NetCdf: how to obtain min and max for variable

Question

NetCdf: For a grid you can obtain the minimum and maximum value for data in the following way:

MAMath.MinMax dataMinMax = grid.getMinMaxSkipMissingData( data); float min = (float) (dataMinMax.min); float max = (float) (dataMinMax.max);

but what if you just have a ucar.nc2.Variable. Can you also obtain this kind of information? Kind regards Onno van Logchem
