Java API documentation
JChart2D's API is documented quite well. It provides
helpful information for java developers. Look especially at
the documentation for class info.monitorenter.gui.chart.Chart2D and the interfaces.
It is available for online-browsing and in form of a zip file (hosted at the sourceforge project page).
