[Matplotlib-users] matplotlib ignores CocoaAgg backend in matplotlibrc
I have the CocoaAgg backend specified in matplotlibrc in ~/.matplotlib/ as: backend : CocoaAgg However, when I plot, matplotlib uses the TkAgg backend in spite of this. -- Christopher J.

[Matplotlib-users] CocoaAgg backend status?
I was just wondering what the status of the CocoaAgg backend is since there is not much info available. Can it be used interactively w/ipython? Can it be used to embed mpl in a cocoa app and take advantage of all the xcode/interface builder stuff in OS X?

(Without changing the matplotlib code directly) I want to be able to extend it by ex. dashed lines or others.. i sometimes have a large number of plots to do, and the 7 default plot colors are not enough... I know I could manually make a handler in my program to handle the colors when I plot... but it would seem nicer if I could just pass a list of plot colors to matplotlib. I just made a chance in svn to expose the default color list. Here is an ipython session that shows how to use it: In [1]: import matplotlib.axes as mplaxes In [2]: x, y = rand(2,100) In [3]: plot(x, y, 2*x, 2*y) Out[3]: [matplotlib.lines.Line2D instance at 0x8f2dc8c, matplotlib.lines.Line2D instance at 0x8f2dd6c] In [4]: mplaxes._process_plot_var_args.defaultColors = ['red', 'darkslategray', 'wheat'] In [5]: clf() In [6]: plot(x, y, 2*x, 2*y) Darren, we might want to expose this in the matplotlib.conf, but perhaps is it a rare enough request that it is enough to let people tweak it manually when needed. The only thing that is a bit ugly is that Axes._process_plot_var_args has the leading underscore indicating it should not be used outside of mpl, but this is easy enough to remedy...

Unlikely, we haven't changed anything in that code. One thing you can do, it is fairly labor intensive, is to paste the toolbar code from backend_gtk into your script and slowly start hacking away at it to see which gtk call is causing your problems. I don't see an easier way. Alternatively, you could get tkagg, qtagg or wxagg installed. If you want to stick with gtk, I can provide a sample script for you that defines the toolbar inline so you can hack on it.

What version of matplotlib and Cairo are you using? It sounds like it

your matplotlibrc file, and also set verbose.level to debug-annoying

Hello all,
I am trying to get a setup where I can have an interactive environment
and output to PDF files as needed. I currently have this setup
working in OS X 10.5 without problems. However, I cannot get a
similar setup working on linux. The best I have been able to do is by
using GTKCairo but it has a problem with rendering numbers in math
mode. Specifically when I put a number, say -3.1415, into a string
the decimal is converted to a : and the - is turned into an i.
Below is an example that gives this error:
import numpy
from pylab import *
x = numpy.arange(1,100,1)
e1=-1.8
e2=-2.1
y = x**2
z = x**-2
f = figure(num=1)
f.clear()
ax = f.add_subplot(111)
p = ax.plot(x,y)
p1 = ax.plot(x,z)
title('This works -2.1 but this doesnot $-2.1$')
legend((p[0],p1[0]),(r'$x^{%.2g}$'%(e1),r'$x^{%.2g}$'%(e2)))
draw()
savefig('test.pdf')
The output looks fine in GTKAgg but then I get an error on glib.
Anyone have any ideas on how to get it working?

I tried the same thing with 0.90.1 and then I only get 2 handles for the same script and no increase on subsequent calls with or without close(all). /Jörgen - SF.Net email is sponsored by: The Future of Linux Business White Paper from Novell.

Thanks for the background Barry. I was asking because I have a bit of image processing/analysis code (numpy/mpl/pil) that I would like to build a GUI front-end for. As I am a recent convert to the osx world, I thought it would be very slick to be able to do this with the xcode/IB tools. Since this is not high-priority work right now, I'll stick with wx for now.

