e.g. 50 bins in [0, 10] axis range.
Histogram2D overlay plotting in box or ellipse format was incorrect.
HistogramFactory.projectionY() did not work correctly.
Auto plotting range adjustment did not work correctly.
Auto tick label calculation did not work correctly.

Bug fixes
ITupleFactory:
createFiltered() did not work correctly.

Reading/Writing XML data file which includes complex ITuples works correctly now.
Characters '&', '<', '>', '"' were not escaped correctly in XML data file.
Memory:
Closed tree did not free the memory space.
Closed plotter did not free the memory space.
Grid lines did not be plotted correctly.
paida-3.2.1_2.6.1 was released on 2004/12/18.
This is a bug fix release.
I strongly recommend you to update!
Bug fixes
Weighted filling caused incorrect statistics.
Multiplication/Division of histograms caused incorrect statistics.
Log scale plotting sometimes raised an exception.
Now will give up reading broken XML data file.

New features
When overlay plotting, if the plotterStyle is not customized:
auto re-scaling
auto line coloring
auto marker shaping

You can select this engine by starting Python with '-guibatch' argument
>> python sample.py -guibatch
The zlib module is no longer required.
If you don't have zlib module, PAIDA always treat XML store files as unzipped automatically.
