The return value from the sample call is a visad object.
If you are using a point probe and are sampling at the animation time
(and if there are actually times in the display) then you will get a VisAD
Real object. If there are no times then the sampleAtTime just samples spatially
and will return a VisAD FieldImpl object.  Likewise, the other probe types
will give some structure (e.g., a FlatField).

To access the value of a Real you can do: 
sample.getValue();
which will return the (double) value of the Real in its native units.

The menu call back routine specified in the menu items is a jython routine.
So you could do the above which will result in a call to the jython routine
addNewData. addNewData can then call back to the displayControl. e.g.:

def addNewData (displayControl):
       displayControl.selectData('Add new parameter');

Note: I changed the methods on the Jython control for selecting data.
They are:
public void addData(String message);
public void addData(String message, String callback);
public void replaceData(String message);
public void replaceData(String message, String callback);

If no call back is specified then it defaults to 'handleData'

If the user does choose something new then the call back routine
is called.
