matplotlib-users Mailing List for matplotlib

Hi Nicolas

I do not have any slides of this material yet. I will try at some point to
upload them on github, although I'm already working on tutorial part two,
so it may take a while.

In the meantime, I have a set of slides from 2012 when I presented this talk:
http://www.cspg.org/cspg/documents/Conventions/Archives/Annual/2012/155_GC2012_A_More_Perceptual_Color_Palette_for_Structure_Maps.pdf

Let me know if you're interested and I will upload them on github.


Hi Damon, yes, I did see your talk and Kristen's and I am really excited
there's good momentum on this topic. I will write you later today about
the matplotlib webpage, great idea.

Thanks to both for your feedback.
Matteo

Really great material (ipython notebook and videos), thanks a lot to you all.

Are the slides available somewhere by any chance ?

Hi Matteo,

Thanks for sharing this resource.

Also, I wanted to personally thank you for MyCarta.  It's a great
resource and Kristen Thyng and I have learned a lot from it.  Kristen
cited you in a talk she gave at SciPy 2014 last month.  We both gave
talks at SciPy 2014 about colour maps I think you might find
interesting.  They were recorded and put on YouTube by Enthought and
you can check them out
here<https://www.youtube.com/watch?v=Alnc9E1RnD8> and
here<https://www.youtube.com/watch?v=rkDgBvT-giw>.

I think it would be a good idea to link to your IPython (read Jupyter)
notebook, along with some of the work Kristen as done with matplotlib
colour maps, from the matplotlib web page.  Would you be amenable to
this?

All the best,
Damon

As a rule of thumb, modules that start with an underscore come
from a compiled C or C++ extension. In this case, the source
file in question lives in src/_backend_gdk.c of the matplotlib
directory.

Yes, you'll need GTK and its headers installed, something like 

  sudo apt-get install libgtk2.0-dev python-gtk2-dev 

should work on a Debian system, though you should probably just 

  sudo apt-get build-dep python-matplotlib

Hi,

I'm using the GTKAgg backend and when I run "import matplotlib.pyplot as
plt" in the Python shell, I get the   _backend_gdk error. I checked all the
files in my backend and there is no _backend_gdk.py. In fact, there are no
python modules that start with an underscore. It seems that some files were
not installed. Is there some kind of a gtk dependancy I need to install
before installing matplotlib? If so, where can I get it? My matplot version
is 1.3.1. 

thanks