The fact both use the mail protocol doesn't change the fact they're different objects. But of course that's only a philosophical problem.

i am having trouble installing matplotlib from source and thought i would post my issue here. i download matplotlib version 0.91.0 i am using a version of scientific linux, so i can't use rpm packages for some packages # uname -a Linux labcalx 2.6.23.8 #1 Fri Nov 23 10:54:41 EST 2007 i686 i686 i386 GNU/Linux i verified that i had the following packages installed via rpm: matplotlib core: zlib, zlib-devel, libpng, libpng-devel, freetype, freetype-devel, freetype-utils • gtk backend: gtk2-devel, gtk+-devel, pygtk2, glib-devel, pygtk2-devel, gnome-libs-devel, pygtk2-libglade • tk backend: tcl, tk, tkinter (and tk-devel) the wxpython package is not available on rpm for me (at least not that i can find) so i downloaded the source. that also seemed to compile and install fine. the libraries are in /usr/local/lib and that path is referenced in file /etc/ld.so.conf.d/wx.conf the ldconfig command seemed to find this okay and that looks like it should work. as per the user install guide, i downloaded setuptools-0.6c7-py2.3.egg without any trouble here is my output from the build command: # python setup.py build BUILDING MATPLOTLIB matplotlib: 0.91.0 python: 2.3.4 (#1, Oct 9 2006, 18:22:22) [GCC 3.4.5 20051201 (Red Hat 3.4.5-2)] platform: linux2 REQUIRED DEPENDENCIES numpy: 0.9.8 freetype2: 9.7.3 OPTIONAL BACKEND DEPENDENCIES libpng: 1.2.7 Tkinter: Tkinter: 1.177, Tk: 8.4, Tcl: 8.4 wxPython: no * wxPython not found Gtk+: gtk+: 2.4.13, glib: 2.4.7, pygtk: 2.4.0, pygobject: [pre-pygobject] Qt: no Qt4: no Cairo: no OPTIONAL DATE/TIMEZONE DEPENDENCIES datetime: present, version unknown dateutil: matplotlib will provide pytz: matplotlib will provide OPTIONAL USETEX DEPENDENCIES dvipng: no ghostscript: 7.07 latex: 3.14159 pdftops: 3.00 EXPERIMENTAL CONFIG PACKAGE DEPENDENCIES configobj: matplotlib will provide enthought.traits: matplotlib will provide [Edit setup.cfg to suppress the above messages] running build running build_py copying lib/matplotlib/mpl-data/matplotlibrc - build/lib.linux-i686-2.3/matplotlib/mpl-data copying lib/matplotlib/mpl-data/matplotlib.conf - build/lib.linux-i686-2.3/matplotlib/mpl-data running build_ext building 'matplotlib.backends._backend_agg' extension g++4 options: '-fno-strict-aliasing -DNDEBUG -O2 -g -pipe -m32 -march=i386 -mtune=pentium4 -D_GNU_SOURCE -fPIC -fPIC' creating build/temp.linux-i686-2.3 creating build/temp.linux-i686-2.3/agg23 creating build/temp.linux-i686-2.3/agg23/src creating build/temp.linux-i686-2.3/src creating build/temp.linux-i686-2.3/CXX compile options: '-I/usr/lib/python2.3/site-packages/numpy/core/include -I/usr/include/libpng12 -I/usr/local/include -I/usr/include -I. -Isrc -Iswig -Iagg23/include -I. -I/usr/include/freetype2 -I/usr/local/include -I/usr/include -I. -I/usr/include/python2.3 -c' g++4: src/_image.cpp In file included from /usr/include/python2.3/Python.h:8, from src/_image.cpp:7: /usr/include/python2.3/pyconfig.h:850:1: warning: _POSIX_C_SOURCE redefined In file included from /usr/include/c++/3.4.3/i386-redhat-linux/bits/os_defines.h:39, from /usr/include/c++/3.4.3/i386-redhat-linux/bits/c++config.h:35, from /usr/include/c++/3.4.3/iostream:44, from src/_image.cpp:1: /usr/include/features.h:150:1: warning: this is the location of the previous definition g++4: agg23/src/agg_rasterizer_scanline_aa.cpp g++4: CXX/IndirectPythonInterface.cxx In file included from /usr/include/python2.3/Python.h:8, from ./CXX/WrapPython.h:47, from ./CXX/IndirectPythonInterface.hxx:41, from CXX/IndirectPythonInterface.cxx:38: /usr/include/python2.3/pyconfig.h:850:1: warning: _POSIX_C_SOURCE redefined In file included from /usr/include/sys/time.h:22, from ./CXX/WrapPython.h:43, from ./CXX/IndirectPythonInterface.hxx:41, from CXX/IndirectPythonInterface.cxx:38: /usr/include/features.h:150:1: warning: this is the location of the previous definition g++4: src/backend_agg.cpp In file included from /usr/include/python2.3/Python.h:8, from ./CXX/WrapPython.h:47, from ./CXX/Extensions.hxx:48, from src/ft2font.h:18, from src/backend_agg.cpp:24: /usr/include/python2.3/pyconfig.h:850:1: warning: _POSIX_C_SOURCE redefined In file included from /usr/include/c++/3.4.3/i386-redhat-linux/bits/os_defines.h:39, from /usr/include/c++/3.4.3/i386-redhat-linux/bits/c++config.h:35, from /usr/include/c++/3.4.3/iostream:44, from src/backend_agg.cpp:4: /usr/include/features.h:150:1: warning: this is the location of the previous definition /usr/lib/python2.3/site-packages/numpy/core/include/numpy/ufuncobject.h:9: error: 'intp' has not been declared /usr/lib/python2.3/site-packages/numpy/core/include/numpy/ufuncobject.h:9: error: 'intp' has not been declared In file included from /usr/include/python2.3/Python.h:8, from ./CXX/WrapPython.h:47, from ./CXX/Extensions.hxx:48, from src/ft2font.h:18, from

