It was the time of the month again. I need to scrape some data off a webpage for my pet project.

With almost 1 year worth of data, it’s time to do some work on it and perhaps give some useful results for people and of course for myself.

I started to search for a library to perform graphing, I initially thought it would be easy to find a decent open source library. To my dismay not much. Maybe i’m using a wrong query. A few queries later, here are some of the better libraries that I manged to find

1. PChart         http://pchart.sourceforge.net/
2. GraPHPite  http://graphpite.sourceforge.net/
3. JPGraph     http://www.aditus.nu/jpgraph/   [Pro Version available] Meaning not fully open source
4. Libchart     http://naku.dohcrew.com/libchart/pages/introduction/
5. Sparklines  http://www.sparkline.org
