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).
