freetype. To get the most out of matplotlib, you will want to build
some of the optional GUI and image extensions, discussed below.
Matplotlib is known to work on linux, unix, win32 and OS X
platforms.
There are two kinds of matplotlib backends: vector based and raster
based. The vector based backends, SVG, PDF and PS, produce ASCII
text output files *.svg, *.pdf and *.ps. The core raster based
renderer is the http://antigrain.com (agg) backend. This is a high
quality 2D library that supports fast antialiasing, alpha blending
and much more. If you want to produce PNGs or GUI images that
support all of matplotlib's features, you should compile matplotlib
with agg support and use one of the GUI agg backends: GTKAgg, WXAgg,
TkAgg or FLTKAgg.
COMPILING
You will need to have recent versions of freetype, libpng and zlib
installed on your system. If you are using a package manager, also
make sure the devel versions of these packages are also installed
(eg freetype-devel).
matplotlib ships with a setup.cfg.template which you can use to
customize the build process. Copy it to setup.cfg if you need to
customize something. See that files for details of the parameters
you can set.
If you want to use a GUI backend, you will need either Tkinter,
pygtk , wxPython or Qt installed on your system, from src or from a
package manager including the devel packages. You can choose which
backends to enable by setting the flags in setup.cfg, but the default
is to automatically detect your installed GUIs and build support for
them. If you later find that you did not have a GUI toolkit like
pygtk installed when you built matplotlib, but now want it, you will
need to install the toolkit and rebuild matplotlib.
If you have installed prerequisites to nonstandard places and need
to inform matplotlib where they are, edit setupext.py an add the
base dirs to the 'basedir' dictionary entry for your sys.platform.
Eg, if the header to some required library is in
/some/path/include/somheader.h, put /some/path in the basedir list
for your platform.
Once you have everything above set to your liking, just do the usual
thing
python setup.py build
python setup.py install
WINDOWS
If you don't already have python installed, you may want to consider
using the enthought edition of python, which has scipy, numpy, and
wxpython, plus a lot of other goodies, preinstalled -
http://www.enthought.com/python . With the enthought edition of
python + matplotlib installer, the following backends should work
out of the box: agg, wx, wxagg, tkagg, ps, pdf and svg.
For standard python installations, you will also need to install
either numpy, in addition to the matplotlib installer. On some
systems you will also need to download msvcp71.dll library, which
you can download from
http://www.dll-files.com/dllindex/dll-files.shtml?msvcp71 or other
sites. You will need to unzip the archive and drag the dll into
c:\windows\system32
All of the GUI backends run on windows, but TkAgg is probably the
best for interactive use from the standard python shell or ipython.
The windows installer (*.exe) on the download page contains all the
code you need to get up and running. However, there are many
examples that are not included in the windows installer. If you
want to try the many demos that come in the matplotlib src
distribution, download the zip file and look in the examples subdir.
Important: There are known conflicts with some of the backends with
some python IDEs such as pycrust, idle. If you want to
use matplotlib from an IDE, please consult
http://matplotlib.sf.net/backends.html for compatibility
information. You will have the greatest likelihood of
success if you run the examples from the command shell or
by double clicking on them, rather than from an IDE. If
you are interactively generating plots, your best bet is
TkAgg from the standard python shell or ipython.
DISTROS: (rpms, apt, fink, osx, freebsd, gentoo, etc)
RPMS
To build all the backends on a binary linux distro such as redhat,
you need to install a number of the devel libs (and whatever
dependencies they require), I suggest
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
DEBIAN
matplotlib is part of debian (and ubuntu) so you shoule be able to
apt-get install it.
FREEBSD
http://www.freshports.org/math/py-matplotlib/
Gentoo
http://www.gentoo-portage.com/dev-python/matplotlib
OS X
All of the backends run on OS X. You will need to install
freetype2, libpng and zlib via fink or from src. You will also
need the base libraries for a given backend. Eg, if you want to
run TkAgg, you will need a python with Tkinter; if you want to use
WxAgg, install wxpython. See
http://matplotlib.sf.net/backends.html for a more comprehensive
discussion of the various backend requirements. Edit setup.py to
configure the backends you want to build as described above.
Note when running a GUI backend in OSX, you should launch your
programs with pythonw rather than python, or you may get
nonresponsive GUIs.
FINK
fink users should use Jeffrey Whitaker's fink distribution, which
supports the GTK, TkAgg, GTKAgg, PS, WX, WXAgg and Agg backends.

