This has been bothering me for a while, too. So I added
a new method signature to visad.DataImpl:
public double[][] computeRanges(RealType[] reals)
throws VisADException, RemoteException;
where the returned array is double[reals.length][2],
giving the min and max value for each RealType in the
reals array. Note min and max may be Double.NaN. The
DataImpl.main() method shows how to use this.
Cheers,
Bill
