If you want to visualise your ODB data you can either use the Magics plotting package or the Metview workstation/batch system (which itself uses Magics). Both packages allow the processing and filtering through ODB SQL statements.
Metview has an extensive support for plotting and examining ODB data, see their Tutorials for more information and examples. See ODB in Magics to learn how to use Magics Python interface for plotting ODB data.