To use matplotlib interactively from the prompt, you need a special
interpreter that doesn't enter the gtk mainloop. One is provided in
examples/interactive.py. The coew functionality of this interpreter
was provided by Brian McErlean and John Finlay. See the header for
more info.
This will only work if you have pygtk compiled with threading. See
instrubtions below.
WIN32 Users
I haven't tested the interactive shell on win32. It is apparently
possible, but not easy, to get threading to work on win32. See
http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq21.003.htp
LINUX/UNIX Users:
To compile pygtk with threading, I recommend you make a backup of your
existing pygtk install tree and completely remove it
eg
> cd /your/path/to/python/site-packages
> cp -a gtk-2.0 /some/backup/dir
> rm -rf gtk-2.0
This is because I have found that recompiling pygtk with threads on top
of an existing installation w/o threads does not enable threads. Your
milage may vary.
Then from a clean pygtk src tree
> ./configure --enable-thread # and any other flags
> make install
TESTING threading
To test whether this install worked, try running this script
import pygtk
pygtk.require('2.0')
import gtk
import threading, time
def func():
n = 0
while 1:
print n
n += 1
time.sleep(0.1)
gtk.threads_init()
threading.Thread(target=func).start()
gtk.mainloop()
If it spits numbers back at you, you're golden.
TESTING with matplotlib
You should be able to make a simple plot with
> cd examples
> ./interactive.py
Welcome to matplotlib.
help(matlab) -- shows a list of all matlab compatible commands provided
help(plotting) -- shows a list of plot specific commands

matplotlib for MacOS X 10.3.9 or later and Python 2.5 and Python 2.6
matplotlib is a python 2D plotting library which produces publication
quality figures in a variety of hardcopy formats and interactive
environments across platforms. matplotlib can be used in python
scripts, the python and ipython shell (ala matlab or mathematica), web
application servers, and various graphical user interface toolkits.
Home page: <http://matplotlib.sourceforge.net/>
Before running matplotlib, you must install numpy. Binary installers
for all these packages are available here:
<http://pythonmac.org/packages/py25-fat/index.html>.
*** Back Ends ***
You may use TkAgg or WXAgg back ends; Qt and GTK support is not
provided in this package. By default this matplotlib uses TkAgg
because Tcl/Tk is included with MacOS X.
If you wish to use WXAgg then:
* Install wxPython from:
<http://pythonmac.org/packages/py25-fat/index.html>.
* Configure a matplotlibrc file, as described below.
For TkAgg you may use Apple's built-in Tcl/Tk or install your own 8.4.x
*** Configuring a matplotlibrc file ***
If you wish to change any matplotlib settings, create a file:
~/.matplotlib/matplotlibrc
that contains at least the following information. The values shown are
the defaults in the internal matplotlibrc file; change them as you see
fit:
# the default backend; one of GTK GTKAgg GTKCairo FltkAgg QtAgg TkAgg WXAgg
# Agg Cairo GD GDK Paint PS PDF SVG Template
backend : TkAgg
interactive : False # see http://matplotlib.sourceforge.net/interactive.html

-- Test merging from multiple branches.
-- ALMOST DONE : add print/save functionality. Currently you can save by right
clicking on the fig window, but you must have nothing in front of
the window. I suppose I need to first draw to a pixbuf. I would
also like to control the resolution.
UPDATE: high resolution printing. Resolution can be set from the
command line, but the GUI needs to be updated to allow resolution
to be set along with filename
-- DONE : fix text size calculations using pango layouts:
-- DROPPED : add a font selection dialog for the axis text
-- DONE enable vertical rendering for ylabels:
-- DONE with pango : enable anti aliasing for fonts
-- DONE enable fancy text labels (eg, greek letters, math symbols,
superscripts) ala TeX or unicode
-- DROPPED add a color selection dialog for the background, lines, and text
-- DONE allow interactive control of the plot from the python shell after
it has been launched using the cookbook thread recipe.
-- write a user guide
-- DONE allow more intelligent choice of tick labels and locs when panning and
zooming.
-- figure out why the positioning of dialog boxes based on position
and size of main window and dialog window doesn't work exactly as
expected. For example, the width of the dialog box is being
reported as being much smaller than it is. Is window pixels the
unit being returned by for gtk.Dialogs.get_size? Also, this isn't
working cross platform. According to the docs this is better
handled using size hints -- but I don't know how to use them, yet.
-- vlines and hlines disappear in some instance due to improper
clipping
-- One the errorbar demo the hlines do not always appear symmetric
about the x values. Is there an tranformation or rounding problem
occurring somewhere?
-- DONE Clip patches outside view port
-- DONE: subplot now takes a kwarg axisbg with color format string
just as axes does : Allow background color to be set for subplots
-- DONE Expose bug on win32 for axis text
-- Fix floating point bug on panx/pany where 0 is computed as 5e-17
UPDATE: hack workaround. If the distance of the tickloc from the
nearest integer is a small fraction of the view lim, just use the
integer
-- DONE: 2003-05-12 fixed _grab_next_args in figure.py : fmt process
bug on this kind of plot command (2nd of 3 has no format string)