Re: [Matplotlib-users] CocoaAgg backend status?
Stephen, The CocoaAgg backend is not supported in IPython. You can use it in the non-interactive form (i.e. with a pylab.show() but you will have to close the window in order to return control to the IPython shell). It is possible to embed an MPL plot in a Cocoa application using the same trick as the CocoaAgg backend (rendering the plot using the Agg backend and then turning the rasterized bitmap into and NSBitmapImageRep and then displaying it in an NSImageView). I've posted previously about a py2app plugin which does just that and has an IB palette, but I haven't had time to update the IB palette to use the IB 3 plugin API yet. It uses Cocoa Bindings to provide data to the plot. I'm happy to send it to you as is, or you can wait until it's IB 3 ready. We (at my work) are just starting to think about writing a more direct Quartz backend for mpl. A native backend would let a matplotlib view participate in newer Cocoa technologies, such as resolution independence and CoreAnimation (it's possible with the current backend method, but not quite as flexible). This will make embedding easier, but will not solve the IPython issues. For now, one of the other backends, such as WXAgg or TkAgg is probably the better bet on OS X. barry On Dec 5, 2007, at 7:37 AM, Stephen Uhlhorn wrote: I was just wondering what the status of the CocoaAgg backend is since there is not much info available.

If you are looking into writing a Quartz rendering backend, you may want to start with the matplotlib transforms branch (which should become the trunk shortly, once the 0.91 release bugs get shaken out.) The number of methods that a backend writer must provide has been greatly reduced on that branch.

Maybe that was asked on matplotlib-devel though (I filter them to the same place). I suspect the official egg can somehow be patched, but I find it easier to just build my own and put that on pythonmac. Ideally, there would be only one binary version, and it would work with either Tcl/Tk.

Re: [Matplotlib-users] filehandle leaks in matplotlib 0.91.1
I'm on a Linux box (I'm assuming you're on Windows, since you mentioned Process Explorer), and I wasn't able to find any file handle leaks, as such, but I did see that font files were being opened many more times than they need to be. If you're able to run from Subversion, r4633 has a fix for this. I'm curious if it fixes your symptoms. Cheers, Mike Jörgen Stenarson wrote: hi, I think the new 0.91.1 has some kind of file handle leak at least when using python 2.4, tkagg, and within ipython.

What's happening is that it isn't finding the Bakoma Computer Modern

actually under a different character code.
So... we need to track down why it's looking in the wrong place.

