using Jython 'quick graphs' with non-VisAD data

[Tom Whittaker <tomw@xxxxxxxxxxxxx>]

I have added a little code to each of the 'quick graphs' in the Python 
graph.py module that will support the direct use of non-VisAD data 
objects.  For example, you can now do:

graph.lineplot((1,2,3,4,3,2,1), color='green')

or

graph.image( ((1,2,3),(3,4,2),(4,3,2)))

These changes were also added to the scatter() and histogram() methods, 
and were accomplished by seeing if the input 'data' is a PyList or 
PyTuple -- if it is, then the 'field()' method is called to create a 
VisAD Data object suitable for rendering.

This should be in the next VisAD release, although you can pick up an 
early copy at:

If you're using Python, I might also mention that I'm just about 
finished with a refactoring of the subs.py to correct a problem for 
people with multiple displays who wanted to use shapes, and to create a 
more extensible environment.  The refactoring will be mostly backward 
compatible with the current 'static' methods approach, but will also 
allow OO-oriented programmers the ability to use most of the 'display' 
methods as instance methods. For example:

disp = makeDisplay(maps)
....
disp.drawString("This is my string",(100,100))
....
