Refactoring PyChart

Summary

[EuroPython 2011] Jacob Hallen - 23 June 2011 in "Track Tagliatelle"

Description

PyChart is a very nice program for producing print quality graphs. However, it came equipped with a rather strange API, where every class was called T. It was also using the global namespace in strange and disturbing ways. Furthermore, it mixed multiple distinct tasks in some classes.

I will show how I went about refactoring the package in order to make a nice and clean API. This talk is focused on teaching refactoring methodology to beginner and intermediate level programmers. It will also give a brief introduction to how to make beautiful graphs with PyChart.
