Hi All,

I have released what will be the last JSci update for this year. The
main changes are to the graph classes. The internals of the graph
components have been re-organised, so there maybe knock-on effects to
any derived classes you have written. You now need to write much less to
extend the graph components.

There is now a StackedBarGraph class (thanks goes to Lindsay Laird) and
a GraphLayout class. GraphLayout is a layout manager for adding axis
labels and titles, I recommend looking at the GraphDemo example to see
how to use it (it is fairly straightforward). I have also added extra
functionality to DefaultGraph2DModel. It now supports series with
different x-values. Use setXAxis(float defX[]) to set a common/default
set of x-values to use for all series (just as before), and
addSeries(float newX[], float newY[]) to add a series which will use the
newX values instead of the defX values. The series are not required to
be all the same length.

The MathML Parser API has been modified and now includes the ability to
convert MathML to JSci source code (currently only works for simple
expressions).


Merry Christmas,

Mark
