2008-11-29   Version 1.4.2 Jeff Armstrong <jeff.armstrong@approximatrix.com>

    - Fixed coordinate determination in dot charts that could lead to
      odd scaling behavior when manual scaling is enabled.
    - Removed unnecessary image scaling from the ImageRenderer
    - Modified chart renderers to return success boolean on completion
    - Fixed BufferedChart to reset rendering stop flags before 
      proceeding with chart drawing.
    - Slight refactoring of rendering stop flags in chart renderers to
      use synchronized methods to access the flag variable
    - Fixed calculation of bottom margin in classic coordinate systems

2008-5-22   Version 1.4.1 Jeff Armstrong <jeff.armstrong@approximatrix.com>

    - Official release of version 1.4.1

2008-5-14   Version 1.4.1_RC1 Jeff Armstrong <jeff.armstrong@approximatrix.com>
    
    - Introduction of an interactive extension to the ExtendedChartPanel
      that displays a tooltip with data next to the mouse pointer.
    - Fixed bug in BoxCoordSystem that caused incorrect fonts to be used
      for calculating and drawing unit labels
    - Fixes to BoxcoordSystem border calculations
    - Fixed bug where two sets of tic labels can appear on the x axis
    - Verified that axis directions may be reversed via manual scaling
      parameters
    - Unit tests introduced for select components and integrated into
      build system
    - Fix to AbstractChartDataModel to only use the autoscale flag and
      ignore the previously deprecated manual scaling flag
    - Fixes to AbstractDotPlotDataModel to properly compute scaled instances
      and handle axis flipping correctly

2008-4-7    Version 1.4 Jeff Armstrong <jeff.armstrong@approximatrix.com>

    - Fixed small bug in dot plots that used the internal image buffer width
      to scale transformations along the y axis mistakenly (should have used
      internal image buffer height).
    - Final release of Version 1.4

2008-3-22	Version 1.4_RC1 Jeff Armstrong <jeff.armstrong@approximatrix.com>

	- Added a Radar Plot example.

	  around entire plot)
	- Introduced a dot plot data model with efficient storage of data via an
	  embedded Image.  Support classes also introduced.
	- Added a new ImageRenderer class.
	- Improved handling of RowColorModels

	  axis labels.
	- Final release of Version 1.3.
	
2007-12-18	Version 1.3_RC2 Jeff Armstrong <jeff.armstrong@approximatrix.com>

	- Fixed possible negative Legend widths
	- Implemented generics for methods returning renderers from Swing components
	- Code improvements to BarChartRenderer

2007-12-4	Version 1.3_RC1 Jeff Armstrong <jeff.armstrong@approximatrix.com>

	- *MaximumValue(), *MiniumumValue(), *MaximumColumnValue(),
	  *MinimumColumnValue() methods now deprecated.
	- New API calls for dataset max/min setting/getting.
	- Bug fix to CoordSystem objects to force recomputation of the 
	  transforms whenever model data changes.
	- Cleanup of MultiScatter* classes.

2007-6-18	Version 1.2.1	Jeff Armstrong <jeff.armstrong@approximatrix.com>

	- Incremental bug fix / minor feature release.
	- Fixed problem in AbstractChartRenderer which caused issues when
	  with BufferedChart.
	- Introduction of AbstractChartPanel class to simplify switching out
	  Swing chart panels.
	- Minor code upgrades allowed due to Java 1.5 requirement.

2007-6-9	Version 1.2 	Jeff Armstrong <jeff.armstrong@approximatrix.com>

	- Final release of Version 1.2.  No code changes from RC1.
	- README updated to reflect new Java 1.5 (5.0) requirement.

2007-5-26	Version 1.2_RC1	Jeff Armstrong <jeff.armstrong@approximatrix.com>

	- Version 1.2 Release Candidate 1 released for public testing
	- Bug fix to the axis tick mark placement routines to correct problems
	  when graph scaling magnitude is less than one.
	- Added BufferedChart and BufferedChartPanel which performs all
	  rendering outside the main thread, improving GUI performance.
	- Introduction of a render update request system for all rendered
	  components to support the BufferedChart capabilities.  Should
	  lead to significant performance boosts in all chart renderings.
