I've downloaded the example application and looked over the documentation. This appears to be a very nice product.
I'd like to start learning how to use this tool, particularly with charts similar to the 'Time Series' examples given. Where do I start? Which classes are used to create this type of chart?
Any ideas or samples of code will be greatly appreciated.
Thanks,
Jason

Hi Jason,
You should start by looking through the JFreeChartDemo.java source file, and also the ChartFactory.java source file. One thing to keep in mind with the demo application - the data is hard-coded, which is not recommended (it just makes it easier to have a self-contained demo).
The PDF documentation is, unfortunately, a little out of date, but you might want to have a quick read through it as it does describe a few of the concepts. Unfortunately I've changed a few class names, so it might just be confusing...
The Javadoc HTML is fairly up-to-date.
Regards,
DG.

It is not just that the PDF file is out dated, but the javadoc available is also incomplete.
The JFreeChartDemo uses many classes of which the no javadocs are avalable and no source code are provided.
Please provided these materials. We would wasting our time with trial and error trying to figure out what classes or functions does what.