-- DONE 2003-05-12 Removed some of the state handling of text labels
so they always redraw: interactive setting of x/ylabels doesn't
redraw all labels unless you click a forced redraw
-- CLOSED When you change a property using the OO interface in interactive,
the figure doesn't know to redraw.
Some possibilities:
1) redraw on all interactive commands. kind of heavy handled
2) override setattr on artist to signal a redraw event. kind of
heavy handled
3) allow derived classes to signal redraw events when nexessary.

available, middle click annotates, p, n, h for view stack,
-- relative distance mode
-- backend dependent cursoring
-- relative distance measures
-- on/off for button in status bar
-- interactive drawing and palletes
-- bk://sidl.bkbits.net/BuildSystem for py configure
-- post hacking points memo on site, ann and send copy to Fernando
-- loadrc() function, possibly replacing per-directory .matplotlibrc
files.
-- file save dialog for Tk? See Mayavi for the right call to make.
-- colorbar for dynamic images.
-- DONE Finish the coords notification for all backends - allow custom
formatters for toolbar
-- DONE an rrulewrapper demo
-- implement a new data clipping method with more exensive cache
interval
-- Humufr errobar
-- DONE why is tkagg loading init 2x
-- DONE add ishold and spy
-- Humufr's shared ticker bug
-- DONE figure should increment the figure if one already exists
-- CLOSED oplot
-- CLOSED override setattr in matlab interface for artists.
-- DONE cmap observer bug - see
~/python/matplotlib_support/test/cmap_observer_bug.py
-- DONE add connect function.
-- DONE add silent list
-- xmajor and xminor kwargs
-- DONE add hold option to plot
-- fix linestyle for collections
-- update ticklabels and range for colorbar when clim changes
-- DONE agg rotation bug for angles > 180
-- DONE mathtext color is wrong in PS
-- CLOSED reverse pie rotation
-- check keypress event handling on tooggle_images.

from pylab import *
plot(range(10))
title(r'$This\ is\ a\ test$')
show()
-- DONE fix contour mappable to work under changes in clim, cmap
-- DONE make subplot delaxes on other subplots under it.
-- DONE fix transoffset->operator calls in _backend_agg.cpp to handle
exceptions
-- keypress mods on pan/zoom broken in QT in linux
-- DONE linestyles in contour
-- check stabar in wx with toolbar = None or classic
-- nan handling?
-- kwarg processing - eg raise on unrecognized kwargs
-- provide a literal kwarg for text strings to pass thru directly to
the backend, eg ps symbol formatting
-- add gc warning to oo agg and FAQ
-- DONE check why lowest contour is not labeled in contour_demo2 and why
the colormap is still not applying to the contour.
-- the problem with attaching a mappable to the silent_list for
contours is that it doesn't carry over when the list is sliced, eg
when passing every 2nd contour and level to the labeler.
-- colorbar image origin with contour is broken in SVG; test PS
-- Bryan Cole's CXX type segfault
-- DONE japanese ft2font bug
-- Add backend draw cursor method
-- coords kwargs, 'axes', 'figure'
-- axes packing sizes
-- DONE direction fields
-- DONE add a force option to the add_axes code.
-- DONE move object inspector into Artist method
-- make toolbar visible or not
-- DONE hide lazy values make dpi and friends setters

construct it
-- restore __all__ to pylab and add ArtistInspector
-- create set_window_title in the figure manager interface expose this
in the figure command
-- multiple tick marks
-- DONE colorbar not updating in CVS
-- DONE tkagg figure not launching new figure until plot is called?
-- clipping off in date_demo_rrule (agg 0.5 offset bug?)
-- DONE merge qt patch.
-- properly handle sys.arv, so that it does not conflict with library
usage of mpl. mpl processes -Dagg, --verbose-helpful, etc, itself,
which can conflict with code that uses mpl as a library and process
options itself.
-- DONE Darren's black band ps image problem.
-- Martin's zoomhist bug
-- Add shading for patches and patch collections.
-- tex system call problem
-- tex rendering looks fuzzy (dvipng version or flag problem)

