Approximatrix has released Openchart2 Version 1.2 to the general public.  The latest version introduces a BufferedChart type which performs all layout and drawing on a separate thread, improving Openchart2 performance when bundled with Swing and AWT applications.  In support of this new chart type, a rendering request system has been added to all renderable chart components to ensure Openchart2's ability to perform rapid and dynamic updates.

Version 1.2 is the first to require Java 1.5 (5.0) for operation.  The library can be downloaded from the Openchart2 download page.