[Matplotlib-users] converting GMT color palettes to pylab colormaps

working in OS X 10.5 without problems. However, I cannot get a
similar setup working on linux. The best I have been able to do is by
using GTKCairo but it has a problem with rendering numbers in math
mode. Specifically when I put a number, say -3.1415, into a string
the decimal is converted to a : and the - is turned into an i.
Below is an example that gives this error:
import numpy
from pylab import *
x = numpy.arange(1,100,1)
e1=-1.8
e2=-2.1
y = x**2
z = x**-2
f = figure(num=1)
f.clear()
ax = f.add_subplot(111)
p = ax.plot(x,y)
p1 = ax.plot(x,z)
title('This works -2.1 but this doesnot $-2.1$')
legend((p[0],p1[0]),(r'$x^{%.2g}$'%(e1),r'$x^{%.2g}$'%(e2)))
draw()
savefig('test.pdf')
The output looks fine in GTKAgg but then I get an error on glib.
Anyone have any ideas on how to get it working?
Regards,
Brian

If you mean why can't it be built that way in the first place, I don't know. The guy who builds it apparently doesn't read this list, Sure he does (if you mean the matplotlib list), and he did ask about it right before this release. Maybe that was asked on matplotlib-devel though (I filter them to the same place). It was on matploblib-devel. I'll start skimming that newsgroup. I suspect the official egg can somehow be patched, but I find it easier to just build my own and put that on pythonmac. Ideally, there would be only one binary version, and it would work with either Tcl/Tk. Is that possible? or is this like the old wx situation, where it can only be run with the same version it is built against. Arrggg! I hope not. The version I build *can* be used with the built in Tcl/Tk. The version Charlie Moad builds cannot be used with TkAgg and a 3rd party Tcl/Tk -- it not only won't use the library, but it also acts flaky. Older versions crashed. 0.91.1 doesn't crash, but import of pylab fails with a traceback. For some reason it seems to be necessary to have a 3rd party Tcl/Tk installed when building matplotlib. It seems a shame. Tkinter in Python 2.4 was the same way, but that got fixed in Python 2.5 (I don't whether the installer got fixed or whether whoever builds Mac Python 2.5 installed a 3rd party Tcl/Tk). If there really do need to be two, then they should be labeled somehow, and both be up on python mac. Since there don't need to be two versions this is not necessary. However, Charlie Moad appears to be willing to start building a version that works with 3rd party Tcl/Tk.

Re: [Matplotlib-users] number rendering in GTKCairo
Hello, On the Mac I use TkAgg and can output PDF files no problem. The only reason I was using GTKCairo was to get the PDF output which was not working with GTKAgg. I just updated to the most recent SVN from the one I was using from earlier today and now I can save to PDF in GTKAgg without troubles. Basically I just wanted something that was interactive till I made the plot to my liking then I could save the figure to a PDF. On the mac this worked with TkAgg without any troubles and now on Linux it works iwth GTKAgg without any troubles. Not sure what changed but thanks for the help.

[Matplotlib-users] possible to expand the current Colorcycle?
Hi, Is it possible to expand the colorcycle that matplotlib uses by default? in axes.py, class _process_plot_var_args, def _clear_color_cycle(self) It seems that self.colors are hardcoded to be self.colors = ['b','g','r','c','m','y','k'] ... is there a way to extend this? (Without changing the matplotlib code directly) I want to be able to extend it by ex. dashed lines or others.. i sometimes have a large number of plots to do, and the 7 default plot colors are not enough... I know I could manually make a handler in my program to handle the colors when I plot... but it would seem nicer if I could just pass a list of plot colors to matplotlib.

Re: [Matplotlib-users] power law fitting of data
Hi, You could use another package, like openopt and the generic optimizers that give you what you want provided that you create at least the gradient of the function (I didn't create a class that can numerically derive a fit function). For instance http://projects.scipy.org/scipy/scikits/wiki/Optimization/tutorial#FittingDatagives you an example. Matthieu 2007/12/6, Ping Yeh [EMAIL PROTECTED]: Hi, I have (x,y) data that I want to fit to the formula y = a * x^b to determine a and b. How can I do it? The current manual only lists linear fit and polynomial fit. Or, putting it in a more general setting, is there a module to do fitting to an arbitrary function? It would be something like pars = fit(x, y, func) where func is a function like y = func(x, pars) with pars a 1-D array.
