``svg.charts`` - Package for generating SVG Charts in Python

============================================================



.. contents::



Status and License

------------------



``svg.charts`` is a port of the SVG::Graph Ruby package by Sean E. Russel.



``svg.charts`` supercedes ``svg_charts`` 1.1 and 1.2.



``svg.charts`` is written by Jason R. Coombs.  It is licensed under an

`MIT-style permissive license

<https://py-svg.svn.sourceforge.net/svnroot/py-svg/trunk/docs/license.txt>`_.



You can install it with ``easy_install svg.charts``, or from the

`subversion repository

<https://py-svg.svn.sourceforge.net/svnroot/py-svg/trunk#egg=svg.charts-dev>`_ with

``easy_install svg.charts==dev``.



Getting Started

---------------



``svg.charts`` has some examples (taken directly from the reference implementation)

in `tests/testing.py <https://py-svg.svn.sourceforge.net/svnroot/py-svg/trunk/tests/testing.py`.

These examples show sample usage of the various chart types. They should provide a

good starting point for learning the usage of the library.



Upgrade Notes

-------------



Upgrading from 1.x to 2.0



I suggest removing SVG 1.0 from the python installation.  This involves removing the SVG directory (or svg_chart*) from site-packages.



Change import statements to import from the new namespace.



from SVG import Bar

Bar.VerticalBar(...)

becomes

from svg.charts.bar import VerticalBar

VerticalBar(...)



More To-Dos

-----------



-  Implement javascript-based animation (See JellyGraph for a Silverlight example of what simple animation can do for a charting library).
