Nathan Dunfield's personal Python-based plotting suite.

Uses: Matplotlib and Pandas

Installation

In the directory containing the file "setup.py" do:

python setup.py install

Replace "python" by "sage -python" if you're going to be using this inside Sage.

Advanced Installation: Using Tk backend within Sage

Matplotlib does all the 2D graphics for Sage, but unfortunately none of its GUI backends are compiled by default. (You can still use Matplotlib inside an IPython notebook or by saving things directly to graphics files.) The following suffices to compile the Tk backend on Linux, provided you have the tk-dev(el) package installed:

export SAGE_MATPLOTLIB_GUI=yes; sage -f matplotlib

This doesn't work on OS X because in addition to TkAgg, Sage will try to compile the native Mac backend, which fails since Sage doesn't include an Objective-C compiler. For OS X, download the source tarball for matplotlib, and then do:

cd matplotlib-*
sage -sh
echo '[gui_support]' >> setup.cfg
echo 'macosx=false' >> setup.cfg
python setup.py install

Also, if one has freetype or libpng installed via brew, one should temporarily unlink them to avoid conflicting with Sage's internal version.

Note that the TkAgg backend will be compiled against one's current version of Tk, which might not be the one that Sage is linked against. So inaddition one may need to recompile the Tkinter module via:

sage -f python
