Re: [Matplotlib-users] error: Gtk* backend requires pygtk to be installed
Hi,
Went looking on examples page and found there was a file name demo_image.py
http://matplotlib.sourceforge.net/examples/axes_grid/demo_image.html
However for whatever reason the source code was not downloadable (404
error), so I copied it off the html page.
I'm not sure why the matplotlib examples page would contain weird
dependencies like that, rather than just having simpler examples.
As for 'pip', it is a replacement for 'easy_install', both of which
find and install python packages. pip is meant to improve on
easy_install, with new features and more stability.
And I think you figured out my exact problem:
I'd be questioning your configuration of matplotlib, there should be a rc
file somewhere, maybe you (or your distro) have set the backend to gtk by
default?
Yep, unfortunately in ~/.matplotlib/matplotlibrc
this line was set to
backend : GTKAgg
So I fixed that. The other solution I found is to have at the top of
the plotting script the matplotlib.use() statement so that it uses
something else for a backend:
import matplotlib # Do this before importing pylab or pyplot
#matplotlib.use('Agg') # Anti-Grain Geometry (raster images)
matplotlib.use('PDF')
import matplotlib.pyplot as plt
Thanks!
Mike

[Matplotlib-users] scatter plot with discrete colorbar
Hi I'm using the following code for insert a scatter plot in a figure in Qt. vmin=min(r_time[:]) vmax=max(r_time[:]) valores=np.arange(vmin,vmax+1) a1=self.ui.axes4.scatter(r_east,r_nort,vmin=vmin,vmax=vmax,c=r_time,edgecolors=none) b1=self.ui.fig2.colorbar(a1,values=valores,format=%.3f,spacing=uniform) The plot is ok and and the colors in the colorbar are ok, but for some reason the ticks are missing. I tried b1=self.ui.fig2.colorbar(a1,values=valores,ticks=valores,format=%.3f,spacing=uniform) but still the ticks doesn't appear. How can I get the ticks in the colorbar?

Re: [Matplotlib-users] Mac OS X 10.6 dmg install (Tim Gray)
I have followed these instructions to (almost ) the letter.
Only difference is that python was already installed at
/Library/Frameworks/Python.framework/Versions/2.6/bin/python
I also re-installed numpy.
Still no good with always the same problem - the absence of numpy.core.ma
Any suggestions?

Hi Tim,
From what I gather you are trying to install everything from source the
trying to install via the dmg. I did a fresh install of python,
matplotlib and a number of other packages today (on 10.6) and maybe it
would be helpful to see how to install from source. When installing
Python, be sure to use --enable-framework. I used a /usr/local prefix
though this may be somewhere else for you.
$ wget http://www.python.org/ftp/python/2.6.5/Python-2.6.5.tar.bz2
$ tar -jxvf Python-2.6.5.tar.bz2
$ cd Python-2.6.5
$ ./configure --prefix=/usr/local --enable-framework
$ make
$ make install
It appears that you have already installed numpy and so you would also
need the following:
dateutils
$ sudo wget
http://labix.org/download/python-dateutil/python-dateutil-1.5.tar.gz
$ sudo tar xzf python-dateutil-1.5.tar.gz
$ cd python-dateutil-1.5
$ sudo /usr/local/bin/python setup.py install
freetype
$
http://download.savannah.gnu.org/releases-noredirect/freetype/freetype-2.3.12.tar.gz
$ sudo tar xzf freetype-2.3.12.tar.gz

$ sudo ./configure --prefix=/usr/local
$ sudo make
$ sudo make install
libpng
$ sudo wget

$ sudo tar xzf pkg-config-0.22.tar.gz
$ cd pkg-config-0.22
$ sudo ./configure --prefix=/usr/local
$ sudo make
$ sudo make install
Finally, you should be able to install matplotlib from source using,
$ sudo wget
http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-0.99.3/matplotlib-0.99.3.tar.gz/download
$ sudo tar xzf matplotlib-0.99.3.tar.gz
$ cd matplotlib-0.99.3
$ sudo /usr/local/bin/python setup.py build
$ sudo /usr/local/bin/python setup.py install_*
*_
Hopefully this helps.

Every time I go to upgrade, the recommended procedure changes. The previous version still runs however, so I'll survive. It would be useful though to make a note for whoever packages official releases of matplotlib for OS X to make sure they are targeting the python.org install of python. numpy and scipy also do this. It makes it a lot easier to push python as a Matlab/IDL replacement if potential users can just download four dmgs (python, numpy, scipy, and matplotlib) and it all just works out of the box.

Re: [Matplotlib-users] basemap broken with matplotlib 0.99.3?
IIRC basemap contains Cython code, which would need to be recythonized with the latest Cython version in order to work with numpy 1.4.1. If you don't mind trying developer releases, use basemap 0.99.5 from http://www.lfd.uci.edu/~gohlke/pythonlibs/#basemap, which should work with numpy 1.4.1.

Re: [Matplotlib-users] Symbol not found
Ranjit, There are a couple of possibilities. The first is that the TrueType fonts packages weren't detected during the build, so matplotlib compiled without it, leading to your issue. I have also seen an issue where your ~/.matplotlib/ needs to be cleaned out of font-related files. Another possibility has to do with building both numpy and matplotlib. I have found that if I update the numpy source code and rebuild it, then I have to rebuild matplotlib. Now that you managed to get a complete build. I would go back and completely eliminate the build directories of matplotlib (and numpy, if you have it), and rebuild. Build numpy first if you have that from source, and then build matplotlib. So, first double-check your TrueType Font packages and see if you comply with the dependencies listed on the developer wiki. If so, then check your .matplotlib directory for any fontCache files and remove it. Lastly, do a complete clean and rebuild of matplotlib (the cleaning part is very important).
