+2011-01-15 Release 5.3.1
+
+Overview:
+
+This is the current stable release of PHPlot. This release focuses on
+providing better support and documentation for creating multiple plots on a
+single image.
+
+The PHPlot reference manual has been updated to match this release. Some
+new material has been added, including a new section on multiple plots per
+image, and a new example of overlay plots.
+
+
+Bugs Fixed in 5.3.1:
+
+#3143586 "Multiple plots per image - fixes & docs":
+ The reference manual now contains a section on multiple plots, and a
+ new example. A bug was fixed with SetLegendWorld and multiple plots.
+ Image border will now be drawn at most once. It is now possible to
+ restore the default 'automatic' behavior for axis positioning. Other
+ functions were changed to make arguments optional, so when called with
+ no arguments they reset to the default. The reference manual has been
+ updated with these changes too.
+
+#3147397 "Data colors missing with multiple plots":
+ The fix for bug #3049726 "Optimize color allocation" caused a problem
+ with multiple plots. This has been fixed. PHPlot will no longer truncate
+ the data color table at each plot. It will still only allocate data colors
+ as needed, but all of the pre-set or configured data colors will be
+ available for each plot.

+2010-12-04 Release 5.3.0
+
+Overview:
+
+This is the current stable release of PHPlot. This release includes new
+plot types and some new features.
+
+The PHPlot reference manual has been updated to match this release. Some of
+the sections have been moved, there are new examples for the new plot types,
+and a new section on tunable parameters has been added.
+
+
+New features in 5.3.0:
+
+#3093483 "Investing support chart types":
+ Added 3 new plot types: Basic OHLC (Open/High/Low/Close), Candlesticks,
+ and Filled Candlesticks. These are variations of plots that show the
+ performance of a stock or other financial security.
+
+#3111166 "Control legend colorbox width":
+ It is now possible to control the width of the color boxes in the
+ legend, using a class variable which is documented in the manual.
+
+#3117873 "Data value labels in more plot types":
+ Data value labels, which show the dependent variable values near the
+ data points, are now available for more plot types: lines, linepoints,
+ points, and squared. (These were previously available only for bars and
+ stackedbars plots.)
+
+#3127005 "Ability to suppress X/Y axis lines":
+ New functions SetDrawXAxis() and SetDrawYAxis() were added to control
+ display of the X and Y axis lines. (These lines were probably the only
+ PHPlot elements that could not be turned off.) In special cases, these
+ can be used to produce a "bare" plot image.