-- JPL and NIST screenshots...
-- John Gill's patch!
-- Fix latex texmanager caching bug that is preventing the cache from
recognizing a font change

#ifndef AGG_CONFIG_INCLUDED
#define AGG_CONFIG_INCLUDED
// This file can be used to redefine certain data types.
//---------------------------------------
// 1. Default basic types such as:
//
// AGG_INT8
// AGG_INT8U
// AGG_INT16
// AGG_INT16U
// AGG_INT32
// AGG_INT32U
// AGG_INT64
// AGG_INT64U
//
// Just replace this file with new defines if necessary.
// For example, if your compiler doesn't have a 64 bit integer type
// you can still use AGG if you define the follows:
//
// #define AGG_INT64 int
// #define AGG_INT64U unsigned
//
// It will result in overflow in 16 bit-per-component image/pattern resampling
// but it won't result any crash and the rest of the library will remain
// fully functional.
//---------------------------------------
// 2. Default rendering_buffer type. Can be:
//
// Provides faster access for massive pixel operations,
// such as blur, image filtering:
// #define AGG_RENDERING_BUFFER row_ptr_cache<int8u>
//
// Provides cheaper creation and destruction (no mem allocs):
// #define AGG_RENDERING_BUFFER row_accessor<int8u>
//
// You can still use both of them simultaneouslyin your applications
// This #define is used only for default rendering_buffer type,
// in short hand typedefs like pixfmt_rgba32.

// Curve converter class. Any path storage can have Bezier curves defined
// by their control points. There're two types of curves supported: curve3
// and curve4. Curve3 is a conic Bezier curve with 2 endpoints and 1 control
// point. Curve4 has 2 control points (4 points in total) and can be used
// to interpolate more complicated curves. Curve4, unlike curve3 can be used
// to approximate arcs, both circular and elliptical. Curves are approximated
// with straight lines and one of the approaches is just to store the whole
// sequence of vertices that approximate our curve. It takes additional
// memory, and at the same time the consecutive vertices can be calculated
// on demand.
//
// Initially, path storages are not suppose to keep all the vertices of the
// curves (although, nothing prevents us from doing so). Instead, path_storage
// keeps only vertices, needed to calculate a curve on demand. Those vertices
// are marked with special commands. So, if the path_storage contains curves
// (which are not real curves yet), and we render this storage directly,
// all we will see is only 2 or 3 straight line segments (for curve3 and
// curve4 respectively). If we need to see real curves drawn we need to
// include this class into the conversion pipeline.
//
// Class conv_curve recognizes commands path_cmd_curve3 and path_cmd_curve4
// and converts these vertices into a move_to/line_to sequence.

//==================================================rasterizer_scanline_aa
// Polygon rasterizer that is used to render filled polygons with
// high-quality Anti-Aliasing. Internally, by default, the class uses
// integer coordinates in format 24.8, i.e. 24 bits for integer part
// and 8 bits for fractional - see poly_subpixel_shift. This class can be
// used in the following way:
//
// 1. filling_rule(filling_rule_e ft) - optional.
//
// 2. gamma() - optional.
//
// 3. reset()
//
// 4. move_to(x, y) / line_to(x, y) - make the polygon. One can create
// more than one contour, but each contour must consist of at least 3
// vertices, i.e. move_to(x1, y1); line_to(x2, y2); line_to(x3, y3);
// is the absolute minimum of vertices that define a triangle.
// The algorithm does not check either the number of vertices nor
// coincidence of their coordinates, but in the worst case it just
// won't draw anything.
// The orger of the vertices (clockwise or counterclockwise)
// is important when using the non-zero filling rule (fill_non_zero).
// In this case the vertex order of all the contours must be the same
// if you want your intersecting polygons to be without "holes".
// You actually can use different vertices order. If the contours do not
// intersect each other the order is not important anyway. If they do,
// contours with the same vertex order will be rendered without "holes"
// while the intersecting contours with different orders will have "holes".
//
// filling_rule() and gamma() can be called anytime before "sweeping".
