matplotlib is a 2D graphics package that produces plots from python
scripts, the python shell, or embeds them in your favorite python GUI
-- wx, gtk, tk, fltk currently supported with qt in the works. Unlike


application servers, and many scientific and enginneering disciplines.
With a large community of users and developers, matplotlib is
approaching the goal of having a full featured, high quality, 2D
plotting library for python.

A lot of development has gone into matplotlib since the last major
release, which I'll summarize here. For details, see the notes for
the incremental releases at http://matplotlib.sf.net/whats_new.html.

Major changes since matplotlib-0.60

- The alpha version of the users guide -
http://matplotlib.sf.net/users_guide.pdf. There are still a number
of sections to be completed, but it's a start!

- The matlab namespace renamed pylab - if you are upgrading from a
version older than 0.64, please remove site-packages/matplotlib
before upgrading. See
http://matplotlib.sourceforge.net/matlab_to_pylab.py

- New plot types: contour plots (contour), polar charts (polar),
horizontal bar charts (barh), pie charts (pie), sparse matrix
visualization (spy and spy2). Eg,
http://matplotlib.sf.net/screenshots.html#polar_demo

- Full ipython http://ipython.scipy.org integration in the "pylab"
mode for interactive control of matplotlib plots from the python
shell.

- A significantly improved interactive toolbar for panning, zooming,
zoom to rect - see
http://matplotlib.sf.net/tutorial.html#toolbar2.

- New backends: FLTK, Cairo, GTKCairo

- Text - rotated mathtext, mathtext for postscript, text bounding
boxes

- Colormaps - 14 colormaps built-in
http://matplotlib.sf.net/screenshots.html#pcolor_demo

- Images - performance optimizations for 4x faster large image
handling, PIL support, interpolation and colorbar improvements,
imread

- Event handling for capturing mouse clicks, movements, keypresses,
etc. - same pylab interface works across GUIs. See
examples/keypress_demo.py, examples/picker_demo.py,
examples/coords_demo.py

- set and get matlab style property introspection -
http://matplotlib.sf.net/examples/set_and_get.py

- improved dates handling for dates and date string formatting from
0000-9999, eg
http://matplotlib.sf.net/screenshots.html#finance_work
