The latest version of Openchart2 represents an incremental improvement to the charting library.  The latest version of Openchart2 incorporates improved APIs for setting and getting maximum/minimum data values.  Furthermore, CoordSystem objects now register as ChartDataModelListeners, eliminating problems with dynamic charts where data changes caused incorrect rendering of charts. 

The newest release has been tested with Sun Java 5.0 and 6.0 and Apache Harmony (Milestone 2 and higher).  Proceed to the Download page now to get the latest release.
