Is it possible to get the source code of pchart.sourceforge.net website for the history?

All the files are still on the sourceforge website.

http://pchart.sourceforge.net/

And what about scripts?

Old website is like a old release. You wont use old versions, but they are still interesting. It is the history of creation process of library, which we're using now..
