Python SVG Charting Library

Project description

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.

You can install it with easy_install svg.charts, or from the subversion repository 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).

Changes

2.0.2

  • Updated cssutils dependency to 0.9.6 (currently in beta) to require the CSS profiles support.

  • Completed an SVG CSS profile according to the SVG 1.1 spec.

2.0.1

  • Added preliminary SVG CSS profile, suitable for stock CSS properties.

2.0

  • First major divergence from the Ruby reference implementation

  • Now implemented as a namespace package (svg.charts instead of svg_charts)

  • Changed XML processor to lxml

  • Enabled extensible css support using cssutils, greatly reducing static CSS

  • Renamed modules and methods to be more consistent with PEP-8 naming convention

1.2

  • Bug fixes

1.1

  • First public release
