some that I like, such as automatic legend placement and mathtext support. mathtext and latex support will be in the advanced features section The number of supported backends is impressive just by itself, making matplotlib much more useful. There are some little things such as the search order for the matplotlibrc file that make it possible to specify different settings for a given directory. There will be a part even on configuration (of course :) ). - what are the things you'd like to explore of matplotlib and never had time to do?

Re: [Matplotlib-users] [matplotlib-devel] What would you like to see in a book about Matplotlib?
Hello Andrew, thanks for taking the time to reply. First of all, let me clarify that I received a proposal (and not the opposite) so some decision were already made about the book format. On Mon, Jan 5, 2009 at 20:00, Andrew Straw straw...@astraw.com wrote: Hi Sandro, It's great news that a book may come out on MPL. Speaking as an aspiring university professor in neuroscience, I would like to see something that could be used as a resource for undergraduate students just learning Python and MPL. The cut of the book is for already experienced Python programmers. For sure, in the approaching chapter to mpl, I won't go too much into deep of python programming, and I suppose they'll be easy to read even for new comers. Due to this perspective, I think such a book would cover both numpy and MPL. The emphasis could clearly by on MPL, but basic numpy idioms and concepts should also be taught. Mh, the focus the editor would like to see is about introducing mpl + integrating into apps. The examples I have in mind for the pratical part of apps integration already cointains some sort of introduction to gather data and plot them (but I can't go to much on the scientific side :) ). I will propose a chapter like Matplotlib for the science and here your suggestion on what you'd like to see there is welcome. I think an example-driven approach would be very useful -- something like an undergraduate laboratory experiment where students measure and plot raw values and compute histograms and statistics (e.g. mean and std). More advanced sections might perform statistical comparisons of different treatments (e.g. using chi squared, KS and/or T tests), do linear least squares fitting (with np.linalg.lstsq), and possibly non-linear curve fitting using something like scipy.optimize.fmin. That could be a beginning of that chapter contents: more more more ideas :) That's my self-serving $0.02, since you asked! :) And they are very much welcome!! You may also want to speak with John Hunter and Fernando Perez about the possibility of collaborating -- they've already done some work towards a book, too. I'm sure be happy to hear their voice on this product, but (given the preamble) I don't know if the editor would be fine with co-authorship; I'll ask, just to be sure.

actually, I think matpoltlib.pyplot still has all of pylab in it, just not
all of numpy also.
yes, pylab glues pyplot and numpy together
So yes, do that, but what I meant was to focus on using
the OO interface, rather than the state machine interface:
rather than 'gca', 'gcf', etc, store references to the figures and axis,
etc:
this kind of thing:
fig = plt.Figure()
ax = fig.add_subplot(111)
ax.plot([1,2,3])
ax.set_title('hi mom')
ax.grid(True)
ax.set_xlabel('time')
ax.set_ylabel('volts')
Ahhh ok, now I got it: I always use the style above, so I didn't know
the difference :) A reference to the doc is:

I don't know if something bad has happened in mpl code or something in
Debian is broken right now (graphviz?), but it would help me if
someone can confirm this is not happening only on my box.
Thanks,

The doc compilation is fine, the show-inheritance is fixed, but just a confirmation: what was the page with the clickable image? I seem to remember 'api/artist_api.html' but now the image in it doesn't allow to be browsable. I'll let you know if something else comes out.

Sphinx changed the way that cross-reference urls are stored in the document tree. I have updated matplotlib to use an approach that work for Sphinx both before and after this change (SVN r5940). I don't consider this a show-stopper if it's too late to push another matplotlib update out. Long term, this functionality will move to Sphinx itself, so these disconnects will hopefully get caught sooner. Great, thanks! anyhow, we're still playing with a rc version, so there's room for it to make into the final release. For Debian, we still need (I think) a couple of day to upload mpl, because we need first sphinx 0.4.2 to enter unstable, then we can upload.
