Openchart2 Version 1.4 is now available for download from Approximatrix, LLC, after a quiet release candidate period.  The newest version of Openchart2 introduces refactored coordinate system code to improve extendability and functionality.  Version 1.4 also contains a new dot plot chart and associated optimized models for fast visualization of large quantities of data.

Version 1.4 brings incremental improvements to other parts of the code as well.  Radar plots have been improved significantly, plotting grids on the radar plot itself rather than relying on confusing coordinate system.  A box coordinate system, which frames the chart in a box with more traditional centered axes labels, has been added to the library.
