Please note that the information in the PDF documentation on pages 4 and 5 is slightly out of date. The instructions for running the demo application are no longer correct, because the classes in demo.jar have been moved into jfreechart.jar.
I've posted an interim document install.pdf with corrected instructions. When version 0.6.0 is released (I've decided to put this back till December), it will have a completely rewritten PDF documentation file. The rewrite is due to a switch from Microsoft Word/Adobe Distiller to Latex/PDFLatex.
In the meantime, sorry for any inconvenience...full refunds are available
